Childre Inarabitta, the Left Ice Judge of the Screaming Interrigation, a member of the Eight Gentle Judges or Weil Numbers in Megaman 3.
Recommended Weights are: 1.0-1.5 (I found it to be more accurate towards 1.5)
Also, I recommend using 'IL Megaman Zero Style Character Design' LoRA by Chamber if you want to make his appearance to that of the game. (Half of the showcase images were made with that LoRA)
