Invincibility — Ben 10 Protector of Earth PS2 & PSP

Code: XLR8 → Heatblast → Wildvine → Four Arms

The code makes Ben and his alien transformations immune to enemy attacks and fire. However, invincibility does not prevent death from falling off cliffs or from very high places.

The code gives Ben and his alien transformations a green and transparent appearance.

The code unlocks all combos for the five aliens available in the game.

Unlock Alien Forms — Ben 10 Protector of Earth PS2 & PSP

Code: Wildvine → Four Arms → Heatblast → Wildvine

If they have not already been unlocked through normal gameplay, this code immediately unlocks the five aliens available in the game.

Although the game is called Ben 10, Ben 10: Protector of Earth has only five playable aliens.

Master Control — Ben 10 Protector of Earth PS2 & PSP

Code: Cannonbolt → Heatblast → Wildvine → Four Arms

When attacking enemies while transformed into an alien, the Omnitrix will not lose its energy.

The code changes the colors of Ben and his alien transformations to grayscale, giving the characters a darker appearance.
