How Alex joined the Tourney
Both Roger and Alex are the result of a military experiment. Dr. Bosconovitch wanted to combine the genes from a martial artist and cross it with a wild animal. It is rumored that Doctor Strange has stolen Roger and Alex and is keeping them with him and the other Illuminati. 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.
