Hypno-potamus is my favorite side-villian in this series, so I'm going to make something special about it. ;)

3rd pov

On the screen, it shows the Turtles fighting a robot. "Let me start at the beginning. I first met the Turtles in a battle that raged on for hours. Since that first battle, I knew-- That's not me, I'm over there." The voice said. The camera turns away from the fight to show an Earthworm with a blue coat and has blonde hair with a big hair poof in the front. "Prepare to taste the awesome wrath of my incredible--" Warren said, but was squished by Donnie landing on him. "I knew after this first fantastical battle, we would meet again. And again." Warren said as it showed flashbacks of bowling pin mutants in a bowling alley, and him on the roof, but got knocked off by a soccer ball as they passed by jumping from roof-to-roof.

"I am Warren Stone, former number one news anchor, and the greatest foe of  the Teenage Mutant Loser Turtles." Warren intro ducked to no one, except for a trophy of him when he was human, and an Oozequito.

"Ha-ha! Uh...mm?" Warren laughed, then check his watch. "Ooh, I'm late." Warren said. He jumped down to his desk and landed face first, but recovered, and turned on the TV, making it go to the News Channel. "I am Carly Balmaceda filling in for the completely forgotten Warren Stone." Carly said, which made Warren growl in irritation. "The search for the missing hypnotist, Mezmer-Ron,and his Hippopotamus, Doug, and the missing child, Y/n Dragoey, continues. In unrelated news, a monster, hippo in a magicians tuxedo is terrorizing local magicians, and stealing their trick animals. And with no animals, there's no magic." Carly said.

"News flash, those wannabe hero Turtles will be hot on that mutant hippo's trail, which will make setting a trap for them so easy. Either that or search for the kid... Ehh, I think they'll go for the mutant hippo. With their destruction coming at my hands, I won't be reporting the news, I'll be the news." Warren narrated.

Y/n's pov

Me and my brothers were hopping roof-to-roof, and Raph was in a hippo costume. "You sure that evil mutant hippo is around here?" Raph asks as he too off the costumes head off. "It's a million degrees in this thing." Raph added as he tugged the collar of the suit.

"I'd be happy to wear it, if you need a break." Mikey said as he put the head on. "No, no. No, no, no, no. I'm the leader. The leader wears the suit." Raph said as he took the head from Michaelangelo. "Well, I mean, he's got a point. Raph is the most hippo like." Leo said. Me, Mikey, and Donnie chuckled.

"I'm gonna attract him, I need a little more of the female hippo scent." Raph requested. Donnie pulled out a perfume bottle, that's the shape of a female hippo, and sprayed it on Raph. "Jazzy fresh." Raph said.

"Help!" A voice said. "Guys, that must be him." Raph said. "A hippo magician is trying to saw my magic worm in half." The voice continued as we went over to the source.

We were now at the playground, and we were on top of the roof of the jungle-gym. We looked down to see that the worm was in a box, with its head sticking out, and two arrow signs are pointing to it.

"Is anyone find this whole thing a little-" "Odd? Just-" "Magic worm?" "Totally legit." Leo said, then Donnie, then Mikey, and then Raph said. Raph put on the hippo head and jumped off of the jungle-gym. "Don't worry, raph will save you." Raph said, and landed on his feet.

"Uh... 'ey, 'ey. Raph stuck." Raph said as he tried to get his feet free from a sticky mat. "Not again." Me and Leo said at the same time, groaning in annoyance.

As Leo and Donnie tried to get Raph unstuck, I slid down the slide. "Wee!" I said, and reached the bottom.

The worm started laughing maniacally. "Stepped right into my goop trap." The worm said. Raph pulled the head off. "Your what now?" Raph said in confusion (Favorite scene in the episode). "Goop trap." The worm said. "Talking magic worm?" Mikey questioned in amazement as he slid down the slide head first, in his stomach., and I moved out of the way before he could run into me.

"That was all a ruse. For I am Warren Stone, your greatest foe, and-" Warren said as pulled pulled away the disguise, and posed, but his villain introduction was interrupted by Leo poking the hair poof. "I'm sorry, Warren who?" Leo questions. Warren waved Leo's finger away. "Stop it. Stone. I'm your greatest- I'm your greatest fo-" "Ah, don't tell me. What are you? Um, Worm Man?" Leo guessed, interrupting Warren. "No, no, no, I'm Wa-" "Can someone get me unstuck?" Raph requested as he took the hippo head off him and held it in his arm. "Fine." Leo groaned as he and Donnie went to go hero Raph, while me and Mikey were playing on the playground.

