Pudding joining with luffy's side

[Blackangel]

this seem like a possibility as she seem to like sanji more and more. i didn't expect him to say her eye is beautiful but that seems to trigger her reactions

 

[Kaname]

Even if she joins, she wouldn't be of much use as she couldn't erase memories of moving people and need to pindown someone before trying her powers.

 

[Blackangel]

but that skill comes in handy. they have many new opponents now and may be they could even battle with kaido with her power alone. it's not a useless skill at all
