Some cats just dominate over others. Just because they are cats, it doesnt mean they HAVE to get along. He sounds like a 'toufh' cat, the others maybe just dont want to accept him for who he is. I had a female non spayed that didnt get along with a neutered male, there really was no friendship between them, i tried and tried to make them get along by putting them together but nothing changed. they just didnt like eachother. I got the female spayed, still no change. that ends my point.

HOPE THIS WILL HELP
