Tiranos

Tiranos (ティラノス) is the triceratops-like enemy (despite the name sounding like Tyrannosaurus) in Mega Man X2. Tiranos was originally an exihibition from a robot museum, but was modified into a tank-like Mechaniloid for ground warfare. They mainly appear in Wheel Gator's stage, but they also appear in the third X-Hunter Stage and as an enemy summoned in battle by the Sigma Virus.

Tiranos also appeared alongside the Sigma Virus in Dragon Poker.

A Tiranos is seen alongside other Mavericks ready for Zero. More are later seen with Disk Boy 08s and Tubamail-Ss attacking the city on Wheel Gator's orders, and they destroy X's Ride Armor.
