Boxing/fighting muscle importance

[SoupNaziNazi]

I'm aware that being well rounded and having a strong muscular body is best for being the best boxer/fighter you can be. Want to know people's thoughts on importance of certain muscles over others. Such as if you could only pick one muscle group to train to be a better fighter what would it be? Looking for responses along the lines of top 3-5 muscles in order of importance. I've been out of the game awhile but my soft list would be;
1) shoulders(specifically front delt)
2)back(specifically lats)
3)legs
Focus is on punching/stopping power and being able to dominate someone with brute force(I know technique is a lot but that's not what I'm asking here)

1) Core
2) Legs
3) Core

You drive your punch with your legs and pop with your core. Defense is lots of core movement and support. Grappling relies on leg strength for under hooks, stability while on defense, and ability to drive a takedown or hold half gaurd.

Anything besides legs and core is just for overall performance. Those 2 are what will increase power. Delts and back and chest and everything else OBVIOUSLY need to be conditioned, that's just for overall muscle fatigue.

Cheers mate, I appreciate your input. Definitely want to focus more on leg strength
