"Only Beast Pirates that matter"
Is a pretty heavy thing to say.
But then I see a bunch of people just Powerscaling.
Okay listen here you little brats!
This might be hard to swallow..
Fighting prowess isn't everything that matters.
Other important Beast Pirates include
Jack
Black Maria
Ulti
And Speed❤ (I'm not a furry I swear)
Okay, for those that haven't disregarded my personal take as the rambling of a somewhat manic individual it actually is.
I'll show you how those Characters are important.
Jack
Jack the first Character ever revealed to have a 1 Billion Bounty, to show the power and unscrupulous methods of the Beast Pirates. He is an important roadblock for the minks and Scabbards to overcome as he brought so much suffering and pain on his search for Raizou.
The Raizou scene is one of the most hitting series of op panels in recent years in which Jack as the antagonist played a major role.
And nothing the minks have achieved as of now would be really rewarding without the backstop Jack shares with them.
Black Maria and Ulti
Black Maria and Ulti had a very strong impact due to showing the personal growth, Nami and Robin had.
With Robin finally being at peace with her role as the demon child she was made to be by the WG if only it is useful to her nakama. (Very much like Chopper becoming a true monster for the Strawhats)
And Nami's first real seemingly unescapable destruction through Ulti where she makes the "Luffy is going to be King of the Pirates" claim for the first time in that way and circumstances. (Reminded me of Usopps fight in Alabasta against Miss Groundhog Day and Mr.4 where he got his face basically pulverized. God I love that fight so much)
Speed
Speed played a major role in turning the tides in the battle of Onigashima by carrying Tama and being a person other gifters would trust when they see her. Also she kinda hot ngl. Lol.
