Those animations were made some time ago for an old school 2D side scroller project with N.E.S.-like graphics.
Plot: In a civil war between hight-tech unionists and vodoo confederates, a confederate officer find out that both sides are planning the resurrection of both demons to help them conquer the world and decides to put an end to their mad plans. | 
Thanks! I'm happy with the character design, but had problems animating it at 3 frames. The walking cycle needs to be redone, but I wasn't able to it right. Maybe some day I'll try again.
