"Am I in time for the party?" Scarlet Witch smirked as she floated down to land next to her sons with her red magic-like powers.

"You're in time to die!" Mark snarled as he lunged towards her, deflected by a shield she easily created around herself.

People noticed the fight and started panicking, screaming as they ran back indoors or found the nearest place to take shelter away from them.

"Is there any way we can get rid of the symbiote without hurting Mark?" Sean asked Peter as Natasha fired a bullet at him, the black substance absorbing the shot without getting damaged.

Peter opened his mouth to answer, but was interrupted when Mark turned his focus to him and used one of his tentacles to slap him aside.

"Dad!" Sean cried, tearing his gaze from his father's body flying through the air just in time to see Mark reach towards him with a clawed hand.

Sean ducked out of the way as Iron-Man blasted an ion beam at Mark, Mark roaring in response as the symbiote took the brunt of the attack.

"What sort of beast is he?" Thor wondered aloud as he smacked Mark with his hammer, electricity arching along his body as he screamed in pain.

"Don't hurt him, he's still Mark!" Sean shouted, stepping between the god and his former friend.

"I don't understand." Peter mumbled as he rejoined the fight.

"The only way Mark can get rid of the symbiote is by rejecting it, but he isn't." Peter frowned.

"He's trying to protect us from it, but can't control the symbiote." Sean realized.

"So how do we blow this bitch up?" Falcon interjected impatiently.

"We don't, I have the cure." Peter reminded him.

Sean opened his mouth to chime in, but froze when he saw Mark create a hammer in hand out of the symbiote, electricity cracklings on its surface.

"Great Odin's beard." Thor whispered in shock as the symbiote swung the hammer at Thor.

"This is your fault Sean, you should've used my powers when you had the chance." Mark taunted as he hit Thor hard enough to send him flying much to Sean's surprise.

"Leave my friends alone!" Sean pleaded desperately.

"I told you they would all die, and I never back out on my promises." Mark replied coldly.

"I was Anti when you were my host. Now I am Dark, for I will bring this world into the darkness it belongs in." Mark continued, striding towards Sean despite the shots Natasha fired at him repeatedly.

"Leave him alone!" Felix demanded as he ran in front of Sean with his super speed.

"How pathetic." Dark scoffed as he used his strength to slap him aside into a building before Felix could react.

"Hey!" Scarlet Witch yelled to get Dark's attention.

As Dark turned to face her, she used her powers to create wispy tendrils that floated towards Dark to stop his tentacles.

Instead, Dark evaded her attack and used one of his tentacles to stab her in the stomach.

Shocked, Scarlet Witch stumbled back as Dark retracted the tentacle before she collapsed to the ground.

"Mom!" Robin and Felix cried in unison, racing towards her.

"Guys wait!" Sean shouted, creating a web that held Dark still temporarily.

"Mom." Robin whispered in remorse as he knelt down by her with Felix at his side, silent tears trailing down the twins' faces as they closed her lifeless eyes.

Dark broke free of the webbing and knocked them both out, tossing their bodies into a wall for good measure.

"That's it! I don't care who the hell you are under that symbiote, you can't kill my friends without signing your own death will." Iron-Man growled in rage as he flew towards Dark.

"I can't let you kill him Tony!" Steve interjected as he grabbed his leg.

"Steve let go, he's a monster-"

"Mark is not a monster, the symbiote controlling him is!" Steve argued defensively.

"I'm sorry Steve." Iron-Man apologized before boosting up into the air.

Dark rose up to meet him, his gaze emotionless as he smashed Iron-Man down into the ground, creating a crater in the street.

"How do we get him to take the antidote?!" Sean yelled frantically at Peter as Dark and Tony engaged in hand to hand combat.

"Someone will have to hold him down while someone else makes him drink it!" Peter answered as he joined the fray, fighting Dark off long enough for Tony to get back up.

"Thor tackle him, I'll take the antidote!" Falcon barked, taking the antidote from Peter before taking off into the sky over Dark.

Thor swung his hammer at Dark, but was shocked when he moved faster than his eye could follow and tore Iron-Man's suit to shreds before knocking him out with a punch to the face.

"Hey emo man!" Falcon taunted before dive bombing toward Dark like a bullet out of the sky.

Dark retaliated by side stepping his attack and tearing his wings off as he flew by, making him collide into a building and drop the vial.

Felix quickly caught it and moved towards Dark until he was attacked by his tentacles that forced him to the ground.

The vial fell out of his hand and shattered on the street, decimating any chance they had at getting rid of the symbiote.

"I'll go get more from the lab." Peter offered.

"You really think I wouldn't get rid of them? I'm not as stupid as you." Dark sneered.

"You can't win. There's only five of you now." Dark smirked in triumph.

"Let's even out the numbers." Dark continued as he used his tentacles to grab Tyler, Natasha, Thor, Steve, and Peter, keeping them in the air despite their struggling.

"Now it's just you and me Sean." Dark grinned maliciously, stepping towards him.

"Mark-"

"I am not Mark!" Dark cut off Sean furiously.

"I know. Mark wouldn't do this, he would want to end this for good by rejecting the symbiote for good." Sean replied.

"Would he now? It seems more like he wants to keep me around to become more powerful." Dark mused, voice dripping with sarcasm.

"He wouldn't." Sean shook his head.

"Oh but he would. After all, he wants nothing more than to live up to his father's legacy and be just like him." Dark laughed as he squeezed Steve tighter.

"You don't have to have powers to be like him." Sean protested.

"What would Amy want?" Steve spoke up.

"She'd want me to be perfect, and that's what I am now." Dark declared proudly.

"I need you back Mark! I need my wingman, my reason for surviving high school, my gaming partner, and my best friend back." Sean pleaded tearfully, reaching out towards him.

Dark started to reach towards him as well until he abruptly began screaming in pain as fire enveloped his body.

"Burn bitch." Iron-Man huffed as he held his thruster against Mark's back until the symbiote retreated into a small ball that Peter picked up once he hit the ground.

"I-is he....." Sean trailed off, to afraid to finish his sentence.

His concerns were answered when Mark groaned softly, his body covered in bruises and cuts.

"What-oh my god-did I-is she-" Mark stammered, unable to complete a thought as he glanced around at the carnage around them.

"I'll explain once we get to Avengers Mansion." Steve promised as he helped him up.

"We'll talk when we get there too." Peter told Sean as they took to the air using their webs.
