No respectable interstellar power goes out into the hell that this is the galaxy without a signature weapon. For the Solstar Order, that weapon is the Neutralizer. A highly versatile hand held weapon, it unleashes a beam of devastating red energy that (usually) has lethal results for whatever was unfortunate enough to be in its path.
Rom's first experience with a Neutralizer came when the Dire Wraiths invaded Elonia where he grabbed Diavod's discarded weapon and fired at the Wraith that had once been his mother. While she escaped, Rom impressed the Knights with how he handled the weapon and was invited to join their ranks. Nikomi explained that the weapon had multiple settings, the higher the setting, the longer it would take to recharge. By the time Rom had graduated, the Mark III Neutralizer had been released but Rom's group still used older models much to his ire.
When attacked by Dire Wraiths, the obsolete Neutralizer failed to work before it was absorbed by a mysterious alien ore and enhanced.
When the Wraith/Solstar War moved into the larger galaxy, it was deemed unacceptable that a Neutralizer fall into Wraith hands with any collateral damage taken to prevent this being deemed acceptable. The Neutralizers could be detached from a Knight's armor and transformed into a javelin like weapon.
Neutralizers came in a variety of forms with several Space Knights chose to integrate multiple Neutralizers into their armor. Dire Wraith homeworld.Combining multiple Neutralizers produced increasingly devastating effects with the effect being used to shatter the
Two large scale models were built for Stardrive though, owing to her Camien heritage, these ones were integrated directly into her biology. Several Wraith Soldiers attempted to kill Cadet Auxin for the chance to study his Neutralizer only for Stardrive to defeat them. When the Decepticons broke onto Orchid Crossing, Neutralizers proved only marginally effective against them forcing Livia to use her light cannons to slay Ursa Major. When the Autobots arrived, Rom fired his weapon at Ultra Magnus which did little damage and invited a powerful retaliatory strike. After Sky Blast had been infected by a Dire Wraith, Neutralizers had no effect on the resulting Wraith/Cybertronian hybrid. On the surface of Xetaxxis, Rom unleashed the full power of his Neutralizer upon Ultra Magnus downing him, but only for a second. Livia and Rom then combined their Neutralizers but Magnus resisted the onslaught. When Livia fought Starscream, the Seeker was surprised that the weapon actually hurt. Attempting to bargain with Starscream, Stardrive bluffed that she would use her Neutralizer to destroy the energon synthesizer.
When Stardrive attempted to defect from the Space Knights, Livia used her Neutralizer to shoot down the cadet's jet mode. Stardrive simply turned to car mode and rammed Livia head-on while dodging another Neutralizer barrage. Sata came to her commander's defence but her Neutralizers simply annoyed the Camien. After cooler heads began to prevail and the Decepticon/Wraith alliance closed in for the kill, Rom used his to disintegrate several Wraiths trying to swarm them.
Upon arriving on Earth in 2016, Rom used the full power and spread of his Neutralizer to completely raze Cooper's Mill to the ground with enough precision to spare Darby Mason's house though doing so had left his weapon drained. At its lowest setting, his Neutralizer would have the precision to remove Camilla Byers's Wraithmark, but the process stood a chance of killing her anyways.
Though the Neutralizer could function as a sniper-rifle, the false Joe Colton and four false other G.I. Joes. During at heated debate in Autobot City, Rom fired the full power of his weapon directly at Optimus Prime who, despite being blown back the kinetic force of the attack, was undamaged.it had a limited range in this regard and would need to revert to large spread firing mode to kill its targets. Rom used his weapon to slay
When forced into combat with Orphion, Rom absorbed his commander's Neutralizer from right out his armor. The physical weapon was merely a conduit however as Neutralizer energy could be channeled directly through the armor. Orphion sent his Neutralizer energy down the Wraith drill shaft in an attempt to destroy Earth. Though he succeeded in slaying the Wraith Sorcerers below, the majority of his energy was absorbed by the Presence. The three Space Knights combined all three of their Neutralizers to destroy the Wraith Priest.
After Livia's energy had been drained by the Presence, Rom used his Neutralizer energy to resuscitate her but left them both drained of energy. Using what little Neutralizer energy they had, they jury rigged two boats into bombs before fashioning Neutralizer spears to combat Scylla's army.
Rom's Neutralizer recharged in time to destroy Scylla's extra heads with Livia's recharging in time for the two to slay the Wraith general.
Later on, Rom was approached by the Micronauts regarding a Dire Wraith plot but they read as Wraiths to his Analyzer prompting him to attack. The Micronauts' small size allowed them to dodge the Neutralizer before Acroyear sliced it in two. Though in pain from the weapon's destruction, Rom fired Neutralizer energy from his eyes at the Micronauts before Biotron convinced him to stand down. Afterwards, Rom reabsorbed his weapon and used it to burn the Wraith-taint off his allies. Catching up with the Dire Wraiths at a carnival, Rom used his weapon to slay D'rge's acolyte before destroying the Wraith virus.
- The early Neutralizers seen in ROM Annual 2017 are based off the original Rom toy's Neutralizer.
- In ROM #8, Orphion refers to his bow shaped Neutralizer as a Neutra-Bow. Whether other configurations have other special names is unknown at this time.
