I think it would be cool if her grapple attacks in smash, if she got in, were based off the Torture attacks she has in the series.
Down throw would be the
guillotine, the up throw would be that
pulley and chain, forward throw being the
iron maiden, and back throw could be her special grapple from anarchy reigns, performing a series of back flips while holding onto them, and slamming her heels into their stomachs, her heel guns going off, as
confetti shoots up around her.
I always figured her special attacks would be her wicked weaves from the series. Over special could be summoning
Madama Butterflies fist which would punch enemies in front of her, down special summoning
madama's spiked heel to stomp enemies too the ground, her neutral could be to perform the
Break Dance technique, and her up special could be summoning
Mamdama Butterflies wings for a 3rd jump, the attack aspect could be forming a dark aura around them damaging enemies while rising and floating downwards with them still out.
Her normal attacks could just be various different attacks with her guns, yea shes known for wielding multiple weapons, but
I think having her just use her guns would be the best choice, since their the only weapons shes ever seen wielding in cut scenes. I also feel their just more iconic too her character than the swords, whips and ice sates she fights with.
As for her final smash, I dunno, i think Summoning Queen Sheeba would be odd, considering she needed Jeannes help to do so in the end of the first game. I think her activating
Witch Time would be a decent enough final smash, maybe have her summon the
wings of her demon Maphlas, to give her temporary flight during her witch time, as
she did in the trailer. It could function like Warios smash attack, giving her limitless number of jumps while slowing down time to get to her opponents.
