The only fanfic series of the franchise following its own continuity.
Ever since Cybertron’s creation, the Divine Spark, the power source of the Universe and the main core of Cybertron, has protected the Transformers from any evil that threatened their existence. However, a group named the Decepticons, led by Megatron have made their mission to use the Divine Spark’s power to conquer the universe. The Autobots have sworn to protect the Spark from Megatron’s clutches and have fought their enemies for years. However, the Divine Spark one day escapes to another planet called Earth. Both of the groups fled their home to retrieve the Spark before it and the universe self-destructs. Little do they know that the Spark is now the power source of not only the Universe, but is now transformed an autistic teenage girl named Aura into a powerful entity.
Now the Autobots and their new friend, Aura, try to fight the Decepticons, protect the universe and learn more about themselves than they realise.
This is the dark, serious, sci-fi, hilarious, dramatic and most importantly, character-based fanfic series; Transformers: Warriors United!
Ice drove them apart, aeons separated them, and now they're divided by war. Even though it's been nine million years, though, Starscream and Skyfire are still fighting for that elusive second chance, fighting to keep what's left of their bond... unbroken.
