At the moment, it's a pretty basic idea since many of the character details would have to be worked out (powers, costumes, etc.) once discussion began.
Synopsis: Your character is a superhero, and mine is a teen trap superhero or his sidekick.
One idea involves your hero deciding that it's time to train a sidekick. My character is elated that the hero has chosen him. However, when the hero unveils the costume for the sidekick... it's clearly a female costume!
There is plenty we can discuss. Please send me a PM if you're interested!
