Leaning just right. The dude fought against:
Wave 1: 9 Scabbards, who made him bleed and reopened his scar to some extent
Wave 2: Supernovas, who beat him around and attacked his innards
Wave 3: Hao Infusion Luffy
Wave 4: Yamato
Wave 5: Luffy again
Wave 6: Gear 5 Luffy
To put a little more detail into it, it was:
Wave 1: A surprise attack from 8 guys he thought he killed or imprisoned decades ago, who were later joined by one of the Whitebeard Pirates' commanders
Wave 2: A 2v5 against guys who all had prior knowledge, all of whom were supernovas, including 3 guys he previously beat up and sent to Udon Prison(He's gonna have a long talk with Queen after this), one of whom was intentionally poisoned with a SMILE to make sure this exact thing didn't happen, one of whom was a former Warlord, and... IS THAT ENMA?!
Wave 3: One of those dead swordsmen he beat up earlier. Does this guy really think he can win here?
Wave 4: His own son, who was supposed to be in Seastone cuffs with the Tobiroppo hunting him down.
Wave 5: His son again, now teamed up with one of those Supernovas from earlier, and... WHY IS THERE ANOTHER DRAGON??
Wave 6: A final 1v1 against Luffy, where he literally just murders him and throws him off Onigashima.
Wave 7: He generally just flies around beating the shit out of everyone he sees, firing Boro Breaths at anyone who talks shit.
Wave 8: This Little Dragons Jr guy he's never seen before starts talking to himself about telepathic elephants, and he hears a bunch of drums playing... is that like a theme song? Is that... is that boss music? WHY IS THAT GUY STILL ALIVE??!! WHAT IS HAPPENING HERE??!!
And then it ends in a draw.
