Energy Analyzer

Never leave home without the Analyzer. A wrist mounted Space Knight gadget, it allows the user to scan any lifeform to see if they are what they appear to be or if they're just a Dire Wraith imitation.

It does not work on Cybertronians and is essentially a hi-tech version of Buster's nose.

Fiction

2005 IDW continuity

While on a training cruise at Mining Colony 25-6-41, Rom instructed that Analyzers should be used in concert with intuition to sniff out Dire Wraiths. He did not need to use it as the Wraiths simply jumped at him. After the Knights had mopped up the Wraiths, Rom scanned the area with his Analyzer with the results coming up clear meaning that the Knights did not need to shatter the entire planetoid.

When a Galactic Council delegation arrived at Orchid Crossing, the Knights scanned the shuttle with their Analyzers, with no Wraiths being detected. When Vekktral revealed himself however and the Wraiths began killing, Astrotrain assumed his robot mode and Livia realized he'd shielded the Wraiths from the Analyzers. Shining Armor #1

After arriving on Earth in 2016, Rom's Analyzer began to fail him. He soon learned this was due to the Dire Wraiths harvesting samples of Ore-13, information he shared with the Autobots upon allying with them. O Ship of State After the Micronauts and Snake Eyes had joined them, his Analyzers picked up an army of Wraiths approaching Autobot City allowing the group a few precious seconds to mount a final defense. The New Colossus

After that mess had been sorted, Rom's Analyzer led him to Verenya where he found several humans mutated with Wraith genetics as a result of the Talisman. His Analyzer revealed that they were not true Wraiths, however, so he informed G.I. Joe to use non-lethal countermeasures. While following the sounds of battle to try and find the Talisman, Rom displayed the Analyzer's nifty flashlight function.

After the Oktober Guard had been felled, Rom tried to use the Analyzer to gleam the true nature of the Talisman to no avail. Once the guard had teleported it (and Action Man) away, he tried to use the Analyzer to track the teleport signal but failed to detected it anywhere on Earth even after hours of trying. It did however pick up the signal of true Dire Wraiths, which forced him to take his leave. Crisis Intervention
