MEGA bro-mon like pokemon

What if bro-mon could have like a mega form like in Pokemon. you would have the option to switch between them in the extension but you would have to beat boss erosions to unlock them. some mons that could be mega are-
Every legend
Every mythic
burger turtle
and dapper squid-becuase yes

YESSSS THAT WOULD BE BRILLIANT! because you could like store and care a bro mon could evole but what would the best form be? like yk catnap he could have his final form monster catnap

but he’s already in his monster form

also I made a diffrent post about bro-mon evolving sepretly about a week ago
