Classic Thanos vs Superman, Black Adam, and Gladiator...
Superman, Black Adam, and Gladiator are all dual weilding primary Adamantium Katana's; other than superspeed, their natural strength, and flight, they cant use any of their other powers or abilities...
Classic Thanos (pre AoD) can not use any of his tech or powers; he can only use brute force strength...
Battle to the Death or KO in the middle of the Sahara Desert...no BFR...who wins?
