An Alpha Sandigger is the alpha specimen of a Sandigger pack, with larger jaws and longer body length. It shares most of the physical characteristics, weaknesses, and abilities that its smaller counterparts can use, and does not seem to possess any unique abilities or qualities beyond its size.
One resided in Aether's Agon Temple, and Samus Aran battled it when attempting to reach the energy controller. The battle was not a lengthy one, though, as an Ing with Samus' Morph Ball Bombs ability possessed it seconds into the fight, transforming the Alpha Sandigger into the more-powerful Bomb Guardian. Both the Sandigger and the Ing possessing it were killed by Samus, returning to her the use of her Morph Ball Bombs.
The Alpha Sandigger is one of the simplest and easiest bosses in the game; the creature doesn't last long, and the fight serves as the setup to the Bomb Guardian. Samus must shoot either of the eyes until the Alpha Sandigger gets possessed by an Ing, turning it into the Bomb Guardian and increasing the difficulty.
- The Alpha Sandigger, like the Alpha Splinter, gets possessed by the Ing. Unlike the Alpha Splinter, however, which is programmed to take a certain amount of damage before the Ing arrives to possess it, the Alpha Sandigger is set on a timer; the Ing will eventually arrive, regardless of the Sandigger's health.
