The series focuses on Bumblebee who, following the events of Prime, has become a police officer on Cybertron. While on a mission, he sees a vision of Optimus Prime telling him to go to Earth as a terrible evil is coming. Joining him on the mission are his cadet partner Strongarm and the rebellious Sideswipe. Following their arrival on Earth, the three of them are tasked with capturing Decepticons who were released from their stasis pods when their prison ship, the Alchemor, crash landed. The trio is also aided by the humans Russell and Denny Clay, the Dinobot Grimlock, and the Minicon Fixit. Later, they are joined by the former Decepticon-turned-Autobot bounty hunter Drift, with his Minicon pupils Slipstream and Jetstorm, and the spiritual Windblade who is on a mission by the Transformers' god Primus. The first season, consisting of 26 episodes, concluded with the revival of Optimus.
A second season, consisting of 13 episodes began airing on February 20, 2016, and saw Bumblebee's team, or Bee Team, attempting to apprehend the remaining escaped Decepticons and the discovery that the Alchemor was cut in half upon crashing on Earth, leading to the creation of a different Decepticon group. The season also features the return of Soundwave and Ratchet from Transformers: Prime—the former appearing for one episode while the latter appears in the two-part finale.[4][5] A miniseries, consisting of six episodes, premiered in October 2016 and features the return of Starscream, placing him as the main antagonist.[6] In April 2017, the series' third season, entitled Combiner Force, began airing and focuses on Bee Team's realization that they can combine into the Combiner, Ultra Bee, as well as the arrival of the Stunticons, who are also capable of combining. Soundwave also plans to return with the help of Activators, a new breed of Minicons.[7][8]
The series concluded with its third season and was replaced with the new series, Transformers: Cyberverse.[9] Presently, only the first season of the series has been released as a complete DVD set, in 3 Regions, which are Region 1, Region 2 and Region 4.
While helping Strongarm to apprehend Sideswipe, Bumblebee gets a vision of Optimus Prime that draws him back to Earth with Strongarm and Sideswipe along for the ride. He finds that the Decepticon prison ship Alchemor has crash-landed on Earth and its Decepticon inmates have escaped. After using a Space Bridge to arrive on Earth, the three discover a lone Chompazoid called Underbite. They eventually engage in a brawl with him, but they unwittingly endanger two humans, Denny Clay and his son Russell.

Bumblebee's group works to bring in a group of Skunkticon Thieves led by Malodor. Meanwhile, in the Realm of the Primes, Optimus Prime prepares himself for an evil that will threaten both Earth and Cybertron while being trained by the first Minicon, Micronus Prime.
Bumblebee's group encounter the crab-like Decepticon Clampdown, who inadvertently leads them to Steeljaw, who has Underbite, Thunderhoof, and Fracture on his side. A battle ensues in one of Crown City's landfills, in which Bumblebee faces a near-death experience.
Denny and the Autobots are captured by a murderous, vampire Deception called Nightstrike in the cave system outside Crown City who brings their worst fears to life with his sonic scream. Now, a panic-stricken Russell has to race against time to rescue them.
After Sideswipe is abducted by an insane scientist called Vertebreak, in the Crown City subway, Vertebreak performs a surgery to graft his head into Sideswipe's body. As the other members of Bumblebee's team must find Vertebreak in order to get Sideswipe's head back onto his body, the young Autobot must learn that he can’t always rely on his physical prowess.
Drift returns to Earth in pursuit of a disgruntled, runaway Jetstorm, who left without reason. At the same time, Bumblebee's team faces Springload and Quillfire who have escaped from their stasis cells. Springload's madness for the search of Doradus leads Quillfire to steal a giant experimental tank form a military base, proving a difficult challenge for the team.
Unaware that Grimlock hides a serious injury, Bumblebee and the team make their way to the ocean in pursuit of an escaped aquatic Decepticon named Octopunch, who retreats to a Cybertronian spacecraft to activate its engines and leave Earth.
Former gladiator-turned-Decepticon Groundpounder escapes and takes part in a televised fight in the Rumbledome stadium and the Autobots have to depend on Grimlock and his brawn to help defeat him and his devious coach Headlock.
