I made Monkeywrench to be part of my own custom Dreadnok 5 pack. I had Zartan, Buzzer, Ripper, and Torch already but needed a fifth Dreadnok. I had already made custom 25th Anniversary versions of Zarana and Zandar, so I needed another Dreadnok. I decided on the fourth Dreadnok to join the team (via the cartoon), Monkeywrench. I (as do many) feel that Monkeywrench is the true fourth Dreadnok.
I never liked the weird harpoon gun that the original came with. Since Monkeywrench is a demolition expert, I felt he should be using a grenade launcher. Instead of carrying five of the same greandes, Monkeywrench now has two anti-personal grenades, two anti-tank grenade (those are the larger ones), several rounds for the grenade launcher, and a satchel explosive. His side arm is a colt .45 magnum automatic pistol.
