I mean like a full on chapter war, like rivalries turned way too hot and they decided on a death duel with full weapons and armor. I think sicarius would go first due to him being way to prideful. I am not doubting his prowess, I mean going toe-to-toe with a necron overlord and not dying in the process is phenomanal, but he will probably try to go face all of them at once and just get obliterated. Belial fought against ghazkull and lived which I think is way tougher than blue boy. Darnarth is an extremely close second and Kayvaan is also close. But Blackmane and Cato are both outclassed, no matter how good their battle prowess is.
