Chase is a supporting Autobot in the Transformers franchise. Part of Heatwave's Rescue Force Sigma-17 team, alongside Boulder and Blades, it's the team's duty to ensure the safety of Griffin Rock, alongside the Burns family. It's fitting that Chase chooses the alternate mode of a police cruiser, because they don't come more law-abiding and by-the-book than him.
Frank Cwiklik tries his hand at Chase for the Rescue Bots Academy series. Much like his fellow Sigma Rescue Bots, Frank's Chase appears to have mellowed in time, but not so much that he's lost his stoic and law-abiding attitude. Frank does a pretty good job of following in DC's footsteps (his vocal footsteps, that is).
I need to put the cuffs on DC Douglas, because he's stealing my vote.
