¡Hola chicos, mi nombre es Pron!
—Pron. He's just.. Spanish. Duh.
Pron is a happy-go-lucky Carbot who lives up in Madrid, Spain, he is best friends with Jazz and Tobot W in Cybertron, but his enemy is Swindle, the member of the Combaticons.
He was also Ace's 2nd-in-command until Storm (Ace's brother) and Meister showed up, leaving him in 4th-in-command. Pron didn't mind as he thought they were more worthy.
He's also very good friends with Born, both of whom utterly despises Swindle, because him and Bumblebee are better Yellow transformers than him.
He once first saw the Cementygas as he almost drove on it in his car mode by Bob the Builder, until he turned into his Police car form, as Bob saw him in his Police car mode, he ran away to the Tubby Tower
He transforms into a sports car; specifically a 2014 Hyundai Avante. Pron has guns hidden in his doors; he deploys them when infiltrating and paralyzing Decepticons.
