REX-2000

REX-2000 is the sub-boss of the first Doppler Stage in Mega Man X3, a T-Rex like Ride Armor piloted by a soldier known as "Mad Joey" (マッド・ジョーイ) in its Rockman Factory toy. It will fire shots and small homing missiles at X while Zero tries to stop the descending of the spiked ceiling.

If Zero is not alive, a ceiling switch at the end of the room will impose a "time limit" for X unless it is destroyed. The switch's weak point is Triad Thunder.

Mad Joeys themselves appear as normal enemies in Rockman X DiVE, wielding a variety of weapons, just like Guardroids.
