The human world.
In London a mansion was seen before someone started running to it before using a staff to jump over it.
The person in question was none other than deathstroke who quickly rushed to the Window. (You'd almost think he was back to his old ways seeing this)
He takes out Explosive Gel and uses it to make himself a door before spraying the floor with something revealing the lasers.
Placing some equipment on his staff he shot two ropes at the wall making some noise.
In the house was also hawkman who's wings shot up for a second before going back down.
Deathstroke quickly used his staff to move quietly to one part of the room before making a hole with the explosive gel on the ground which seemed to have awaken Warren.
Jumping down Deathstroke found some old relic before picking it up.
Thats when the doors opened up showing hawkman.
"See something you like?" Hawkman asked.
Only for Deathstroke to throw explosives at him making them blow up before blowing up a wall and ran out.
Running to the street he rushed to some hooded person before hawkman flew at them but yelled holding his head.
The person in question was Mesmero who grins at this.
Only for metal poles to surround him making him gasp.
"So, your the one who took control of deathstroke. Magneto said appearing before Mesmero tried to take control of him. "Don't even bother. Your mind games don't work on me. Now release Deathstroke." Magneto said having the poles wrap around him tightly making him groan.
"All right." Mesmero said releasing his mind as he groaned.
"Where am I?" Deathstroke asked.
"And as for this Relic. Lets see if it was worth it." Magneto said as they flew off not knowing hawkman saw all this.
"Magneto." Hawkman said.
Meanwhile at x mansion.
The Logan and the realm defenders specifically Anne,gus,vee,Sasha,maria,Apollo,luz,frosta,marcy,eda,korra and hunter came to visit the x men.
Everyone was outside out back ready to play a game of baseball.
"Ok remember guys a fair game. No powers or magic." Beast said.
"Wheres the fun in that?" Gus asked.
"True enough. But let's keep things simple today since we could use some normality after so much crap." Beast said.
Maria levitated the ball as she adjusted her glove.
"Hold up! Thats not fair!" Gus yelled.
"She's doing so to adjust her glove. No cheating. Lets go!" Beast yelled as maria put it back on before throwing it at Bobby.
Only for him to ice his bat and hit it.
"Ok here we go again." Sean said.
"MUTANT BALL!" Gus yelled.
"Oh brother." Korra said as she was next to hit before Using Airbending sending it away.
"Damnit." Beast said.
And so the game went sideways letting students use their powers to play.
"This is way better." Vee said hitting the ball before turning into a wolf and ran off before going to second base.
Only for a Shadow to come over them before they saw hawkman.
"Hawkman? It's been a while. What are you doing here?" Logan asked.
"You said if I ever needed help I could come here. I need your help. Something involving Magneto and some other guy. With markings on his face." Hawkman said making eda narrow her eyes.
Meanwhile
Magneto arrived in a room seeing Mesmero being interrogated by Master Mind.
"What have you learned?" Magneto asked.
"Theres a second half to this spider Stone. It resides in London Museum. Together, they form a key." Mastermind said.
"To what?" Magneto asked.
"I don't know. His Mental powers are impressive. I need more time. MasterMind said.
"No." Magneto said spinning Mesmero around quickly making him groan as he became disoriented before Mastermind took a closer look before gasping. "What is it?" Magneto asked.
"The Relic will help open the second door to the most powerful Mutant that almost black adams own power. En Sabah Nur. You will know him as...Apocalypse." Mastermind said making him frown.
Meanwhile
"Are you sure this is the man you saw?" Charles asked hawkman showing his face.
"Thats not a face you forget." Hawkman said.
"Nope. You had the right idea coming here. We've dealt with him before but haven't heard anything about him till now. Last time we saw him he used adrien's dad to cause a distraction so he steal some rings." Korra said as they were shown.
Chris read his Gabriels mind to see he made a deal with Mesmero so he could steel the rings.
"Why? Why use others?" Hawkman asked.
"Cause thats what he does. He uses people to get what he wants. Whatever it is he's after can't be good. The rings are used as a key to something. But we have no idea as to what." Charles said.
"And you think this old Relic he stole is part of it?" Hawkman asked.
"Maybe. Theres still a lot we don't know. We do know however those he's just another puppet. Someone else is pulling the strings." Korra said.
"Who?" Hawkman asked.
"No idea. But we need to get moving. If Magneto knows this he'll want the second half to keep it out of Mesmero's hands." Charles said.
"So we better get moving." Korra said.
"Absolutely!" Frosta said walking in. "Lets gear up and take care of business." Frosta said.
