The FinalHedo's name comes from Godzilla: Final Wars's title, specifically the word final (ファイナル?, Fainaru), and Hedo, which comes from Hedorah's Japanese name, Hedora (ヘドラ?).
The suit is mostly gray with reddish pipes scattered around its body. It has red eyes with bright yellow irises, with eyes slanted inwards. The main body has a much less trashy look than the first suit, and it is thinner than the ShodaiHedo suit, with more distinguishable legs. The spines on the tail are much more pronounced.
