Jack Andros is the wielder of the MonTrix, created by Azmuth, who made the original Omnitrix.

Together with Ben Tennyson, Gwen, Kevin and the Plumbers, he stopped wars, invasions and defeated powerful foes that would make his original universe look like ants to a lizard.

But..... what if he got transported into other universes?

What if he got sent into other worlds that need a hero to save them?

Hong Kong (Pacific Rim Universe)

Otachi and Leatherback launches an attack on Hong Kong, but the Jaegers Striker Eureka, Crimson Typhoon and Cherno Alpha stood in their way. Unfortunately, Crimson Typhoon and Cherno Alpha are destroyed with Leatherback launching a electromagnetic wave from its backthat shuts down the power within the city and Striker Eureka.

Leatherback circles the defenseless Jaeger while Otachi walks towards the city. Striker Eureka's pilots attempts to stop Leatherback with flare guns, but only manages to succeed in angering the Kaiju. However, a tyrannical roar forces him to stop as he turns at the source.

From a few miles away, in the waters Leatherback sees a huge cyan colored body T-Rex with a green underbelly that is the same size as him. It has fins on its arms. It also had a fin with dark blue spines from its head to it tail. Oddly, it had a light blue and black hourglass symbol on its chest.

"I'd suggest you back off from my friends. Unless you wanna face the full might of Poseidon Rex, the Tyrant King of the Seas!" The sea monster roared, prompting Leatherback to roar as well.

Leatherback charges on fall fours and throws a punch, but Poseidon Rex sidesteps the attack before biting down unto Leatherback's electromagnetic organ on its back.

"Yeah!" Herc Hansen said.

"Come on, Andros! Kick his ass!" Chuck Hansen yelled.

Poseidon Rex succeeds in tearing off the organ and throws it away. However, Leatherback whirls around with such speed and grabs him by the head before he spins once..... twice..... and throws him away.

Poseidon Rex roars as he flew all the way to the harbor and crashes into multiple containers, vehicles and even a bridge. But manages to claw his feet on the ground and stops, just as Leatherback emerges from the end of the harbor.

Leatherback roars into the air as he charges like a gorilla towards Poseidon Rex, who runs full speed. Poseidon Rex then spin and smashes his tail into Leatherback's face, knocking him backwards.

Poseidon Rex then bites his face before lifting him up and throwing him down into another area.

Leatherback recovers and sees a cran nearby. Grabbing it, he swings full force against Poseidon Rex's face, knocking the sea creature bacl before swinging at him again, forcing to on the ground.

However, Poseidon Rex gets up and spins and smashes his tail against Leatherback's face again. He is temporarily stunned before a second before lunging for another attack, only to be hit by the tail again, stunning him as he falls.

Leatherback slams his gorilla fist on the ground as he bites a container in his mouth n half. But Poseidon Rex bits on in his back again and tries to lift him up. Unfortunately, Leatherback is just too heavy and he throws him away. Leatherback safely lands on his feet as he roars in fury.

Poseidon Rex  knew he is a serious disadvantage against Leatherback's bigger arms. "Time to go Ultimate!" He slaps the MonTrix symbol, which causes four diagonal spikes to appear as he evolves.

Poseidon Rex begins getting bigger till he towers over Leatherback in 100 meters tall and 120 meters long. His body gains a Spinosaurus like body with a huge sail being 50 meters overall. His face became similar to a crocodile with orange reptilian eyes.

"ULTIMATE POSEIDON REX!" He roared as he and Leatherback charged and locked fists and claws with one another.

Ice Island (Pokemon Universe)

Lugia, who had Ash and Pikachu, is slowly being overpowered by the Legendary Bird Trio; Articuno, Zapdos and Moltres.

However, an intense black and red energy beam tore through the skies and forces the three Pokemon to dodge.

Everyone looked u to see a black dragon with blue veins coming from the dark skies with thunder cackling above him.

"You're not the only ones who can cause destruction!" Alatreon declared. "Let's see you handle a living natural disaster!" He looks at Lugia. "Get Ash and Pikachu out of here! I'll handle these three!" The Diving Pokemon nodded.

