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.
