Daidouji (Senran Kagura)

&

Colonel Alexander Louis Armstrong (Fullmetal Alchemist)

VS

Dio Brando (JoJo's Bizarre Adventures)

&

Senator Armstrong (Metal Gear Rising)

Reason: It's a bunch of anime muscle people fighting. Why wouldn't this be awesome. And before any of you begin to say that Dio would win, I would like to inform you that Daidouji managed to punch TIME... let that sink in.
