Response to 20 Superheroes With Useless Powers:
Most of these “Legion” affiliated characters actually didn’t make it. Matter-Eater Lad and Bouncing Boy are/were members, but Color Kid, Stone Boy, and Rainbow Girl are subs and Arm-Fall-Off-Boy didn’t even get that far. They all exist BECAUSE their powers are a bit lame. Even BB’s origin comic way back when was about how his power seemed silly but because of his intelligence and ingenuity, it’s actually very useful.
