Jacknab

Jacknab is a Corvicon and the brother of Boostwing and Pilfer in Transformers: Robots in Disguise.

History
Jacknab arrived in Crown City with his brothers and hatched a plan to steal all the gold from the Crown City Gold Depository. He and Pilfer threw off the Bee Team's trail by making it appear Boostwing traveled at impossible speeds. After Boostwing got taken into custody, Strongarm pondered over the fact that he could be in multiple places at the same time and realized that he'd had to have partners and that the Crown City Gold Depository would be where they would find "the brightest shinies on the planet". She found Jacknab there stealing tons of gold, and she tried to catch him, only for the third brother, Pilfer to show up. The two brothers overwhelmed Strongarm and subdued her. Jacknab prepared to harvest her optics as trophies to give to Boostwing, but when the rest of the Bee Team arrived to foil his plans. Strongarm knocked both of them out with a net of heavy gold. Defeated shortly thereafter, Jacknab found himself cuffed to Pilfer and advised he had the right to run in silent mode.