"Yeah, thats not gonna happen for ya. This is for those who do follow the rules." Eda said.
Oh come on Frosta said.
Stay here eda.
Meanwhile
"How could this happen!" Magneto yelled as Mesmero was gone as was the Relic.
"I don't know. One Minute he was there and the next he was gone. Along with the Relic. If he joins the two relics together." Mastermind said.
"That is not going to happen! We're going to London." Magneto said.
Meanwhile
At the London Museum the doors were broken open by Magneto and he and his pawns walked in.
"Find him." Magneto said as they spread out.
While this was going on the X men and the realm defenders also arrived.
"London. Feels weird being here." Apollo said.
"Not a fan of the place?" Eda asked.
"Eh, Not really." Raynare said.
"Eda, Care to inform our stowaway we've arrived?" Charles asked.
"Eh?" Luz asked before opening a cabinet finding Frosta .
"Whoa! Hey!" Frosta said.
"Dude." Anne said shaking his head.
"What? You need all the help you can get. It's villan." Frosta said.
"Ok fair enough on that." Anne said pulling her out.
Rushing inside however though they found the place trashed.
"Oh man." Eda said.
"Looks like he's here." Korra said before seeing his pawns show up.
"Looks like we got X men." Pyro said laughing.
"And I bet they wanna play!" Deathstroke said throwing explosive cards at them before kim and Korra blocked them.
"Find Magneto!" Korra yelled.
"On it." Vee said rushing off.
Vee into lion form saw Sabertooth before roaring at him.
"This time you can join your pathetic kind!" Creed yelled making vee roar pouncing on him as they fought one another.
Mesmero was rushing through the Museum before he found the second half making him grin.
Only for an elevator to bust through the room before grabbing him making him yell before throwing the other half which seemed to be close enough.
Magneto flew in before Sean did the same.
"What the?" Sean said before they started merging making a green spider.
"Destroy it now!" Magneto said as Apollo blasted it but nothing worked as it just ran off but Magneto tried to hold it down using his powers but it broke free before trashing the place before it left.
"Well, that failed." Apollo said as they went down.
"I don't care what it takes. Destroy that spider." Magneto said.
"I'm gonna go find Mesmero. Odds are he might know how to stop it." Anne said.
"Go." Magneto said as he flew off.
"Shouldn't we let it go? It could lead us to where the door is." Korra said.
"One door has already been opened. We cannot afford another." Magneto said.
"He's got a point. We have to destroy it." Reznov said.
Mesmero was running away before Apollo was in front of him making him gasp.
"Mesmero...I want answers." Apollo said looking deep within his mind as he groaned loudly before Apollo sensed another presence like before but yelled as he was pushed back into a tree making him shake his head before looking seeing he was gone like before.
"Oh you clever jerk." Apollo said.
Everyone was trying to keep the Spider from escaping before Korra did what wan did to vatuu 1000 years ago.
"Thats not gonna hold it for very long. If someone knows how to stop this thing it would be a good time." Korra said.
"Hold it still." Magneto said moving towards it before she let it go as he tried to destroy the Artifact.
"Erik wait!" Charles yelled trying to stop him before he destroyed it before groaning holding the relic as he fell to his knees.
"It's over." Erik said.
"No it isn't. You did exactly what Mesmero wants you to do." Charles said.
"What are you talking about? The Key is destroyed." Erik said.
"It wasn't just a key. It was a safeguard to prevent the final door from opening. And with its destruction...The second gate will now open. He used you. He knew you would destroy it and knew he needed to drag you into this. Thats why he used deathstroke. To get your attention." Apollo said making him growl at that.
"It was heading southeast." Korra said.
"But where was it going?" Sasha asked.
"That is something we're gonna need to find out and soon. Because once he finds the final Key...The world as we know it is going to change." Sean said.
"Apollo, you've been in his mind. Did you see anything?" Magneto said.
"Nothing that made sense. I only know he's nothing but a puppet. This Apocalypse who he serves...His power rivals black Adam or the ghost king. And that is a dangerous thought since I don't think he has the same amount of restraint nor respect for innocent life as I do." Apollo said.
"Maybe we should get the autobots down here. I doubt they will have much trouble with him." Beast said.
"Not yet. Not until we know more." Sean said.
"I agree. Besides...We don't even know where he is and until we do...We would be wasting their time." Magneto said.
the next day at the defenderssanctum.
all the realm defenders were in the main room cause as had something she wanted to tell everyone.

Everyone was surprised and then a portal opened and cleo de nile and frankie stein came out.
Wow that's two surprises in one day Hunter said.
