Crawler

He’s sort of a special case and is a combination of two fears. Spiders and weapons. He may not look very spider-like, but he has spider-like abilities, like the ability to produce venom and webs produce webs, and he also has spider legs that grow out of his back. Crawler may not physically be a weapon, but he has an insane amount of knowledge about weapons and can make weapons out of anything. Because of this, he works as a weapon crafter and makes weapons for monster hunters.
