Okay most of the pieces are characters are coming into place and I'm getting a good idea of the plot. There are just some more characters that I need for this to fall into place.

First of all I need more Asian heroes. I've got China, Japan and Vietnam pretty clear and an idea for Hong Kong is blooming, but I'm still going to need ideas for Korea, Taiwan, and Thailand.

Secondly there's Liechtenstein. She should have something that's both powerful yet easy exploitable, for plot related reasons.

Lastly I would like some ideas for South American and African OCs. It's not necessary, but I'm interested to her what you guys have to say on the matter

... of himself. Like Ben 10's Echo Echo, or Dr. Maddox from Marvel, or Naruto's Kage Bunshin no Jutsu. Since she is often partitioned by Russia, lol.

I say Lithuania should have shadow-striking as his main power, that is he can teleport strikes unexpectedly. Based on a major victory against Prussia during the Teutonic Crusades.

Denmark is a berserker, he doesn't need any superpower. He has a long axe and is well-trained with it.

Sweden can be a great strategist and engineer, close to Tony Stark, because Ikea.

What can you do with France? For one thing, he is an excellent fighter, but charges unthinkingly to his target, allowing him to be defeated often. Ask England.

If you didn't do this already, how about shapeshifting? He could totally use it to spy on their enemies and/or freak out his teammates.

(Also, keep in mind that America's canonical Super Strength means he doesn't necessarily need more powers. I bet the whole superhero thing was his idea anyway :P)
