Been sitting on lots of fodder and decided to try to see how many different pieces I could combine to make a feasible figure. I had a SW Clone tank lying around and started with it. After adding pieces and parts from Gundam, Roadbots, GI Joe, and various other toy lines I came up with a Cybertron Mode Slag. I felt that the stocky frame fit Slag well and it seemed to go well with the scale of FOC Grimlock.

Head - Combiner head from RID Wedge
Body - SW Clone Tank
Missle Pod - Military Set
Shot Gun - GI Joe
Sword - Roadbots
Flame Thrower - Lex Luthor Movie Figure
Shield - Gundam Wing Shield & Power Rangers spikes

As always thanks for looking,
Shinobi
