Alex is a cloned
Dromaeosaurid made from a fossil by Doctor Bosconovitch
Mishima's tenure as the head of the Mishima Zaibatsu. He
was a "palette swap" for Roger
in Tekken 2 and TEKKEN Tag Tournament, sharing Roger's moveset in animations. Alex returned in TEKKEN Tag Tournament 2 with his own character slot and his own unique moveset. Alex is intelligent for his kind, and, while he is never shown to be able to speak like
Kuma II can, he shows some humanlike characteristics and seems to be able to understand the English language.
