The yellow fog filled the bubble formed by Susan Storm the Invisible Woman, causing the monsters to choke on the fumes as they fought the X-Men and remaining Avengers, the billowing cloud was so thick it kept the horde outside from seeing the battle within.
Believing their masters defeated they retreated back to the nest in the city.
By the time the smoke cleared and the bubble was dropped, the situation inside had changed drastically.
Warbeast was on her knees crying her eyes out while her two daughters held on to her for dear life, lost and confused as their worse impulses were gone. Tigra had curled into a ball rocking herself as Black Cat and Mary Jane looked down with caution at the
prone feline, the rest of her 'pack' looked around dazed and confused. The other abominations were all in a state of confusion as the serum dissapated.
She Hulk looked around in confusion as she stared down at Iron Man, his armor battered from the blows she gave him. "Tony?" Stark opened one eye then the other, breathing a sigh of relief knowing she was back in control of herself.
"Looks like it worked Stretch..." Grumbled the Thing as he moved away from the abomination he fought earlier. "Er... too bad about the mansion... though."
The Thing stared wide eyed as he witnessed his friends and loved ones holding onto their sides as if in pain, the gas had reclaimed the abominations minds once again but it also began spreading the infection like an air born disease. Susan Storm lurched
as she began to bulk up, growing several feet taller as she turned.
Rogue burst out of her uniform as she swelled and bulked with power, holding onto Storm who was growing along with her, Cyclops grunted as he out grew his clothing, his visor snapping in two as it fell off his face.
Over the last few minutes the X-Men and Fantastic Four had all turned into abominations, each exhausted as they now stood several feet taller.
"Ah... NUTS!" Frowned Ben Grimm as he looked down at the group of heroes, now hulking monsters. "Now whata we gonna do?"
