Cosmic Garou, neg diff

Narutoverse because of hax:

(Kamui, izanagi, kotoamatsukami, infinite tsukoyomi, etc)

Hate to break it to you but cosmic garou can literally destroy universes everyone's dead by the time they find out they're even fighting someone

By the time madara tries to unleash his rinnesharingan, garou would have killed him

Yes

Itachi uses his genjutsu and Kakashi kamuis his head off

Garou will just dodge kakashi’s kamui. Also garou has no chakra