Fixit becomes increasingly buggy. Denny tries to repair him but it goes horribly wrong, wakes his guard program and converts Fixit into a fully weaponized and lethal prison guard who mistakes the Bee Team for Decepticon fugitives. Armed with an arsenal, he tries to attack the others. Meanwhile, Chop Shop's right arm component makes another attempt to free the rest of Chop Shop and succeeds in causing more troubles for Bumblebee's group.
Steeljaw and his group manage to get into the scrapyard to release their fellow Decepticon prisoners that the Autobots have captured up to now and establish a sonic field around the scrapyard which the Autobots cannot penetrate. Our heroes will have to show cunning to thwart the Decepticons' plan and regain control of the scrapyard.
Grimlock discovers another Dinobot fugitive named Scowl with whom he sympathizes. A restless Grimlock ponders returning to his old habits and decides to help Scowl flee but it does not take long for Scowl to start causing destruction and terrorizing the humans, having been hired by Thunderhoof on Cybertron. The heroes will have to join forces to stop Scowl. Meanwhile, Denny redecorates a motor home for Russell who is afraid that his father will build it his own way.
Sideswipe meets an ancient Autobot named Windblade on a mission for Primus after she has just defeated a Decepticon. She agrees to team up with Bumblebee's group to bring in a Decepticon named Zizza, who desires to spread her toxin through airports in order to hypnotize humans and take over the world.
When Bumblebee decides to show his team the beauty of Earth, he takes them to a ghost town called Edmond Ville in the Far West where the shape-shifting Decepticon Pseudo awaits them. As they wander through the town, Bumblebee's group gets into various hijinks and trigger multiple traps. Afterwards, Bumblebee finds his team fighting something that isn not really there and stops them. They are informed by Fixit that they are dealing with a Decepticon that is able to change his appearance. Despite Pseudo opening up various holes in the ground, in an attempt to trap Bumblebee's team, they manage to escape and defeat him.
Bumblebee's team finds themselves in trouble when Strongarm, Windblade and Sideswipe are captured by Steeljaw's pack. In the wake of a coming threat to Earth the Primes decide to send Optimus there despite his training not being yet complete. The Bee Team must prevent Steeljaw's pack from teleporting that same threat onto Earth.
Megatronus, the Fallen, has returned from exile and prepares to send both Earth and Cybertron into oblivion. Bumblebee's team, reunited with newly revived Optimus Prime must use everything they have learned to save both worlds from annihilation.
Optimus is weakened when Micronus suddenly strips him of the power of the Primes. Despite the rest of the Autobots' worry, Optimus insists that he can continue to be of service. A Decepticon shows up in the Arctic Circle, with Optimus, Drift, Windblade, and Sideswipe heading after him while Bumblebee, Strongarm, Fixit, and Grimlock stay behind and are soon ambushed by an ancient Decepticon named Overload, who holds a grudge against Optimus for defeating him several years ago. The Autobots thus have to cope with a global Decepticon threat and a weakened Optimus.
Bumblebee continues to chase after Overload with Grimlock and Strongarm not too far behind, while Optimus and his group continue to pursue Polarclaw and battle against the elements in the Arctic.
While the team tries to apprehend a new Decepticon named Saberhorn, Strongarm and Grimlock try to recreate the teamwork she and Sideswipe had. Meanwhile, Steeljaw, who survived the disaster with Megatronus, discovers another group of escaped prisoners led by two new Decepticons.
After making a mistake in the field, Strongarm removes herself from active duty just as the team contends with the Decepticon arsonists Crazybolt and Slicedice.
Windblade's concern for Optimus' well being puts the Away Team at risk as they battle Razorpaw and his Minicons, Swelter and Glacius, who have the ability to manipulate temperature.
Grimlock attempts to make himself smarter by absorbing information from a Cybertronian data cylinder into his processor, but something goes wrong and puts the team at a disadvantage as they battle the Decepticon scientist Simacore and his Minicons Axiom and Theorem.
