Burn Dinorex

Burn Dinorex (バーン・ディノレックス Bān Dinorekkusu), also known as Mattrex[2], is a Reploid from Mega Man X5 based on a Tyrannosaurus. Burn Dinorex was a member of Repliforce's disaster prevention team and is among the survivors of the Repliforce incident in Mega Man X4.

Burn Dinorex was stationed in a volcano in the northeast of Africa. Without Repliforce's knowledge, he had created an illegal warehouse to hide weapons he had created using magma energy. In Mega Man X5, the Maverick Hunters discovered that Burn Dinorex had a rocket Booster Engine necessary for the Space Shuttle. But, as he didn't trust the Hunters, he assumed that they had come to retire him for his activities and attacked, leaving X or Zero no other choice but to destroy him as a Maverick. It's unknown if he had succumbed to the Sigma Virus.
