So I just thought of this idea....Yu-Gi-Oh monsters. Like the Blue Eyes White Dragon, Red Eyes Black Dragon, Dark Magician, and the other various monsters they have.

But I'm no modder. What you guys think?

.... Do you mean summoning them to fight beside you? If so that would be pretty cool. Not a fan of Yu-Gi-Oh but i do like the art direction for many of their creatures. And with a little tweaking could become semi lore friendly.