"Be careful Jack!" Ash called out as he Pikachu and Lugia flew away, leaving Alatreon to the Bird Trio.

"Alright birdbrains! Come get some!" Alatreon roared with Articuno, Zapdos and Moltres screeching.

Articuno fired an Ice Beam, Moltres launches a Flamethrower, and Zapdos unleashed a Thunderbolt. All headed towards Alatreon, but he fires powerful ice crystals that hit Zapdos and lighting bolts that struck Moltres and Articuno. The three Bird Trio fell down as Alatreon got hit by their own attacks.

"Urgh!" He grunts in pain as Moltres' Flamethrower manages to hurt him, but remains unaffected by Ice Beam and Thunderbolt. He had no weaknesses against the Thunder Element and the Ice Element is only effective if he's on the ground.

The Bird Trio recovers and are angrier then ever. They let out powerful screeches as they flew towards Alatreon. The Blazing Black Elder Dragon roars as his "crown" glows white and he descends down to resume his battle against Artiicuno, Moltres and Zapdos.

Elsa's Castle (Frozen Universe)

"Is it not nice to throw at people!" Anna snapped at Marshmallow, who threw them out and throws Olaf's body near her head. She grabs a snowball to throw it at him.

"Whoa, fiesty pants!" Kristoff said as he and Jack held her back. "Relax, just clam down."

"Yeah just let the snowman be." Jack said.

"I'm calm." Anna said plainly as she, Jack and Kristoff turn and return Olaf as one. However, she turns and yells as she throws the snowball at Marshmallow.

"Oh come on!" Kristoff and Jack exclaimed.

Marshmallow turns and sees the snowball hit him in the shoulder, before roaring in anger with spikes coming from his hands and feet.

"See, now you've made him mad!" Kristoff said as the three backed away from the angry snowman.

"Run! Run! Run!" Jack shouted as he, Kristoff and Anna began running from the now chasing Marshmallow. The three jump off a cliff and slides down to safety with Anna sliding under Kristoff. However, Marshmallow jumps from a large distance and lands behind them as he growls menacingly.

Jack, Anna and Kristoff all head towards the tress as Marshmallows resumes his chase. As they duck under many trees, Anna suddenly had an idea.

She ducks under a tree and whacks it against Marhsmallow's face, causing him to fall on is back.

"Haha!" Anna laughed as she catches up with the two boys. However, they came to a dead end as a cliff too high for them to jump up stood in their way. Just then, Marshmallow emerges from the tress as he glares down at Anna, Jack and Kristoff

"Got any form to handle him?" Kristoff said to Jack in panic, who is furiously on his MonTrix selecting the form they need. help from

"Already on it." Jack said as he selects the hologram of a mammoth-like creature. He slams down on the symbol, causing him to be consumed by a light blue flash. The others covered their eyes. When the light died, they are in awe at Jack's newest form.

It is a Woolly Mammoth on steroids that is bigger than Marshmallow. His brown body had mixed with red, blue and white colors. It had a brown plating on its head, most likely acting as a battering ram and a shield. Its tusks, and legs are also covered by the same plating. And lastly, it had the MonTrix symbol placed on its right shoulder.

"GAMMOTH!" The Giant Beats let out a trumpeting roar. After roaring, he smirks at the now smaller Marshmallow.

"Alright Marshy, get ready to face the Gammoth by the trunks!" Gammoth said as he stomps towards the now frightened Marshmallow.

Tenroujima Island (Fairy Tail Universe)

Acnologia shot his mouth open as he roars, his round head plunging into Master's abdomen and making him gag blood. Acnologia began to drive Makarov back as he screamed. The Dragon growled loudly as he used his legs and pushed, making Makarov screamed louder as he fell on his back. The Dragon drove his left claw onto Makarov's chest and squeezed, crushing it.

Makarov let loose even more agonizing screams as Acnologia was towering over him, his chest bleeding from being crushed. Acnologia's claws were embedded into his skin and not releasing as his mouth had all teeth bared.

Slowly, Master stopped screaming, which somewhat confused Acnologia. The Black Dragon reared away, still left claws on chest, but what surprised him was Makarov smiling. Pretty soon, his smile broke into a laughter, or a light chuckle.

