There is something hilarious about the Transformers/Evangelion mash-up. Even beyond the ludicrous colours which results from the Unit-01 Prime. Somehow the very idea of colliding Transformers with the dark cynicism of the human condition and the somewhat twisted freudian metaphors of Evangelion has very much the feel of being a "banana and marmite sandwhich" kind if idea.
I wish that Eva Prime had a larger (and cheaper) run, because I wanted him badly. I also would have killed for and Eva Unit-02 decoed Grimlock, Shockwave decoed as Unit-00, a Sachiel decoed Starscream, and Soundwave decoed as Israfel.
