Well, here's my notion of the coolest movie ever, if I can just get the respective companies to see the potential in teaming up the greatest heroic characters in Japanese cinema and television for an epic, all out battle with their respective greatest foes. These are the iconic Kaiju and Henshin that I loved watching on TV as a kid and like a LOT of other people always wished that some fantastic peril would befall the Earth requiring all these classic characters to join forces to overcome it. My line up and potential advesaries are-
Godzilla (Gojira) / King Ghidorah
Gamera (friend of children) / Gyaos
Ultraman / Baltan
Giant Robot / Nucleon
Gigantor (Tetsujin 28) / Black Ox
Voltron / Dracatron
King Kong (Kingu Kongu) / Mecha-King Kong
Optimus Prime / Megatron
Brave Raideen / ? any suggestions

I enjoy hearing what you guys think about this silly ass stuff I draw, so if you're inclined, please leave comments, its fun reading em!
