Burn Dinorex

"Zero... you've come here to retire me, even when the Earth is about to come to an end..."

- Mattrex

Mattrex, known as Burn Dinorex (バーン・ディノレックス) in Japan, is a Reploid from Mega Man X5 based on a Tyrannosaurus. Mattrex was a member of Repliforce's disaster prevention team, and is among the survivors of the Repliforce incident in Mega Man X4. Mattrex was stationed in the Sunhouse Mountain, and without the Repliforce's knowledge, had created an illegal warehouse to hide weapons he had created using magma energy. In Mega Man X5, the Hunters discover Mattrex has the rocket Booster Engine necessary for the Shuttle, but as he didn't trust the Maverick Hunters, he thought they wanted to retire him and attacked them, leaving X and Zero no other choice but to destroy him as a Maverick. It's unknown if he had succumbed to the Sigma Virus.

He sends out flames from his Ground Fire either setting the floor on fire or creating small clusters of flame, and also can perform a eruption flame while using a dash attack. Air is his weakness, so use The Skiver's weapon, Wing Spiral (with X) or W-Shredder (with Zero) to bring him down quickly.

Trivia

 * In the American version, Mattrex was named after Matt Sorum, the former drummer of the rock band Guns 'N Roses.
 * Mattrex's mugshot in the beta had him facing left where as in the final, he's facing straight forward as the other mavericks (with the exception of Duff Mcwhalen).
