DC Comics Joker vs Joker from Flame of Recca
Takuya Kanbara(when he can turns into all Frontier Protagonists' Digimons) vs Homelander
Hiro Nakamura vs DCEU Superman or the Flash(as much as I have nothing against Hiro Nakamura, he can have no match to most speedsters in Fiction, even with his time-stopping powers turned on)
