how big, 'bout the size of a semi. I think :tftongue

i'd say 9 meters

I'd say he's about 18 to 20 feet tall. I have a schematic poster of Prime on my wall, and that's about the dimensions on it. Also, the Master Piece/20th Anni. Prime is, more or less, to scale with the alternators (all 2 of them to be released around here so far!) and at that scale I'd say he was about 20 feet tall. Interesting poll!

probably 12...

from the Master Peice Convoy Booklet;

 

How tall would you say Convoy is? The specs of giant robots and mechs appearing in Japanese robot anime are almost always established in detail, but in the case of TRANSFORMERS, nothing so strict was set up. In the character chart used when the first series was being produced, he was depicted as being about 6 m tall, which is about the height of a two-story residential home in Japan. In the TV cartoon, this was generally depicted as the norm, and from comparisons with Spike and others, it seems he was regarded as being about 6 m

THough I don't like math I say at least 3 storys tall, whatever the actually feet are.

Well, lets look at one of those flat nosed semi's. They're usually 18 feet long right? well, since primes legs extended and the front goes down, that's maybe an extra 10 feet and the head would roughly be around 5 feet. Wait, can't forget the smock stacks, 1 extra foot. so he must be around 34 feet. Hey, i'm just pulling this outta my ass.

Those semi trucks are much longer than 18 feet. I have a old Mark III Lincoln that longer than 18 feet. If I was going to by the choices given, I would say he would be around the 12 meters / 39 feet size. But the other choices are getting more like the size of the combiners. Oh yeah and M.E.G.A.S. is 80 feet tall :thumb
