Meet Brain Freeze. Confirmed to be the offspring of Megatron, Brain Freeze joined his cause, in hopes of succeeding him. But Starscream often gets in her way, which irritates her as much as her ‘dad’ does.
 
Soon, Megatron became Galvatron, and Galvatron soon died at the hands of Toastertron. Now Brain Freeze is just another of Toastertron’s pawns under orders to steal the magical geodes from the Rainbooms, so that Toastertron would take over Canterlot.
