You're probably spot-on...

but apart from the characters you mentioned, Annie could be pretty fearsome when she grows up, and Cho'Gath is hinted at to be ridiculously powerful as well.

Nasus, Renekton, Kayle and Morgana are either just "ordinary" League-tier superhuman or genuinely divine in terms of power.

I'm unsure about Eternum Nocturne...
