Pardon my crazy name-calling:
Side Arms(joking), Iron Sides?(another joke)
Hex (hexagon = 6 sides = "six side arms")
Kaligat?
cognate of kali and gat (Kali = 6 armed goddess of chaos/death, and gat=gun)
Mahakala, or some other version
(Buddhist god, six arms, flaying knife, remover of obstacles)
Arachne? (cause spider)
Not sure why I thought up mythological figures, guess it's the six arms.
