Power Bomb Guardian

The Power Bomb Guardian is a Sporb possessed by the Ing which stole Samus's Power Bombs, which Samus can retrieve by defeating it.

Logbook Entry

 * Power Bomb Guardian: This darkling Sporb has absorbed the ability to generate Power Bombs. It can fire these dangerous weapons instead of the venomous needles it normally shoots. The energies of the Power Bomb weapon have made it all but invulnerable. Tremendous kinetic damage will override the protective field, however.

Battle
The last of the Sub-Guardian bosses, Samus fights the Power Bomb Guardian in Dark Torvus. Instead of needles, it shoots Power Bombs, and it is impervious to Samus's weapons. However, it can be killed by dropping the ceiling on it. To do this, Samus must ride Spider Ball tracks around the room and laying Morph Ball Bombs in the four Bomb Slots holding the ceiling up. The Power Bomb Guardian is considered by many players to be the easiest boss in the game (short of the Dark Missile Trooper), as the Spider ball tracks are easy to navigate and the power bombs aren't particularly damaging. There are light crystals on the ground so you can heal but run between them or you will be a sitting duck for it's power bombs and the Inglets on the ground.

Trivia

 * Power Bomb Guardian is the only Sub-Guardian that was a possessed plant.
 * If a player has the Gravity Boost upgrade, Dark Suit, Dark Visor, and enough energy tanks, they can retrieve Samus's Power Bombs from a lake in the Dark Agon Wastes without having to fight this boss. This is not recommanded unless the player knows the quickest method to reach the expansion and to get out of the lake before Samus dies.
