Your PE proposal for Akumaro Sujigarano will be a freebie in regards to this topic since he is under the category. But for future reference, please ignore users who demand requests for PE proposals, especially if they haven't edited on the Wiki at all. The reason I say this is because Radiant Accuser, the user that asked you to make this proposal, is a sockpuppet of Lady Satsuki, a cross-wiki problem user who tries to dictate whoever is or isn't PE in her eyes and responds to anyone who doesn't agree with her with insults and vandalism. She's clearly trying to find a loophole to push candidates through without actually touching the Wiki, which won't work at all. Just keep this in mind for the future.
Umm... There's Hiroshi Tennoji and Isaka from Blade. Though Tennoji has a different goal from Isaka. Kiyoto Maki from OOO, Tatsumori Yamada from Fourze. I guess I will leave it to you in doing a proposal for Tennoji, Isaka, and Dr. Maki. Sometime tomorrow, I'll do Sora Takigawa/Gremlin from Wizard.
I suggest that you ask the admins for approval. Because, they have the capacity to do so. For some reason, we all know Drakkon managed to surpass 2017!Rita Repulsa as one of the Power Rangers franchise's most evil villains.
