Yes, Strike Back is used, but it's a Leader Ability that doesn't have the same effect as King of Squid described. If he changed the name to something else, I'd enjoy it. It would be the exact opposite of Courage.
How about using composure rather than defend?
Maybe the clan is related to justice?
Since the 3 clans involved in the comics were monsters (the nightmare clan are monsters right?), pirates (which steal from ships and stuffs) and a mafia (well it's self explainatory. lol)
@Errare But they also beat up Harrow Ld.
My guess is that beating up Harrow Ld was to establish the backstory of that clan being just your average wrestling federation and not righters of wrongs. If it is a new clan.
If he can easily defeat Montana, I think that this clan's bonus could be Protectionower or something. With Piranas, he challenges them because their bonus does nothing to him, and Uppers is just like Montana. Just thinking...
