Grimsword is an evil knight from the 80's Advanced Dungeons & Dragons toyline. His armor and weapons are decorated in a snake motif. Grimsword has articulation at the head, shoulders, and hips. He has a built in action feature that allows him to swing a sword. This feature is activated through a button on his side that looks like a snake's tail.
Grimsword originally came with a sword, morning-star, and shield. All his accessories were decorated in a snake motif. I bought him at a yard sale when I was in Middle School. I used to equip him with an orange plastic sandwich sword. You know the plastic swords you use to hold a sandwich together or spear an olive. I had a ton of those swords as a kid.
