Henry is a male (obviously) he is some bizarre hybrid of human and tarantula. I have no idea as to why people would mix some one, but does every one needs a back story? Anyways Henry may try and look bad ass and confident, but he is actually very insecure. He is sensitive, and a drama queen.
Now about the pictures.
1: This is just a side few of Henry's head. He has blue hair with dark blue coon striped side burny things. He has large grey fangs on his face. And he has large often open wide pink swirled eyes.

2: A shot of Henry's back. It's supposed to give an idea on his back arm placement. As you can tell he has 8 on his back

3: The cat is named Charlie (Mig's real life cat) He is Henry's best friend. And the envelope is there because that is Henry's biggest fear. He is stupidly scared of them for no real reason.

4: A full body picture of Henry. As you can see Henry has 12 limbs in total. Yes he is a cluttered mess but he is my cluttered mess.
