Going with a classic here for Voxel Mech Head 2. Here is the RX-78-2 Gundam from the original Mobile Suite Gundam.
This prototype Mobile Suit was created by the Earth Federation Forces on Side 7 in UC 0079. Amuro Ray piloted the RX-78-2 Gundam in the One Year War against the Principality of Zeon. It would be one of the first Mobile Suits to make use of Beam Weaponry. It also served as the basis for Mass Production of the RGM-79 GM.
Since my recently renewed interest in Gundam and Gunpla, I have come to realize that I am primarily a fan of anything from the original Universal Century. I seem to care more about it's designs and I think it is because of the amount of detail packed into the UC Timeline. There is extensive information about the history and construction of each Mobile Suit model. There is also comprehensive data on almost all combat operations during each point in the timeline. Love me some Gundam!
