This is actually not about a character, but I'll tell you the things I know
===================================================
The white mogeko in the middle (and also sweating), is General Hashasky from Russia.

The other Russian mogeko that looks like Moge-ko is Mogek-ov Hashasky (she's quite calm).

In this game, Yonaka became Lord Prosciutto and resurrected Nega Mogeko (defect Mogeko).

General Hashasky was kidnapped by Moge-ko all the way from Russia.

Gen. Hashasky was made 'a toy' by Moge-ko and was released from his cell by normal Yonaka and defect mogeko.

Moge-kov Hashasky fought Moge-ko (I think) in a scene in the game.

Please see the video.
