Press Disposer (プレス・ディスポーザー Puresu Disupōzā) is the boss the player faces in the first Doppler Stage of Mega Man X3 if both Bit and Byte were destroyed. It resembles an elephant that hangs onto the top-right part of the screen. A conveyor belt scrolls enemy robots onto the screen, and then destroys them when they reach the right side of the screen.

The Press Disposer will grab X with a claw, dealing a lot of damage. It will use several other attacks with its "trunk", but when it is destroyed, damaging acid will fill the bottom part of the screen. The head above the trunk must be aimed instead. The Press Disposer is weak against the Ray Splasher or Tornado Fang.
