Knockout

KnockOut is a medical officer and former member of the Decepticons. Originally, KnockOut was relocated to Earth after being summoned by Starscream to aid the damaged Megatron. KnockOut soon made a rival in the Autobot scout Bumblebee. When Breakdown was killed by Airachnid, KnockOut took a less active role for the Decepticons, in part due to his reliance on the former and resorted to using various weapons to get his point across during battle. KnockOut no longer served as an antagonist in the series, after he joined the Autobots in Predacons Rising.

Once the Autobots defeated Megatron and took over the Nemesis, KnockOut claimed joining the group as they were restoring Cybertron. He was knocked out by Miko in the Apex Armor and taken as a prisoner to the planet. There, KnockOut helped the Autobots while they were under siege by whacking Starscream with the Immobilizer from behind, destroying the device in the process, proving that he really wanted to join them. The team welcomed KnockOut into their side and he remained with them ever since. KnockOut also became a part of their family.
