Era, Eon, and Epoch are Chlorm scientists. They implanted devices into Buzz and Warp Darkmatter during their academy days to study the residents of the galaxy. After Warp first began working for Zurg, at Epoch's suggestion, their study shifted to the differences between good and evil and which was better. (Eon preferred the former and Era the latter.) After learning of the implants, Buzz and Warp broke into their lab and prematurely ended their study. They were subsequently demoted (though Epoch maintains it was a lateral career move) to zoo and research facilities. They began kidnapping Galactic Alliance senators off Capital Planet for the zoo (as they see the other races as lesser, wild animals), but Team Lightyear thwarted them.
