Or, I could see if I could do it myself, perhaps by creating sprites entirely from scratch (as bases are not my forte).

Just give me the sprite sheets and I'll see what I can do. (No promises, however. I am already overwelmed with lots of different focusses that I want to do.)

That could work too.

Well, Nega-Lime Karjam replaces the Doctor (uncrowned), so he'd be always facing -> , right?
(Nega-Lime's current sprites are 16×24 pixels, while Uncrowned Doctor looks to be 16×32 pixels.)

Nega-Lime Karjam (with the ring) replaces Doctor (crowned), so he'd be facing left? (Although, Aidan Flamberge, from Lunar Shadow, replaces the Crowned Doctor as well, and he faces right instead.) (24×32 pixels.)
His sprites have the markings of Tia and Mat (the red marking around his right eye and green marking around his left eye), and he wears a blue ring on his left hand. (The same ring that allows the wearer to control Tia and Mat. )

He'd probably be a boss as well? (A final one, perhaps~ I should really plan things out.)

Purple Karjam replaces Jenka (16×16 pixels), though.
(The other characters - such as Tia, Mat, Serenity, Shinica, Ilina, Valkyrie, an unknown girl - use the other major NPCs from NpcRegu…)

Although Toroko, Itoh, they aren't replaced yet.

Current NpcRegu for "secret project" Lunar Shadow Imagination (not its real name):
The green-haired girl is unknown at the time, but she was the idea of a flower dragon princess~

… who is currently quoting that The World Ends With You thing a lot more than usual.


Also I seem like I'm getting carried awaaaayyyyyyyyyy~ * blown away, with Charlotte being sent out *
