All fighters from Rocky 1-6 ranked(I explain why below)
I rewatched all the Rocky movies recenlty so here is a tierlist of all fighters.I'm gonna make with the fighters from Creed movies too.
S TIER -- Thunderlips,Rocky Balboa,Ivan Drago -- Ik Thunderlips is a wrestler but his size brings him here.If a guy who's 2.01m tall and weights 177kg really wants fight you then you are absolutely cooked.His fight against Rocky was for fun so i can't take it seriously.
Rocky Balboa (prime Rocky from Rocky 4) -- He is the perfect fighter.A brawler who can hit well with both of his hands,has crazy endurance,heart and physically at his peak.Rocky from the other movies wouldn't beat Drago.
Ivan Drago -- the final boss of the Rocky franchise.His strength and his endurance are in a crazy level.A fight between him and Clubber i think it would be like this https://youtu.be/8AfGCRT1JdU?si=Ul-2lwlpn9fClX2m
A TIER -- Apollo Creed -- His fighting style is the most difficult to cope and to achieve it you have to be athletic af.The only bad thing about him is his pride(too confident where he shouldn't be) and his lack of strength.He can beat Clubber ( the reason is here: https://youtu.be/ZDQjqM8ktH8?si=soI3Kj5V4JOEBsbD) but not the fighters above him because of his disadvantages(Not even in his prime).
B TIER -- Clubber Lang -- Ngl my fav character in the whole franchise.He is strong as hell and his character made him even more dangerous opponent.His lack of strategy and endurance is the reason why i he can't beat Apollo or Drago and prime Rocky.He wins easily though everyone below him
C TIER -- Mason Dixon -- The most difficult fighter to rank.In terms of skills he's quite balanced,he isn't too strong or fast but totally he is on a decent level.I ranked him above Tommy because he did much better in his career
D TIER -- Tommy Gunn,Union Cane -- Tommy is quite strong,he learned some skills from Rocky but he was mentally weak and his opponents weren't something special.He lost in a street fight from an untrained Rocky who had a brain injury.He won against Cane but i think that fight was rigged.Cane didn't even try to do something.
Cane was the champ for some years but he was a paper champ.Not something serious
E TIER -- Spider Rico -- Nothing to say here he was the worst fighter in the whole franchise
