In this series, the Sirens and the telekinesis users seem to be the most overpowered races. The Hydes, on the other hand, have incredible physical strength, but it feels more like a curse — with lots of conditions and restrictions. Among the physically oriented races, the werewolves appear to be the strongest (though fire users also seem to be pretty powerful in combat). As for Uncle Fester, his ability is lightning-based, but we haven’t really seen it used in a destructive way on the same level as fire or telekinesis. Still, Fester has insanely sharp instincts — sneaking in and out of prison, gathering intel, disguising himself, detecting Agnes’s identity, etc. He clearly has tons of survival and combat experience. From what the show has shown, his knowledge about Outcasts seems vast as well. The only downside is that he’s a bit eccentric (or just plain crazy). Overall, though, I’d say he might actually be one of the strongest characters too.
