I think Starshine and Dermont have a decent amount to mesh about. Geeks who are good people but struggle socially. Though they are definitely different kinds of dorks. One's a geek and the other is a nerd! Dynamo might help bring out that bubbly personality she has online into her everyday life, though!

Sleet and Vector have similar upbringings but seem like very different people. I'm excited for Dermont to maybe find out that Vector helped support him and others like him, especially if, up until that point, he just sees Vector as an uptight rich kid with a fancy gun. 

Butterfly could be a cool one for everyone, since she's most likely to figure out things about the others. Maybe she figures out Dermont has a sword talking to him? Or how many wealthy and famous people are in this team, hahaha!
