>>105512637>Otto stole his fucking body for a year
And Norman messed with peter for a lot longer during the clone saga.
Norman Osborn's feud is so much more personal with peter than Otto's will ever be. Otto just wanted to be better than Spider-Man, but Peter and Norman are practically intertwined at this point, especially now that he remembers who Peter is. Norman Osborn killed his first true love, and has tormented him ever since. He then engineered the entire clone saga, making Peter not sure what was real anymore. His legacy also helped ruin the life of his son, one of Peter's closest friends, and took him away from Peter.
Then he's interfered with even more aspects of Peter's life like buying the daily bugle, putting Flash Thompson in a coma, and then the guy basically took over America during Dark reign, attempting to hunt down Spider-Man and all his other super powered friends.
Doc Ock has only ever really cared about Spider-man. Peter became a secondary thing only during superior.
Norman is obsessed with Peter himself, and that's what makes him Spidey's arch nemesis.
Also consider the following: Otto realized Peter was better than him at the end of superior, and that's not something Norman would ever admit.Also, Otto never fucked Peter's girlfriend (though he did get close)
