Evano, you've delibrately ignored my points on why Amos is the main antagonist. He's perhaps not the main villain, but he is the main antagonist; he's the primary opposing force to Tod and the instigator of several conflicts, most notably the separation between Tod and Copper. The bear only appears at the end and doesn't have any outside role aside from that.
I'm not banning you, I'm not warning you for anything, and I'm only locking the page after this. But since you so clearly seem to refuse to distinct between an antagonist's role in the story, I'm messaging you now so perhaps you could refrain from doing that later.
I'm sorry, it won't happen again but the unseen hunters at the beginning are the main antagonists because they are why Widow Tweed adapted Tod which led her to tell him to go out and play and he became friends with Copper which led him to go onto his property and Amos saw him and tried to shoot him when he first saw him which led them to be seperated. This would reduce Amos to be the secondary antagonist.
