After freeing the prisoners in both the south and north living quarters, the group finally reached the grand hall as cries of pain were then heard before they spotted a blonde-haired man in a red and orange suit with portable flamethrowers being continuously shocked inside a force field as he screamed in pain.
"Oh man, this guy looks like he's in a lot of pain. We have to get him out of there." Agito said.
"Right." Aya said.
The group quickly destroyed the device that was powering the forcefield as the man was soon freed.
"Are you alright, Pyro?" Scarlet Witch asked.
"Y-Yeah, thanks for freein' me, and if you're lookin' for Apocalypse, he's already long gone. He left Abyss in charge, and he's every bit as nasty." Pyro said.
"Abyss… One of the Four Horsemen. He's bad news." Cheetah said.
"Yeah, and if ya ever saw him, you'd give a wide berth." Pyro said.
"So if we want to free Genosha, then we'll have to defeat Abyss." Miriam said.
"It's your funeral, luv. Good luck, 'cause you're gonna need it." Pyro said before Blink warped him out as the group soon entered the Genoshan Council and in the center was a strange blue being with spring-like arms as he was seen pulling bombs to his stomach as they were being sucked in by a small vortex inside it.
"HAHAHAHAHA! And what do we have here, a bunch of rugrats teaming up with the X-Men and the Brotherhood?! And is that Cheetah I see? Oh this is too much, laughable to say the least, hahahaha!" The mysterious being said.
"Well, this guy's a barrel of laughs." Toya said.
"So you're Abyss, one of Apocalypse's Horsemen." Al said. "Speaking of which, where is he?"
"He found what he was looking for and left, harmonic DNA to be exact. And the funny thing was, of all the mutants in Genosha, only Quicksilver had it." Abyss said.
"My son?!" Magneto said.
"That's right. But right now you all have bigger problems, namely, me." Abyss said.
"Don't be surprised when you go down." Toya said.
"Hahaha! I welcome you to try!" Abyss said.
The battle soon started as everyone hit the Horseman with their strongest attacks before he soon ran off.
"After him." Jessica said as the group gave chase and followed him onto a Dirigible he boarded as they were flying through the sky.
"You fools certainly are determined to get yourselves killed. Well then, come along and I'll try to accommodate you." Abyss said.
"You shouldn't underestimate us." Luke said as the group continued the assault before Abyss sucked them into the dark dimension inside his stomach as he was on his last legs.
"End of the line." Belladonna said.
"Yes. We just need to blow up these bombs around us, and we're out of here." Zamazenta said.
"In that case… Let's light them up." Jessica said. "Sizzle!"
"Firestorm!" Vargas called.
"Grant mine enemies a final rest. Flame Burst!" Jade said as three fireballs descended from the sky and converged, creating a cloud of fire.
"Fire in the hole!" Ace said as the bombs went off, disabling the Dirigible as well as knocking out Abyss as they landed on a small piece of land near Genosha.
"You know, for a Horseman, he might be the weakest one." Simon said.
"And that's going to speak volumes of what the others are going to be like." Cheetah said.
"An exemplary job. With Abyss out of the way, the rest of Apocalypse's guards should be no trouble. Once you've finished, return to me at the Sanctuary. Then we can travel to the X-Mansion and begin our search for Polaris. We must discover where Apocalypse is holding her prisoner." Professor Xavier said as a portal was then formed as the group stepped through.
