The group soon returned to Avalon with Garokk as their prisoner as they saw a man with large white angelic wings in an X-Men suit waiting for them.

"We've got trouble, and it looks like you're gonna have to handle it pretty quick." Angel said. "As soon as we landed, I've spotted a small army preparing to attack the Atmospheric Generators near Avalon while I was scouting."

"Then if those generators are destroyed, the Savage Lands will be plunged into an ice age." Tear said. "We can't let that happen."

"Definitely not. We have to stop them, now." Cheetah said.

The group soon headed into the Jungle Ruins as they fended off the soldiers and monsters that were attacking the Atmospheric Generators as one of the leaders was the last one standing.

"This is impossible! Mikhail assured me you would never get this far!" The soldier said.

"Mikhail...Mikhail Rasputin my older brother?!" Colossus said in shock.

"Yes, he is our leader and you would do well to fear him for he is a Horseman of Apocalypse." The soldier said.

"Do you think we're scared of you? We've fought enemies way worse than you." Belladonna asked.

"And if you don't want to meet the same fate as your soldiers, I suggest you scram." Lei said. "But first, tell us where Beast is."

"He is being held prisoner in an ancient underground Nuwali temple. But it cannot be reached on foot and you cannot use your ships. We have hidden surface to air rocket launchers everywhere." The soldier said.

"Thanks for your help." Lei said as the soldier ran off.

"So if we want to get to the underground temple, we'll have to find a way through the shrine Shanna mentioned in order to gain entry." Lana said.

"The Nuwali Temple, correct?" Cheetah asked.

"The very same it would seem." Lana said.

"Very well. Let us go." Cheetah said.

The group made their way through the caves and path of the Jungle Pass as they soon reached the Nuwali Temple, only to find a humanoid green Pterodactyl at the entrance.

"What the hell is that?" Simon asked.

"This is Karl Lykos. Although now he addresses to Sauron." Cheetah said. "He's kind of in the same boat as I am. He has been cursed to become a humanoid pteranodon and has to feed off of energy to survive."

"So that makes him a vampire dinosaur in a way." Miriam said.

"In a sense, yes." Cheetah said.

"Wait, Sauron? As in the Lord of the Rings Sauron?" Agito asked.

"Not...exactly. But I wouldn't be surprised if that was the inspiration for the namesake." Cheetah said.

"Ah I have heard the X-Men and Brotherhood were in Avalon with a group of heroes. So we meet at last, Cheetah." Sauron said.

"Yes. It would seem we both have been cursed with these forms and penchant to hunt for survival." Cheetah said.

"Yes, while Karl Larkos needs human energy to survive, I need the energy of mutants in order to maintain my form as Sauron." Sauron said. "Besides, I owe Ka-Zar so much for the many, many times he's thwarted my plans. Killing you will be most pleasurable."

"It's a shame. I would've been glad to call you a kindred spirit." Cheetah said.

"Maybe with Karl Lykos, but I Sauron, shall destroy anyone who interferes with my plans!" Sauron said as he took flight.

"Time to clip this bird's wings." Baozhai said.

"Don't waste your breath with energy attacks. He'll just absorb them and grow stronger." Cheetah said.

"So physical attacks are the way to go then." Garr said, drawing an arrow.

"We can deal with that." Yangus said.

"Finally, a challenge." Ajna said, firing an arrow as it flew up to Sauron before warping to the arrow as she slammed Sauron to the ground with her axe.

"Coming through! Typheous' Maul!" Yangus said as he leapt up, his axe imbued with wind as he slams down.

"Got the upper hand!" Duran said, preparing to swing his sword as Sauron was pulled into a whirlwind before being slashed multiple times before finishing with a sword slam that dispersed the vortex. "Spin Slash!"

"I'm not finished with you just yet! Resshou Souhajin!" Garr said, slicing down then upward which launched Sauron into the air as Garr thrusted Igtenos upward, unleashing a beam of compressed wind as it slashed through Sauron continuously.

"Don't think this is the end of it!" Sauron said before he collapsed to the ground.

"Now that Sauron's out of the way, it's time to enter the temple." X said as they stood before two large temple doors. "Just hold on, Beast. We're on our way."
