As the title suggests, this was commissioned by blackwing2, and he just wanted me to come up with a design for the most, "Metal" tyrannosaurus rex I could think of. This is what I managed to come up with.
*Sniff* It's... It's beautiful. ;w; Those metal bones, those skulls, the toxic plasma canon, that flamethrower, that tail scythe, those damn pipeline-guts, EVERYTHING... You, sir, have created the most beautiful war machine. X3
