Kaiju (Big in Japan)
From Tardis Wiki, the free Doctor Who reference
A green kaiju had merchandising in the form of shirts and action figures. A yellow-shirted child played as this character against another child playing as a mecha in an open test of the Consec 5000. Unbeknownst to the testers, due to the game console's incorporation of a Kaznak Simu-System, their player characters were projected into the real world, where their battle caused destruction and chaos.
