Brody and Shade have the same power. They even have the same power when not flinging. They're both able to turn into smoke/invisible and invincible anytime they want and stay that way however long they want, and they can both fly. The few differences between Brody and Shade is that instead of activating his ability upon contact with the ground, Brody just turns to normal instead; Brody can control wind and smoke freely, and Brody needs to turn into smoke (at least mostly) to fly. Also, Shade vector inside.
