User blog comment:Matt Hadick/Ultimate Battle Final Round/@comment-3367060-20130711035848

I made a picture with educated guesses and stuff. No bias, no nothing, straigth to the point and including everything. This is a one-on-one battle with no disasters, no allies or anything going, and since the Matrix can only be used at the darkest hour of the Autobots, Optimus (G1) can't use it. It may not be as simple as Godzilla stepping on Optimus or melting him, but there is a clear winner (Godzilla) thanks to his abilities and defenses.

I took the time to be consistent, and if you inspect this picture with an image editor, you can see that it's very exact and that there are no tricks here. The blue Optimus which is around 45 feet tall is the smalles possible Optimus, and the gray Optimus is his biggest possible height. This took me all afternoon so feel free to look at it!
