Airing in Japan on 12 August is a late-night special for Transformers Prime. This special is set to air between 2:45 and 4:45 am Japanese time, and is hosted by the voice actors of Miko, Sierra and Vehicon in the Japanese dub. The content includes a recap of the episodes so far, comments from the cast, a newly filmed Tokyo Joshi-ryu Transformers Club segment (the girl band who appears in a weekly segment airing with the Japanese dub of the show) and a comparison of Japanese and American Prime episode #12 (Predatory) focusing on the director, Yoshikazu Iwanami's take on Airachnid's character.
The show is also supposed to cover past Transformers series. Check out the (Japanese) advert page here
