The consortium of evil, Dakkar is an alliance of villains, intent on conquering or destroying the universe. Ruled over by a man known only as "L", the organisation's various members are more or less free to pursue their own agendas. Through "L"'s leadership and the access a number of groups' resources (though generally, they still keep more advanced things to themselves), Dakkar has already taken over a large number of worlds. And now, they turn their eye to Earth.
 
Isla Tranquila, an island resort off the coast of South America that attracts people from around the world. With beautiful beaches, a variety of caves, lush greenery and a large mountain, in fact a dormant volcano, the island has attractions for a variety of people.
 
Unfortunately, these same attractions that bring in people on holidays have also drawn the attention of some of the invaders. Fortunately, Dakkar is not the only force active in the universe. The Galactic Union Police oppose them when they can, and while they're too caught up fighting on multiple fronts to spare many agents to protect the Earth, they have sent what they can to help them fight back.

So basically, this is...kind of a crossover. Kind of. The idea is that the PCs (or most of them at least) are more or less normal people from a more or less normal Earth holidaying on a tropical island. The forces of evil (made up mostly of an assortment of villains from various works of fiction) attack and a couple of representatives of the forces of justice (again, made up mostly of fictional characters) show up to hand out equipment and/or powers (which would take the form of cards with the original owners' picture on them) to them.

From there, the players will continue defending against the invaders, though there will be downtime for interaction and non-combat shenanigans in between attacks. Depending on how things go, the players may end up taking the fight to the villains, trying to kick them off of other worlds.

Brief Backstory: Again, at least a couple of sentences would be appreciated.
