The backbone of the Dire Wraith invasion forces, the Wraith Soldiers are the muscle of the Wraith army. Despite this, their skills are not viewed in high regard by the order of the Space Knights and they're not told too much by their commanders.
While on a training cruise with new cadets, Rom and Livia found a mining colony infested with Wraiths. To Livia's annoyance, there were exclusively from the Soldier caste and she viewed the assignment as beneath her time despite Rom insisting that it taking little time meant it was worthwhile to see it through. These Soldiers proved crafty however with one managing to lure the hot-blooded Cadet Auxin into an ambush for his Neutralizer. They'd overlooked the nearby car however which soon revealed itself to be Stardrive who mopped up the Soldiers in a rather one-sided battle. The next morning, at Vekktral's command, a Soldier attempted to assimilate Sky Blast which resulted in an out of control Wraith/Cybertronian hybrid. Once the fighting spilled over onto Xetaxxis, the Wraiths replenished their forces by assimilating the natives and turning them into Soldiers. The Soldiers posed as Xetaxxians and played on Bumblebee's sympathies to lure him, Sata and Ultra Magnus into a trap. Though they nearly succeeded in assimilating Bumblebee, they proved little match for Ultra Magnus who ordered his allies to depart while he held the Soldiers off. The sheer number of them however proved too much for him and after dispatching a hundred of them, they managed to pin down the Autobot allowing Vekktral to possess him.
In 2016, Rom turned his Neutralizer into its lance configuration and tossed it at a Wraith to slay it. Believing him to now be an easy target, a Wraith Soldier lunged at Rom who extended his blade and engaged the Soldier in melee. Emerging victorious, Rom began torturing it for information and it revealed that alien cloaking technology was behind the recent failures of his Analyzer. The Soldier was saved from further torture when Darby Mason made Rom see what he was doing and Camilla Byers confirmed to Rom that the Soldier had told all it knew. At Camilla's urging, Rom then quickly executed it.
After arriving on Earth, Orphion tracked a large amount of Wraith Soldiers to an oil platform. Prior damage to his armor had rendered his Neutralizer offline but he was still too fast for the surface crew who fled. By the time they'd marshalled their courage and broken out their weapons, Orphion's own were back online and he slew them all crushing the last with his tail. After Rom took a stand against his commander, Orphion sent Livia down below to use the platform to destroy Earth only for a second squad of Wraith Soldiers to make themselves known and attack her. Despite their numerical advantage, she managed to defeat them.
In 2017, Rom attempted to save a human from being turned into a Wraith soldier but failed. The newly assimilated soldier and two others stood guard for two Wraith Sorcerers discussing the effects of their magical virus before they were attacked by the Micronauts who dispatched the Wraith Soldiers with ease, Larissa offering her apologies to the one who had once been human. After the virus had been stabilized, other humans were turned into Soldiers only for Rom to quickly put an end to their suffering.
