Powers & Abilities
Being part-Galvan, Dark Matter possesses enhanced intelligence similar to Grey Matter, allowing him to instantly recharge Ben's Omnitrix by inputting a specific code sequence. Due to Albedo's mutation experiment, however, Dark Matter is more powerful than Masaru and most likely smarter than him.

Dark Matter has enhanced strength.

Dark Matter can shoot dark red fireballs from his hands that encase enemies in a red crystal-like substance.

Dark Matter can secrete a dark red cerebrospinal fluid, which he can harden into a plaque and manipulate it to form weapons resembling the red crystal produced from his fireballs.

The weapons Dark Matter creates from out of his body are a by-product of his mind. While the energies generated in a regular Galvan lead to the acceleration of synaptic activity, in Dark Matter, those energies-undirected or improperly directed-create the dark matter he issues out from inside.

Dark Matter's cerebrospinal fluid can be utilized as a fuel for automobiles.
