Green Lantern brought his ship construct up next to the alien mothership, putting one side against the ship and dropping that wall. Martian Manhunter used some eye beams to cut a hole into the ship. There is now a way inside.

"All right," said Levi.  "I'm going in."

...Were the others tougher than her?  It was possible, but unlikely.  She'd been carefully made to survive just about anything, so she took the lead.

The others followed.

"Give me a sec, I'm going to weld this back," Green Lantern said.

"All right," said Levi.  "Be on guard, everyone.  We don't know what the capabilities of their ordinary soldiers and weapons are... I'll see if I can figure anything out..."

She looked around, with both eyes and sonar, to see what she could of their environments and the threats that might surround them.

You can sense about thirty to thirty-five of the various types of aliens you and the others have fought.

"...Okay, this could be rough," said Levi.  "There's nearly three dozen of them, and they could all be pretty powerful.  Let's try and set up a bottleneck so they can't all get at us at once."

She tried to find a good place for a tactical advantage... it was hard to be sure what some of them could really do, though.  Maybe Batman would help explain himself eventually.  Oh, and the fast one...

"Flash, can you see if you can find the ship's engine room or control room?" she asked.  "If we can damage the ship a bit, they might have no choice but to retreat."

"Sure thing!" Flash said, running off. "Found it."

The voice was coming from behind you.

"Probably going to need somebody much stronger to damage it and I can't read what's written on the signs or keyboards."

"Oooh, that looks like a job for me," said Levi.  "I'm good with languages and strong, too.  Let's go, team!"

She moved in the direction the Flash had indicated.

The Flash leads you and Batman to the engine room while the others run distraction. Warning lights and sirens are blaring as you arrive. The consoles are really high. The signs posted were mostly safety signs and what not to do. You now know what buttons you should totally not hit.

"Okay, get ready," said Levi.  "They're coming... I might have to take their ship hostage."

She ripped the cover off a non-vital control in an effort to make the threat she held clear to the approaching aliens.

Soon, a couple of the rocky aliens appeared, shouting things

"What are you doing, small things," one of them demanded.

"Greetings to you," said Levi.  "I'm preparing to cripple or destroy your ship.  You have threatened the peace and welfare of our world, and this is not acceptable.  Your candidates for kingship are defeated; you will not be allowed to threaten us.  Does that answer your question?"

"This will not stand," the alien said.

"Why?" asked Levi.  "What gives you the right to destroy our cities to solve your own political crisis?  If the only thing that gives you that right is power, please consider that we ourselves have defeated your candidates for kingship; I myself struck down four of them.  Further, if power is all that defines right... I am currently in a position to destroy your ship entirely.  That gives me power over you.  Does that make it right for me to kill all of you?  Consider your answer carefully."

"Damned, small thing," the alien said as some sort of speaker came on.

"Attention Appellaxians, this is Hal Jordan of the Green Lantern Corps. I, along with other Earthlings (and a Martian) have infiltrated your ship and are now in control of it. You have violated several treaties and must immediately withdraw or face retaliation under the law."

The alien began to massage their head.

"Damn it all! We surrender..."

"...well, that works, too," said Levi.  "Okay.  You guys take your fallen king-candidates and get out of here."

"Fine, you small things have won," the alien said, calling the other ones off.

"Good thing you happened to speak space alien," Flash said.

"Yeah, but I think the Lantern and the Martian can, too.  I mean, the Martian's a telepath," Levi pointed out.  "Still, it worked, and that's what's important."

"We should take our leave," Batman said.

"Well, yeah, obviously," said Levi.  "Let's get going."

"We'll take first class out of the airlock this time," Green Lantern said as you showed up. "Space submarine for the lady?"

There was now a large green energy sub sitting there with a ladder.

"...well, I guess?" said Levi, entering it.  "I've actually never spent time inside a sub in my entire life."

She'd never needed to.

Aquaman just gave Green Lantern a look as he got in and sat beside you.

"Air breathers," Arthur said to you.

"Well, he tried, I guess," said Levi.  "...hey, sometime soon, I need to talk to you about something.  Lex Luthor tried to do a stupid thing for cheap revenge that has the potential to cause a mass extinction event down the road.  I don't know if it will, but it's going to hit you first if it does.  We should talk about that."

"Certainly, whenever you're ready," Arthur said as Wonder Woman climbed in followed by Flash and the Martian Manhunter. Batman brought up the rear and soon you were back on Earth outside of Gotham.
