It is also capable of reproducing it´s nanobots into a an phenomenon called Grey goo, where self-replicating nanobots take over planets.

Abilites:

 * Speed: It is capable of travelling at high speeds and capable of hiding and retreating quickly.
 * Strength: It easily climbs walls with only it´s feet (or also arms) and overpowers strong monsters, though most of his strength in battle comes from manipulating the battle field.
