Ultra Bleu follows Jim Park for the first 24 hours after a violent break up with his ex-boyfriend and how a chance meeting with a stranger reveals deeper issues he must confront.

This season began merely two whole weeks after the first season had ended, on April 19, 2008, with the airing of The Elite Guard, and ended on July 5, 2008, with the two-parter, A Bridge Too Close. The season revolved mainly around the Autobots in the aftermath of Megatron's return, trying to restore the city and their image. Meanwhile, Megatron, Lugnut, and Blitzwing have captured Prof. Sumdac in order to build a Space Bridge, hoping to use it to conquer a weakened Cybertron from within. A sub-plot also focuses on Sari as she searches for her father, while learning that there is no record of her existence of any means. Also, Blackarachnia (originally Elita One) has been reduced to a minor recurring character, only appearing in one episode of the entire season (Black Friday).

Jimmy Park is visiting home for the first time in years and has nothing to show for his time living overseas in Seoul. But old tensions come to a head when he confronts his homophobic sister at a family dinner.
