Sword. When I was a kid, my favourite weapon was Tri Klops's sword. I loved how he had a sheath on his back, which together made him my favourite of the villains at the time. I still hold Triklops in the top tier because of that sword and sword sheath on his back.
Was so glad 200x made him so important.
Plus his sword was long and thin and looked more like what I thought a sword should look like.