'This is what a father does for his children.' He thought as his gaze was hazy and Acnologia opened his mouth once more. 'I have nothing to forget. I can die as a happy man...'

Suddenly, a flash of blue light causes his eyes to widened in shock, which also caught caught Acnologia's attention.

"GET AWAY FROM HIM!" A powerful roar echoed as Ultimate Disufiroa came into view and body slams into Acnologia, causing him to let go of Makarov and tumbled alongside the Frozen Seraphim Elder Dragon.

"Jack!"

Acnologia and Ultimate Disufiroa manages to get back on their feet and growled menacingly. Ancologia roars angrily as trees and rocks are sent tumbling by his powerful roar. However, Ultimate Disufiroa is not intimidated and as he got in his back legs, the Frozen Seraphim Elder Dragon roars even an even more powerful roars as mists of ice encased his body with flames surrounding him like a tornado.

"Like hell you will take him from Fairy Tail!" Ultimare Disufiroa as he fired an intense fiery draconic beam at Acnologia, in which Acnologia responds with his own Dragon Roar.

Alfea (Winx Club Universe)

The remaining members of the Winx Club, Specialists, and the teacher and students of Alfea are slowly being overpowered by the Army of Darkness, which iare xcreated by Icy who had the Dragon Flame in their grasp.

All seemed lost, until a wall ifre fire blocked the Army of Darkness from entering Alfea as blue flames incinerated most of the soldiers.

Then, from above, a silhouette of a girl appears with a chinese orange dragon behind her roaring. Next two her is a creature with a snake for a rail, a pair of draconic wings and two heads, one is a lion while the other is a goat. And had the MonTrix symbol on its chest.

They are Bloom and Ultimate Teostra!

The Winx Club cheers for their leader's arrival while the guys and other fairies who didn't met Jack earlier are in awe of his powerful form.

"Mind if I join in?" Bloom asked as she incinerated another row of monsters. Whilst Ultimate Teostra spreads his ashes around and gnashed his teeth, sparking them ashes as they exploded.

"You!" Icy spat, enraged and dumbfounded. "It's not possible! You...and...and the wings! And the flying! How the hell did you get your powers back!?" She turns to Ultimate Teostra with equal fury. "She would've died if you hadn't stepped in, shapeshifter!"

"And I never let you do that!" Ultimate Teostra retorted. "Otherwise, I'd introduce to you one of my forms that will definitely wipe the floor with you!"

"I never lost them in the first place!" Bloom said. "You thought you were rid of me, Icy, well you thought wrong!"

Unfortunately, Icy and her sisters had taken flight. "You think you're so special, Bloom!" Icy spat. "But you seem to have forgotten that you're not the only one who possesses the power of The Dragon Flame!"

"I'm not even gonna argue with your delusions, Icy!" Bloom said defiantly. "So I'm just gonna kick your skanky ass!"

"And this time!" Flora said as she, Musa, Tecna and Stella joined her in the air. "Bloom's not alone!"

"I don't know how you do it, Bloom," Icy said. "But you and your friends always know how to push my buttons!" She shot a stream of frozen darts at the fairies and Elder Dragon, which Bloom countered with a flamethrower spell.

"I won't let you hurt my friends any more, Icy!" Bloom shouted as she threw another fireball, "I'm gonna finish you once and for all!"

"Catch me if you can!" Icy shouted as she dodged the fireball, then flew farther away, drawing Bloom after her. Ultimate Teostra decides to follow Bloom to make sure she doesn't get nearly killed again.

Dragon Nest(How To Train Your Dragon Universe)

Drago's Bewilderbeast had just killed Valka's Bewilderbeats and is now the Alpha Dragon. Hiccup and the other looked on in horror as the surrounding dragons gathered at Drago's Bewilderbeast and bowed. Drago Bludvist smirks.

However, a huge earthquake broke him out of his thoughts as every one, even his Bewilderbeast, nearly lost their footing, before the ground breaks near the dead Bewilderbeast.

