Tekken 2
Prologue Text: "Both Roger and Alex are the result of a military experiment. Doctor Boskonovitch wanted to combine the genes from a martial artist and cross it with a wild animal. It is rumored thatDoctor Abel has stolen Roger and Alex and is keeping them with him in his secret laboratory. Alex is a hybrid of a prehistoric dinosaur and a lizard, and he is also the result of splicing Roger's genes. There have been similar species on the Earth many years ago".

Ending Description: Alex is studying a rock that appears to have a dinosaur fossil in it. A dinosaur's face flashes on the screen and Alex roars and starts running, gradually gaining speed. He runs up the mountain and, having got to see one of his ancestors, happily jumps up into the air, putting one of his fists up.
