So I've been thinking of adding a male character. I just don't know who.
I have a teleporter, the twins (one's superspeed, the other telekintectic - but the boys have a younger sister and that's too many characters so maybe not that clan), one that does geokinesis (earth/ground control), one that has powers like Rogue from the XMen, one that has lightning/thunder/storm powers (though then I might be obligated to include his girlfriend as well), and one that has ice powers. 

Plus some others that are still in the works.

I would just add Julia's bro, but he doesn't have powers.