When the mist cleared, it showed a yellow-eyed white, humongous creature that rival the Bewilderbeast in size, but much slimmer. Its body is covered in silver and white scales with jagged rows of spines on its back with a thick tail. Its most distinctive feature is the shovel-like shin on its face. Strangely, it had a black and light blue hourglass placed on its chest.

"UKANLOS!" The White God stands on his back legs and let out a deafening roar. After he stops roar, Ukanlos looks back at the Bewilderbeast he had met a while ago. Now he was dead. He turns to black Bewilderbeast with fury.

"You have killed my brethren," He snarled, surprising everyone except those from Berk that it spoke. "Now I will avenge him!" He roars again.

The black Bewilderbeast took that as a challenge and roars as well, ready to defend his newest title. He thrusts his tusks forward as  he did to kill the previous Alpha, but Ukanlos blocks with his shovel-like chin. He shoves (no pun intended) them away before raising his head high and slams his chin down unto the black Bewilderbeast's head.

It got mad and thrusts its tusks under him.

"JACK!" Hiccup yelled horrified, thinking his friend and ally might be killed the same way it killed the Alpha in the Dragon Sanctuary.

"Oh no you don't!" Ukanlos yelled as he grabs the tusks with his bare hands and held them at bay as he pushes the Bewilderbeast.

Drago's mouth dropped in shock as his Bewilderbeast gets overwhelmed before being shoved (again, no pun intended) to the ground. It got made and launched its icy mist breath towards Ukanlos.

However, for someone his size, Ukanlos leaps from the side and fired his own attack. His, though, its a concentrated ice beam that struck the Bewilderbeast head on, literally. It roars in pain as he fell down to the ground, writhing in pain.

"Never best with the best!" The White God said as he roars and charges.

Heatherfield (W.I.T.C.H Universe)

"Jack, now would be a good time to switch into that red spiked beats from, like NOW!" Irma said as she and the rest of her team backed away from the now giant Cedric.

"It's Akantor! And I'm trying in case you haven't noticed!" Jack yelled as he furiously hits the MonTrix button, which for some reason, hadn't been working after a few minutes.

"Preapre to meet your doom, Guardians and freak boy." Cedric

"Damn it MonTrix! Work!" Jack yelled as he slams the symbol. This time, the light blue is replaced by orange and scans Cedric. This surprised everyone. After a few seconds, it stops and the MonTrix's female voice spoke.

"Unknown DNA Sample Acquired. Scan Complete. Unlocked and available on Playlist 13." It siad in a feminine voice as the orange turn back in light blue and beeping, indicating it is ready to act once again.

"Do it!" Cornelia yelled.

Wasting no time, Jack slams the MonTrix symbol, causing him to be cinsumed by a light blue flash. One thing the Guardians noticed is that it was much brighter compared to his other forms. When the light subsides, they, including Cedric, looked in awe, if not, fear.

Jack is now a bipedal monster that towers even Cedric as he is at a whopping 150 meters (492 feet) tall and 165 meters (541 feet) long. It had yellow eyes with orange pupils with ears. It had charcoal skin with its chest and the bottom of its tail being gray. It had two muscular legs with four toes with the tip gray colored. Its arms are long and has four claws with tips along being gray. It had three rows of maple-leafed spikes on its head to its tail with the top being gray and the bottom charcoal. Finally, it had the MonTrix symbol on the left chest.

Jack looked at his hands, or rather, claws in amazement and shock. "I'm.......... Godzilla?" He said. After a few moments, he let out a toothy grinned and raised his arms in a power up fashion. "I'M FREAKING GODZILLA!" He let out a roar identical to the 2004 one and looks down at the now puny Cedric.

"I've always wanted to try this." He grinned as he his mouth and dorsal spines glowed neon blue. "Atomic Breath!" He fired his signature beam at the green snake, causing him to cry out in pain as the radiation beam burned his skin.

"Come on tough guy! Let's get ready to rumble! Cause the King of the Monsters is here!" He raised his head and let out his signature roar once again.

SSSSSHHHHHHHRRRRRRRREEEEEEEEEEEEEEOOOOOOOOOONNNNNNNNGGGGGGGGGGGKKKKKKKK!!!!!!
