Were villains from an alternate dimension (excluding AbareKiller) created when the meteor that caused the extinction of the dinosaurs hit, and emerged from said meteor under the leadership of Wicked Life God Dezumozorlya, with some members (Lije, Jannu, and Gelidon) originally being from Dino Earth.
Consisted of various mutants and altered humans led by Mesogog, a monstrous entity who developed within Anton Mercer.
The Evolian forces remained unified under Dezumozorlya's leadership throughout the series, though AbareKiller later led the group temporarily while Dezumozorlya was dormant before he was discovered to possess Dezumozorlya's other half. The Barmia Soldiers were their sole force of foot soldiers,
Mesogog's Army employed Tyrannodrones as their original foot soldiers, but later gained the Triptoids as well. Zeltrax later split from Mesogog's forces, taking the Triptoids with him.
Dezumozorlya sought to unite its divided essence from the two parallel worlds and assimilate all life in existence, and employed its minions in this task.
Mesogog's army sought to return Earth to the state in which it existed at the time of the dinosaurs so that reptiles might again rule the planet, and those loyal to Mesogog continued to pursue this mission after Zeltrax's departure.
AbareKiller (Mikoto Nakadai) joined this group of his own free will and remained until his connection to Dezumozorlya's other half was discovered, to which he then turned against them.
White Dino Ranger (Trent Fernandez-Mercer) was brainwashed into joining the group. After he was freed, a clone of him was created for the group before being destroyed by the original.
Jannu was reverted back to Mahoro mid-way through the season, before rejoining the group, but this time as an undercover spy for the Abarangers before being captured until the finale when she was freed.
Elsa did not reform until the finale, to which she was later captured before being freed.
