Hi-Test (RID)

Hi-Test is among Soundwave's group of Mini-Con subordinates.

Season 3
In Guilty as Charged, Hi-Test surreptitiously observed Strongarm and Nightra patrolling a forest road. He attempted to steal Strongarm's Decepticon Hunter only to disturb some birds, prompting Nightra to run and Strongarm to follow. Hi-Test later opened a GroundBridge portal to report back to Soundwave, who berated him for his failure. Frightened, Hi-Test fled, with Soundwave threatening to offline Hi-Test.

In Collateral Damage, Hi-Test took to following Bumblebee's team for a while afterwards. He finally revealed himself after knocking Laserbeak away during an fight with Optimus Prime before linking himself up with Optimus to upgrade him. With the additional power provided, Optimus successfully defeated Laserbeak and destroyed Soundwave's beacon generator. After explaining himself through Optimus, he was encouraged to make the Shadowzone his home as no one would hunt him there, disappearing through another Groundbridge portal.

Trivia

 * The script for the episode "Railroad Rage" called for Hi-Test to appear and steal Strongarm's Decepticon Hunter, even though he had left Soundwave's team of Mini-Cons three episodes earlier. Fortunately, the error was noticed before the episode went out, and Hi-Test was subbed out for new character Goldgear. As a result, the two share a body-type.
