okay, getting a post up tonight 4sore

also, upon finally finding some character models, I can safely estimate Omega's height to be possibly 800+ft.

This is all going on the guess that Optimus is at his usual 30 foot-ish height

[quote=Wikipedia on Metroplex height]According to the one Japanese Comic Bom Bom article Metroplex is 800 meters tall. In the Marvel U.K. Transformers comic however it says he's 698 feet (212.8 meters) tall. He can lift 70,000 tons.[/quote]

large sizes are not unprecedented. If you look at the size scale for Omega and Trypicon, you can see Omega is 1/2 the size Trypti is. With Metroplex aprox the same size as Trypticon, it could make sense that Omega is at 800+ ft.
