I am obsessed with Zyu 2 footage. Zyu 2 is a fan-term for the footage that Toei made for Saban for Power Rangers Season 1 and 2. Fellow Power Force Member John Green (grnrngr) has gotten hold of some footage from an anonymous source of Bloom of Doom and Invenusable Flytrap which has Megazord footage. He will be putting them as clips on his site like everything else for Zyu2. So this is to come in 2014.
