As you can see, it's based on the Power Miner's Mine Mech. The added parts come Exo-Force for the hands and the additional joints, the rocket legs from Space Police 3, and the arm guards and feet wheels are car parts from the recent Happy Meal Lego Racers. I was always afraid to buy the happy meals because restaurants would never allow kids 12 and up to order of a kid's menu...but McDonald's never questioned me once. There's also a neat little palm blaster on the right hand. On the left hand is a chain-buzzsaw weapon, which is a chain connected to one of those old bionicle heads connected to that magnifying glass piece that holds cross-rods, and is inserted into a cross-holed block under the fingers. The things in the front are also blasters, that shoot lasers in four directions. The silver barrels also shoot missiles if they wanted to :P
The backstory of this mech suit begins, as an old engineer was mining his own business down at the minds in his regulation mech. All of a sudden a bunch of crystal creatures ambushed him and took off with the crystals he dug up. He could hardly catch up with them with the damages and tiny feet. He went back to the base empty handed, as all the other miners laughed at him and suggested he was too old. After the weekend, he came back with a determined smile on his face in what appeared to be a new ride. They asked him how much he spent on the new ride, but were then surprised it cost him nothing and it was just his old mech with new accessories.
Now he was ready for work, and the creatures who threatened his life's work. With deflective arm guards, a buzzsaw chain whip, extra blasters, and rocket boosted wheels he will not only be able to defend himself, but even get a lot more crystal collecting done faster.
I am the God of War!!! Now talk to the hand as you say hello to my leetle friend!!
This design was also inspired a little by Decepticon Long Haul from Transformers ROTF. When I noticed that the Happy Meal Lego Racers were compatible with regular legos, I just had to buy some, and those middle pieces seemed to make great arm guards. As for the "wheel feet", that idea came later. I didn't know want to waste such lame parts, but it turned out well. Now he can skate across the caves, and emulate the freeway fight scene from the first TF movie
