Blurr from Transformers Robots in Disguise is a young, enthusiastic, and incredibly fast Autobot who originally came from the planet Velocitron. Before arriving on Earth, he was an up-and-coming celebrity racer, considered among the fastest of the fast on his home world, where serving in his pit crew was once regarded as a great honor. He is known for his sleek blue and white racing car vehicle mode and a tendency to speak as quickly as he moves.

In terms of personality, Blurr is eager and well-meaning but often impatient and prone to prioritizing speed over precision. He has a strong desire to help others, yet his approach can be reckless, as he tends to opt for getting a job done fast rather than getting it done right, sometimes unwittingly endangering those around him. This behavior stems from a background where he was a celebrated star, and his time on Earth has become a learning curve where he discovers he is not as perfect or as well-liked as he once believed. While not a bad individual at his core, he has shown moments of self-preservation, such as trying to run from danger or lying to avoid repercussions for his actions. He mainly wants to live without obligations, responsibilities, or speed limits, though he is open to guidance.

His primary motivation in the series involves finding his place within a team environment. After the restoration of Cybertron, he was blacklisted by the High Council for being a supporter of Optimus Prime, which likely contributes to his desire to prove himself. He is driven by a need for validation and a genuine, if sometimes clumsy, desire to be a hero.

In the story, Blurr first encounters the Bee Team when he intercepts a plane's distress call and saves Sideswipe from a fall. This introduction leads to him accompanying the team back to their base. His arrival immediately creates tension with Sideswipe, who fears that the faster, younger newcomer is trying to replace him on the team. Throughout the episode, Blurr works alongside Sideswipe to recapture a dangerous Sharkticon named Ragebyte. Contrary to Sideswipe's fears, the mission concludes not with Blurr taking his spot, but with Blurr becoming Sideswipe's intern.

Blurr's key relationships are primarily defined by his dynamic with Sideswipe. While initially a source of insecurity for Sideswipe, they ultimately develop a working partnership where Blurr reassures his teammate that he is trying to help, not usurp his position. He is also starstruck upon meeting the rest of the Bee Team, including Bumblebee and Grimlock, showing a sense of awe toward established heroes. His background as a Rescue Bot also defines his previous life, where he worked alongside characters like Salvage and Heatwave.

Throughout his appearance, Blurr undergoes subtle development. He starts as a self-absorbed celebrity racer who lies about his heroics to gain approval. However, after being given a second chance by Optimus Prime and working with the Bee Team, he begins to learn the value of teamwork and responsibility. His arc moves from seeking personal glory to accepting a supporting role, such as becoming an intern, indicating a growing humility and understanding that being a hero requires more than just speed.

Notably, Blurr has been alive for well over ten thousand years, having been in a stasis pod on Earth for a significant portion of that time before being revived. His most notable ability is his incredible speed, which allows him to outpace almost any opponent. This speed extends to his thought processes and speech patterns, making his dialogue notoriously difficult for other characters to follow. He is also a capable fighter, though he often relies on his velocity rather than brute strength.
