The Maestro VS:
-Thanos
-The Destroyer
-Kurse
-Loki
-Superman (normal, no super-speed)
-Doomsday (no super-speed)
-Thor w/ power belt, power gauntlets and warrior madness
-Wonder Woman in armor and with sword (no lasso or super-speed, and the Maestro knows the sword can hurt him...though IMO maybe it can't because even tho it cut Superman might've been because he's weak to magic)
-Darkseid (post-Crisis but not loser version, no OE)
-The Juggernaut (keep in mind he was once hurt by punches from Merged Hulk in TIH #404...I saw the pics)
-Hercules (immortal, and he has adamantine/adamantite mace)
-The Absorbing Man (he's absorbed adamantium)
-the Superfriends version of Aquaman (yes, I'm a mean bugger)
-Every member of Alpha Flight put together (the Hulk IIRC once wrecked all the Avengers at once, so maybe this isn't just an automatic "curbstomp" in AF's favour)
-DC Ares
-Gladiator (this can't be a total instant victory for Gladiator...IIRC the Hulk has given him trouble before)
-Beta Ray Bill
-Sersi
-Zeus (physical combat only, no thunderbolts or blasts of energy)
-Odin (physical combat only, no magic or energy blasts)
-1,000 average Asgardians
I may think of more later.
