On a number of worlds throughout the multiverse, a series of strange devices suddenly appeared. Initially, they looked like gold-framed mirrors, floating a few inches off the ground. After a few seconds, the "glass" changed to display a city in flames. A trio of voices called out from the devices, begging for people to step through and help against an alien menace which had arrived on their world and was making quick work of their armed forces.
 
The calls to save them from death or slavery, the promises of rewards for any who helped and the fact that without help, there would be an army with conquest in mind and multiversal portal technology in their hands served as good motivation for a number of allies to arrive. Unfortunately, the voices had left out an important detail: Opening the portal network on this scale was a large strain on the system and a number of important components were fried in the process. In order to it running at peak performance again, they will need to repair the portal generator with parts from other worlds. With their new assistants' help, of course.

So, basically this is a multiversal crossover where the characters will need to travel to assorted worlds in order to gather parts to repair the portal device that will get them home. Well, after saving the world they agreed to help in the first place, at least. While this is intended to be a crossover, OCs are allowed.
 
While I'm not expecting everyone to be identical in terms of ability, I will reject characters that are too powerful...or too weak. After all, it wouldn't really make sense to call in someone with the power of "gun" to deal with technologically advanced alien invaders, and if someone can single-handedly wipe out any threat they face, it can leave the rest of the cast feeling redundant.

There's a limit of 3 characters per person.

If anyone has any questions about the RP, I'd be happy to answer them. And with all that out of the way, here's the character sheet:
