Bumblebee Bird agreed with Grimlock Bird that the argument was an entertaining one. Their truce was a shaky one, however, with Optimus Prime Bird and Megatron Pig soon arguing with one another on the battlefield. The two factions joined forces against the newly arisen threat. The squabble was interrupted when the Flock's eggs, which had previously been exposed to the EggSpark, sprouted mechanical limbs, multiplied, and proved themselves to be excessively hostile. The rest of the Autobirds then joined in the fight, finding themselves evenly-matched against their opponents. The clobbering he received damaged Bumblebee Bird's vocal processor, forcing him to communicate in beeps and squeaks from that point on. This once more proved to be foolish, as he was beaten down by Lockdown Pig, and trampled by Megatron Pig. He was unable to stop himself from charging the pigs by himself.

When the Autobirds caught up to the Deceptihogs, Bumblebee Bird's former brash persona once more came to the forefront. His old mannerisms nonetheless still shine through when the situation becomes heated, proving that he's the same old Chuck despite his personality overhaul. which honestly weirds out his teammates, who are unused to seeing him acting this way, especially Red. He displays a much more level-headed and responsible attitude.

When upgraded by the EggSpark, Chuck assumes the identity of Bumblebee Bird, Rodimus Bird, Cliffjumper Bird, and Cosmos Bird In this new form. To compensate, Chuck displays uncanny speed and sheer destructive potential, making him an asset to the Flock despite his personality flaws. Unfortunately, Chuck's need to make up for his past screw-ups sends him hurling headlong into trouble, repeating the cycle all over again. Gung-ho, impatient, and overconfident, Chuck has often been the cause of Red's plans falling apart, despite his heart being in the right place. Chuck is the kind of bird who jumps into the fray first, and worries about the consequences later.
