Just something for an RPG type thing, a human character of mine... I haven't worked it out in detail, but he has a boar tattooed on his right shoulder blade-- it's kind of leaping forward and is full of spears and arrows. Just drew this to show the placement. I like the idea enough that it's going into my bank of possible tattoo ideas for myself.
He also has a snake, a pit viper of some sort I think, on his left arm.
