Hey Yenn , Itora and Ashend! If you hate soulus so much why don't you kill him? I mean you three are practically untouchable, Cyclone needs you and the rest of the army is to afraid of you three to do anything! So what's holding you back?
“Cyclone. That’s why.”
Cyclone’s Forbidden Attack is at a much stronger stage than any of theirs. He wouldn’t find it hard to kill them, and he would definitely kill them if they seriously harmed or killed Solus. Then he would have their Forbidden Attacks ‘transferred’ to other pokemon. He needs the Forbidden Attacks more than he needs them, after all.
I didn’t include Yenn in this ask since he is no longer part of Cyclone’s army. If you want to know the yanmega’s opinion on things like this, ask Yenn directly.
