Ejoornian

The Ejoornians are a species originally from the planet Ejoornus before relocating to the Eshems Nebula.

Biology
Despite their appearance, the Ejoornians have a biology near-identical to that of a Cybertronian, with some features being practically copied and pasted into their internal structure. Some researchers even suggest they have a spark core, yet they appear to be incapable of transformation.

History
The Ejoornians used to live on Ejoornus until they were driven off-world by the Quintessons, who had colonized and renamed the planet New Quintessa. The defeated Ejoornians then relocated to the Eshems Nebula where they would dwell for years.

Detecting a powerful energy source coming from a planet located light years away, they launched several scout vessels. only to have a minor skirmish with Starscream, who was scouting nearby space himself. Eventually, the Ejoornians launched a full-scale assault on a peaceful Cybertron to claim the source of the signal but were repulsed by the Cybertronians.

In the invasion's aftermath, Prowl and Jazz of the Security Force checked up on the AllSpark, which was stationed at a temple in Simfur under guard by sentries Bumblebee and Cliffjumper. Prowl examined the attack pattern, which indicated that the Ejoornians were trying to breach the temple rather than destroy it. Jazz took Prowl's analysis as evidence that the Ejoornians were after the AllSpark.

Meanwhile, Ratchet and Arcee examined an Ejoornian body that had been recovered in the post-battle cleanup at a laboratory in Burthov and found that the aliens' biology was eerily similar to the Cybertronians'. But before more study could be done, Signal Flare arrived under orders from Optimus to assemble for a meeting immediately.

At the gathering, Optimus explained how a suddenly emboldened Megatron was rallying his troops in a brutal counterattack against the Ejoornians. Megatron's army swiftly wiped out the entire Ejormian fleet at the expense of betraying Cybertron's principals of pacifism. Megatron later remarked to his new master Megatronus Prime that if any Ejoornians survived, they would speak of Cybertron's power.
