Concept Wonder vs Capture

I'm trying to make a tag team superhero fighting game. While I'm a bit over my head when it comes to making a Gamemaker tag team fighter that rivals the Vs series, I'm hoping eventually I can have enough proof of concept for a Kickstarter.

Regardless, the game would star public domain characters as seen here with Comet, Spider Queen, Blue Bolt, Black Dragon  and Bombshell. If you know anything about this guys, you know that there's some heavy changes over here, especially Bombshell, who was a young boy and not an enormous woman. But...if you're that big a Bombshell fan to care, you're 90 years old.
