An Alpha Splinter is the alpha male of a Splinter pack, essentially a larger Splinter than its fellows. It uses the simple jumping attack deployed by all Splinters. However, the jumping attack of the Alpha Splinter is harder to evade than the jumping attack of smaller Splinters, since it jumps ahead of the direction of its target. Ironically, after being possessed by the Ing, this jumping attack became just as easy to avoid as that of normal Splinters.
A group of Splinters and an Alpha Splinter resided in Aether's Great Temple inside Splinter Cocoons (the alpha had a far larger cocoon). As Samus Aran walked into the center of the Temple Sanctuary, the Splinters and the alpha exited their nests and attacked. Samus managed to destroy them all, but not before the Alpha Splinter was turned into a Dark Alpha Splinter by an Ing. It would seem that the Ing were going to use the Splinters and Alpha Splinter to steal the last amount of planetary energy from the Energy Controller located in the vicinity.
Whether or not the Alpha Splinter and its smaller brethren were peacefully living with the resident Luminoth in the temple is unknown.

Morphology: Alpha Splinter
Alpha male of a war pack. Gigantic predator. Very swift and strong, it uses ramming attacks to defeat its foes.
Splinter war packs are dominated by the largest male. Alpha Splinters use their tremendous strength, size, and speed to subdue and kill prey, paving the way for their smaller broodlings.
Episode of AetherEdit
In the manga Episode of Aether, the Alpha Splinter was much larger than its in-game version, and differed morphologically from it in several ways, such as having teeth and a large central eye. It was also appeared in a different area near the crashed GF ship and was attempting to kill one of the surviving Galactic Federation Marines before Samus intervened. A few shots from her power beam were enough to beat it.
- If the player uses game hacking device to get Power Bombs during the Alpha Splinter fight, and uses them on it, it will completely disintegrate, effectively killing it before the scripted Ing possession. The Ing particles will then have nothing to possess, and fly harmlessly around after Samus, and then vanish, leaving Samus trapped, and without the Energy Transfer Module.
- Where all Splinters, Dark Splinters and the Dark Alpha Splinter follow Samus through the room, the Alpha Splinter will jump back to the center of the room after every leap.
