Notes

• "Neutronian" was first used as a species descriptor by the 2008 Breakaway toy bio, which was not noted by this wiki until 13 years later. It is unclear if the location name "Neutronia" being introduced in 2013's The Covenant of Primus is a coincidence or based on a shared internal source from Hasbro.
