Bumblebee is a fictional robot character appearing in the many continuities in the Transformers franchise. The character is a member of the Autobots, a group of sentient, self-configuring, modular extraterrestrial robotic lifeforms.

In the original line of toys and in the animated series, Bumblebee is a small yellow Volkswagen Beetle. In the live action movies, he has appeared as vehicles inspired by the Chevrolet American muscle cars – with the live-action film versions being a yellow Camaro with black racing stripes. The original vehicle-mode design was based on a classic European Type 1 Volkswagen Beetle. The character is named after the bumblebee, a black-and-yellow striped insect which inspired his paint scheme. Bumblebee is a fan-favorite character and he appears in most of the series and later becomes the main protagonist in Transformers: Robots in Disguise, Bumblebee, and Transformers: Cyberverse. Bumblebee has also taken the form of a Willys Jeep in the 2018 film, Bumblebee. Bumblebee is the little brother of the heroic Autobots and a mascot, constantly striving to prove himself in the eyes of the other robots—especially his leader, Optimus Prime. This often causes him to take risks and put himself in danger. He is portrayed as a smart aleck, a capable, reliable messenger and spy, and his small size allows him to go places that his larger commanders cannot. He is highly fuel-efficient, has great visual acuity, is particularly adaptable to undersea environments, and transforms into a Saturn yellow Volkswagen Beetle. He was later reconstructed into a stronger, more mature form as Goldbug.
