The Autobots take the AllSpark back to their ship, but are soon confronted by a crew of Decepticons led by the notorious warlord Megatron and consisting of Blitzwing, Lugnut, Blackarachnia, and Starscream.

The Autobots go into stasis to survive the crash, while the scattered remains of Megatron are discovered by a human scientist named Isaac Sumdac.

Optimus Prime and the Autobots awaken from stasis and defend the people of Detroit from a monster, resulting in them becoming local celebrities.

They befriend Professor Sumdac's young daughter Sari, who teaches them about Earth customs, and whose security card is transformed into a metallic tool which possesses a fraction of the AllSpark's vast cosmic power.

Blitzwing and Lugnut arrive on Earth searching for Megatron, while Blackarachnia targets Optimus Prime, blaming him for her techno-organic mutation.

New Transformers introduced in the first season include the Autobot Arcee (who only appears in Ratchet's flashbacks), the Decepticon Soundwave, the bounty-hunter Lockdown, and the Dinobots Grimlock, Snarl, and Swoop.

Several human villains are also introduced, including Nanosec (who can run at extreme speeds), the Headmaster (who pilots a machine that attaches to and controls large robots) and Meltdown (who is covered in a toxic and corrosive substance).

The Autobot Elite Guard members Ultra Magnus, Sentinel Prime, and Jazz arrive on Earth to retrieve the AllSpark, only to learn of its destruction in the Season One finale.

New characters introduced in season 2 include the Autobots Omega Supreme (who was revealed to be Optimus Prime's team's spaceship), Wreck-Gar, Wasp and Blurr, the Decepticons Shockwave, Swindle, Mixmaster and Scrapper, the human villain Slo-Mo (who is able to slow down time using a watch embedded with an AllSpark fragment), and Starscream's army of clones Thundercracker, Ramjet, Skywarp, Sunstorm, and Slipstream (none of the clones are openly referred to by name in the series, the names listed come from the toy-line, while Slipstream was retroactively given her name by Hasbro).

The revelation that she's a robot sends Sari into a whirlwind of shock and disbelief, immediately suspecting her "father" as her creator, despite Sumdac's insistence that he discovered her in a liquid metal form.

Using her Key's energy, Sari evolves into a formidable armored techno-organic teenager with advanced weaponry and unique Cybertronian abilities.

Optimus defeats Megatron with the aid of Ultra Magnus' Magnus Hammer (which destroys Megatron's fusion cannon) and a "Wingblade" jetpack built by Professor Sumdac, Ratchet, and Sari while Prowl sacrifices his own vital Spark to reassemble most of the AllSpark into what resembles the Matrix of Leadership, killing Starscream in the process, and destroying the "Lugnut Supremes" all at once.