"Uh, greatest nemesis, here." Warren said gesturing to himself, but he was ignored. "Stop." Warren said, but nothing happened. Warren let out a battle cry and leaped onto Leo's head. "Ah, get it off of me. It's gross." Leo said as he tried to swat Warren off of him.

A second later, he smacked the worm mutant off of him, and sliced him in half. Everyone stopped what they were doing. "Oh, what did you do?!" Raph questioned/exclaimed. "He was on my head. I panicked." Leo said. "Is he gonna be okay?" Mikey asks as Leo was chewing on his nails in nervousness. "'Is he gonna be okay?'" I repeated his question. The other part of his body landed on the ground. "He's in two pieces!" I exclaimed as I pointed to the part that landed on the ground just now.

"You fools." Warren said. We all freaked out and hid behind Raph. "You've unleashed my ultimate power. Now I can-" Warren said, making it dramatic, but was interrupted once again, but by Mikey. "You can clone yourself?" Mikey questioned. "No, I regenerate. It's an amazing power, put it's incredibly painful." Warren corrected and explained. "Fascinating. How long does the regeneration process take?" Donnie asks. "Several... days." Warren answered. "And you grow back with double the strength." Mikey guessed. "No." Warren said. "But four times the size." Raph guessed. "If I don't grow back  twice as strong, why would I grow back four times as big?" Warren questioned in annoyance. "I don't understand you." Leo said.

We were now walking away from the park. "Can we get some pizza now I'm hungry." Raph asks as he put the hippo head back on. "Are you sure he's gonna be okay, guys?" Mikey questions. "I'm fine, you swamp-stinking, county-fair-prize losers!" We heard Warren shout out to us. "You heard him, he's fine." I said. "Ugh, I had my fists set on bustin' up a magic hippo. What a waste." Raph grumbled.

(Time-skip)

We just got a call about the hippo was at the Burgundy Center. We were on the glass roof. "Now, you sure the hippo is in there?" Leo questions, making sure this was the right place. "Uh, yes, I picked it up on my scanner. A current occupant called it in." Donnie confirmed as he cut out a big circle in the glass. "Now, explain it to me again, why can't I wear the suit?" Raph questions. "Oh, we've been over this." Leo said. "You ruined that woman's 95th birthday." Donnie stated. "She's fine." Raph said in annoyance. "I'll do you in the suit proud." Mikey said. Yeah, he's the one now wearing the hippo suit. "Treat her with respect. And be careful." Raph said.

Then Mikey got kicked and fell to the ground. The rest of us landed on the skylights, out of sight, and Leo pointed one of the lights at Mikey. Mikey then started to do a dance. "What is he doing?" I ask. "Someone's mating dance he saw on Nature Planet." Donnie explained. "Hippo, I'm right here." Mikey called out. "Hippo-Man. Your biggest fan is here. She loves magician's animals. Bunnies, doves, tigers and was hoping you brought some." Leo called out over the PA system. "I hope he likes me." Mikey said. "He will. Of course he's gonna like you. You're adorable." Leo said.

Mikey continued to dance but then stopped as a new voice came over the PA system, a familiar one, but I can't remember who. "Breaking news." Thw voice said. We pulled out our weapons, except Mikey. The lights pointed to a spinning chair as the news program music started playing. "You may have beaten me before, but I'm a little tougher this time." The voice said. "You see, I've enhanced myself. I've really grown into my role as your greatest nemesis. I'm really pumped for our little tête-à-tête." The voice said as he started slow clapping as the chair turned, to reveal a worm guy, but buff.

"Ah, my eyes!"

"Jumpin' Jack Flash!"

"Okay."

We said at the same time, seeing that this guy in front of us is unnatural. "I think I'm gonna have to bleach my eyes after this." I said as I covered my eyes and turned my back to the guy. "You're not a hippo, are you?" Raph said. "No, I'm not a hippo! Do I look like a hippo to you?" The worm questioned in annoyance. "Maybe a baby hippo?" Donnie suggested. "I am not a hippo, and stop interrupting me. I called the hippo sighting." The guy said.

"Guys! He's Current Occupant!" Mikey exclaimed in realization. "Yes, he gets it. I am Current Occupant." The guy said and confirmed. "And we're here to save you from the hippo magician." Mikey said. "Where is he?" Mikey asks.

"No, you green idiot. It was a ruse. There is no hippo. I'm Warren Stone, your greatest nemesis." Warren said in frustration and annoyance. "Prepare to meet y-" Warren was about to say a common villain line, but was interrupted by an explosion from behind him.

