The human piloted nanobot has three forms in Nanobots. It can change its form by entering a mutators, and while in its different form it has a slightly different appearance and uses a different weapon. Every form (except its weaponless Form) is coloured the same colour as a team, and wields a weapon that can damage enemies part of that team. The human piloted nanobot cannot stay as one form for the entire level or game, as its weapon it uses only damages one type (two if weapon stealer are counted), while the other two enemies are immune to it, forcing players to switch between forms.
