The name is from a scifi movie, I'll give that much of a hint. That is why it's major geek points if you know the movie. For the color there are many variations in different art books. Black was just my largest parts collection and red cause it went well with the black.
I tip my hat to you. This beast of a mech doesn't need a weapon. He can can simply step on minifig mech and squish it with one foot! Sadly, I don't know the Buford part unless you mean Joe Don Baker as sheriff Buford Pusser from "Walking Tall."
What a fantastic build. Itís HUGE!!! The shape and sculpting is excellent. Great transformation process too. I have also made one of these and would like to enter it into the contest. Please could you let me know how and where to enter? Thanks in advance and good luck :D
