A trio of Neutrino mercenaries were known for invading the minds of other organisms to steal information for whoever hires them, leaving the victim's body in a vegetative state. The Neutrinos were hired by Vrax Belebome to obtain information from Michelangelo's mind. With the help of the inner Michelangelo and the figments of the characters within Michelangelo, the Neutrinos were defeated.
The Neutrinos are large, red, and bulky aliens with one red eye on their head.
- Neutrinos are small in the real world, but large in someone's mind like the Dream Beavers.
- The 2012 Neutrinos resemble the Mindless Ones, mystic extra-dimensional beings and enemies of the Marvel Comics character, Dr. Strange.
