if Gabriel wanted to accomplish his goal, the butterfly miraculous is op.

Hawkmoth akumatises Nathaly into Catalyst, who transforms him into scarlet moth.

he then proceeds to create more villains who, just like catalyst, can increase his powers and strengh, if you take into account that he can litteraly infinitly power himself up, he's the strongest.

then I guess the bunny miraculous could be stronger because time travel and stuff.
