I don't have these toys currently; they were two of my favorite action figures when I was a kid. I bought them at a flea market and I thought it would be fun to look for these or others in whatever series again but I have no idea what they were.
There were two. Both were yellow hard plastic (but I'm almost certain hollow,) had only one "moving" part which was their waist which could rotate, and were around 6 inches tall.
The first one was ogre-like with pointy cat ears and a cat mouth, fists which stuck out to its sides, and a tail with two spikes. Slightly lumpy texture. Accented with blue paint.
The second was bird-like with red "hair," a beak with little teeth, and stubby wings and feet with silver claws. Partially scaled/feathered texture. I don't remember its tail or if it had one. Accented with red and silver paint.
I can find similar styled kaiju toys made by Bullmark but I don't see these in their collection, maybe a knockoff?
Sorry for the drawings, I'm not an artist but thought they might jog someone's memory.
