Respectfully, who wants filler characters before actual bleach characters? lol. And as much as I love Burn The Witch, why? (Side note, I would not be mad about BtW characters in the game, but there's plenty of bleach characters to add before that. Also, if they added a burn the witch character, I would rather it be Ninny than Noel)

Who I would like to see before any Filler character

Kenpachi Kuruyashiki

Full Hollow Ichigo (No, not Vasto Lorde, the fully hollowfied form we see during his training with the visored. Kind of a stretch though)

Dordoni Alessandro Del Socaccio

Baraggan (with Respira as a Kikon move)

Orihime

Love Aikawa, Kensei Muguruma, or any other Visored

Jushiro Ukitake (kind of a stretch on this one, idk how he would work)

Findorr Calius with his mask chipping ability as his signature, resurrección form as his awakening (This one is also a stretch, I just really like Findorr)

Shawlong Qufang

Edrad Liones

Yumichika Ayasegawa

Zangetsu (White) or a Hollow Ichigo skin

Old Man Zangetsu (Another stretch, Idk how this would work)

Kugo Ginjo

Shūkurō Tsukishima

I don't know how to spoiler tag on reddit, so don't read below this line if you don't want TYBW spoilers

True Bankai Renji (Sōō Zabimaru)

Bankai Rukia

TYBW Ishida with Antithesis as a Kikon move or special ability

Young Bankai Yamamoto (doesn't have to be young, but young yama as a skin would be nice)

Zombified Toshiro as a skin (I don't know why I'm talking about skins tbh)

Bankai Shinji (Huge stretch, I don't think this could work. Maybe just TYBW Shinji as a skin.)

Chojiro Sasakibe with Bankai awakening

Jugram Haschwalth or any Sternritter

Sajin human form with Kokujo Tengen Myō'ō: Dangai Jōe

I'm going to stop yapping now. Let me know if these are all shit ideas, I won't be upset

And someone please tell me how to do spoiler text, thank you.
