Those are the komato fiends, they are armed with karambits instead of fireweapons to better fight in envirovments where explosions of fire would be dangerous.

I created for each bodytype 2 separated sets, one with the karambits and one without the karambits, to allow the creations of many different monsters, hostile, ally, fleeing, friendly or as background decorations.

About the bodytype, i tried to narrow the selection, but i'm confident who might want to create only one rank/monster will find an appealing bodytype, and who might want to create several ranks or a background scene can give variety to their evil army.

There is a mistake in the 02 Tall Male. i forgot to render the SW sprite, so in that rank they were obtained mirroring the SE sprite, of course in those cels the hatchet is strapped to the left thigh... It shouldn't be a big deal, perhaps in future i'll create another huge male.

For now, Happy New Year!

In the second last preview image you can see the suggested absolute size of the respective bodytypes, altough is just a matter of drawing scale (anyone can imagine and code them as mouse-sized or skyscraper size)
Small male and petite female should be compatible with the original game Iji by Daniel Remar.

In the last preview image i'm illustrating the possibility of create several ranks by swapping palette, and temporary or permanent "auras" that can be combined with auras from various game engines, creativity is the limit, but all those auras can be created with few clicks on an entire spritesheet, i doodled them in a couple minutes, let me know in the comments if you are curious about how to add such auras on other spritesheet.
