Phantom Cell is a Bydo life form that can mimic other lifeforms, including massive and very complex creatures. Its native form is an enormous purple cell-like creature.
In the battle it turns into several forms:
- 1. Phantom Cell
- 2. Dobkeratops Albino
- 3. Laios (Airborne Assault)
- 4. Darth Gomander
- 5. Gun Dutchman
- 6. Phantom Cell (shooting)
In the first stage it simply slowly follows the R-90 around and does not actually take damage, though points are still scored for hitting it: it will always transform into Dobkeratops as the boss theme's intro concludes regardless of how much damage it takes.
- The theme song of the Phantom Cell is a remix of the original R-Type Boss theme, fitting since this battle is a Boss Rush of past R-Type bosses.
