Some TMNT stuff really isn't for little kids.

Neutrinos are a race of extra-dimensional humanoid aliens from Dimension X. These characters were originally designed for the 1987 TV series and first appeared in the episode "Hot Rodding Teenagers from Dimension X". They're easily identified by their pointy ears and zany hairstyles.

In the IDW continuity, the Neutrinos are once again an alien race in Dimension X revolting against General Krang and his Stone Soldiers. This continuity's version of Professor Honeycutt is a Neutrino who sacrificed his mortal body to escape to Earth in order to find help against Krang.