"Ta-da! Hypno-potamus has arrived." Hypno-potamus said, having a grat villain entrance. "Finally!  It's the thing we actually care about." Raph said as put pushed Warren to the side, and out of the way.

"You're up Mikey." Raph said, pushing Angelo forward. "Hello, future Mrs. Hypno-potamus." Hypno said. 'Gross' I said to myself. Me and Leo were grossed out, Raph was wiping tears away from his eye with a tissue, and Doonie just leaned against his staff.

"See? My hippo is more hippo-ey." Mikey said as he came over to us, but without the head. We then heard Hypno-potamus freak out by the fake head he was holding. He then saw us, and we nervously chuckled. "Pulled the ol' false-Jenny on me. Ugh. I gotta say, has been the worst mating season." Hypno said.

'Wait a minute, he sounds familar..familiar... No! It can't be!' I thought to myself in realization. "Wait, Meztli?" I questioned. (I just searched up a boy name that started with 'Mez') "Wait, you know him?" Raph asks. "Of course I do! He's my Unlce." I said. "UNCLE?! Wait, what's an Uncle?" Mikey asks. "Okay, say that Splinter has a brother. So that would mean that his brother would be your Uncle." I explained. "Y/n?! W-What are you doing here? And where have you been?" He questioned. "I'm here with my brothers to stop a magic hippo, which turns out to be you. And what do you mean 'Where have I been'?" I asked. "Haven't you seen the news? You've been reported missing a while ago." Meztli stated. "But I'm not missing, they took me in as their sister." I said, gesturing to the Turtles. "Okay, I guess?" He said in a unsure tone as he scratched the top of his head. "Well, I got some villainy to continue, but maybe when I'm not doing that, we can do some Unlce and Niece bonding time." Meztli suggested. "Sure! Now, let the battle begin!" I said and got into a fighting position.

"Ah, fell the power." Hypno-potamus said as he pulled out his metal rings from his suit and make them levitate. "That is one well-dressed evil mutant hippo." Leo said. The guys the got into fighting positions. "Fellas, let's smash this guy." Raph said. We all charged him. "Sleight of hand." Hypno said as he blocked Leo's attack with one of the metal rings. We continued fighting, and with each attack we made, it was blocked by a metal ring. Raph activated his, as he calls it, 'Power-Smash Jitsu', but Hypno-potamus dodged, and the floor now has several cracks. Meztli threw his rings at Raph, but he blocked and dodged them we all charged, again, and jumped, attackong from above.

3rd pov

As the gang of heroes were about to land an attack, "Mezmer-roo!" Hypno-potamus said in a hypnotic tone of voice, and they were all hypnotized and were all floating in mid-air. Hypno-potamus did a villainous laugh. "Now, which one should I take care of first, hmm?" He asked himself. "Big Red? Baby Blue? No. I think I'll start with you, you lovely trickster." Hypno-potamus said and went towards Mikey. Yeah he doesn't forgive Mikey for tricking him.

Meanwhile... Warren scoffs. "Some nemesis. He doesn't even know their rela names. Except for his niece, I guess." Warren said to himself. He spots his old trophy, and picks it up.

(Time-skip brought to you by Meztli and Y/n playing Dungens & Dragons in the past)

Long story short, Warren stopped Hypno-potamus. Then, Leo fell on him, and they were now un-hypnotized. "What just happened?" Leo asks as he rubbed his head. The gang walked up to Hypno-potamus and saw that he was in his own trance. "I think we won." Raph said with a grin. "My plan must've worked." Donnie said. "And it was my plan to use your plan." Raph said. "That doesn't make any sense." Y/n deadpanned. "Your welcome everybody." Raph said, ignoring Y/n's statement. "I think by rejecting him I broke his heart." Mikey said in a saddened tone. "Ooh, sheesh. This suit is too much power." Mikey said as he took the suit off and handed it to Donnie.

"No!"  A voice said. You were all confused of where it came from. Leo turned around to see that Warren was squished in Leo's shell. "I saved you loser Turtles and child by hypnotizing that beast and saving your lives!" Warren exclaimed. "What'd you just call my Uncle?" Y/n questioned. If looks can kill, he would've disintegrated. "I mean, uh... a wonderful person you call an Uncle." Warren said, with a nervous smile, correcting himself.

Leo pulled him off. "And you are?" Leo asks, with no expression on his face, like he was bored, and not rememberingthe worm-guy.
