If i were to compare the 2 what would be bigger and taller? Also who do you think would win in a fight?

I think someone did a "vs." video with these two and posted it on YouTube years ago. Liberty Prime owned the behemoth - wasn't even close to a fair fight.

Are you serious? Optimus Prime is something like three stories tall and throws nukes and has laser eyes.

A Behemoth isn't that big and at best has some club weapon.

Considering Liberty Prime is marked as a scripted completely unkillable creature (can't even do damage to it), its no wonder why.

i dont know. So long as the behemoth got close enough he could maybe like....throw liberty prime?

Edit: Oh my god, theirs no way the behemoth can throw liberty prime! I just watched the video gator country posted

Not even close. Behemoths are about 10 to 12 feet tall or so but Liberty Prime is as tall as office buildings.

Yeah I just saw the video theirs no way the behemoth can throw him. And he gets destroyed like instantly.

We do not know that lore wise.

Bethesda's mess of a game called "Fallout 3" is not consistent with other games or even in itself.

so are you saying the behemoth is actually stronger or are you saying that liberty prime is not with the lore? Btw your name and profile pic is awesome

I can't speak for him, but I'd assume he's referring to the innumerable plot holes and poor excuse for writing. Think about it, Optimus Prime and Super mutants the size of houses. I think someone explained the behemoths to me at some point, but the way I see it is both are questionable in and of itself.

Anyways I'd assume Optimus Prime would destroy a behemoth without much fight. In addition to "firin' mah lazer" he's got nuke grenades and sensors. Dear god I can't believe I even considered this, I've got to ask.. Is there a single person who thought Liberty Prime was actually a GOOD plot development or idea? Or is everyone of my mindset that it was a horrible, lazy mistake that should be expunged from the face of the earth?

I like liberty prime and even though some could say, "it could have been done better" or they just don't want prime at all I thought he was pretty awesome and i'm glad they added him.
