Advice on how to stop a rooster from being mean?

I took a minute long video explaining the situation, but 40 second got cut out. Essentially I’m covered in scars thanks to him. He only attacks in bratty ways and he knows he shouldn’t because after an attack he’ll usually run away but lately his attacks aren’t just a quick bite, but a grab and pull trying to tear my flesh from me. It often happens when I casually lean down to give him a pat or if I try to walk away from him. He follows me around endlessly and he does like gentle touch and pets, but he’s being a mean brat.
When he bit me a second ago, I didn’t get to show it in the video, but it’s a big swollen blood blister on my arm. I pinned him to the ground. I can carry him around without worrying about him biting me or my face but he’s a heavy bird and it causes him to pant when I carry him so I don’t do it for very long cause I don’t want to make him uncomfortable in a painful way.
Any advice on how to deal with the situation and get him to be a little less mean?
Also turning him into stew is not an option. I’ve spent thousands on this bird in vet visits alone and specialty care. All of my birds are special needs rescues and I would never eat them. I don’t even like poultry meat never have so I would appreciate it if people didn’t tell me to eat him.
