As far as tallest is concerned, Beast Machines Supreme Cheetor for me as well. Bulk and height combined would probably go to Supreme Devastator.

 

Brave Maximus, by a long shot.

 

hmmm.....for me biggest is definately Brave and Fort Max.

second, depends on if we are talking transformers only, or transforming toys.....if transforming toys that goes to Great Ganbaruger. He's only a few inches shorter than max, and then God Raijin-oh.

If just Transformers, yeah, would be Unicron and Company.

 

you could have an oversised KO fortress maximus.....
Mine would be supreme starscream, unicron, God ginrai and G1 scorpinock.

 

I am pretty sure a KO doesn't even exist...at least that is what the general concensus is...

 

Not an oversized one anyway. An undersized KO of good quality is confirmed to exist. For me, a tie between Cybertron Optimus Prime and Cybertron Megatron.

 

Brave Max for sure.
