Her combat abilities (especially her electric powers) are pretty interesting IMO. Plus it'd be nice for the crew to have a female that's a front-line fighter since both Nami and Robin are usually just support.
She obviously needs to get a backstory and some kind of goal, but I wouldn't really say she's just a female Chopper.
Uhhh interesting how? Mink's electro is a poor man's version of Enel's ability with less application. Not to mention how characters are already tanking it. What is so cool about her electric punch that elevates it over the dude with the exploding punch, the dude with the nuke punch and the dude with the giant punch who are already SH Fleet members? Her most interesting ability is her agility/floatyness imo anyway
personality wise she really is just female chopper.
- has the wide eyed childlike personality of chopper
- Only motivation in her backstory so far is that she wants to see the world. Chopper's was similar but deeper
- both have a goofy/cutsey vibe in their interactions
-Both are the type to get scared of menacing enemies. Both have weakling trio affinity even though they can hold their own abilitywise. Up there with Usopp and Nami as most likely to get captured by a lower ranking character.
-Both love sweets
They're so alike I think it by itself guarantees she wont be a full time SH
katakuri won every encounter so far stop it ya boy cnt one v one for shyt...yet.
ZoGAWD one shotted Arlong knockoff 2.0 and it took luffy almost the whole arc to do so
