Sonic x Lilac in Transformers: Rise of the Beasts

After Sonic was captured and his friends attempted to save him, Dr Eggman sent him to a different universe along with the Chaos Emeralds. The same phenomenon happened with Sonic's girlfriend, Sash Lilac. In this new universe, on Earth, they meet the Autobots: Optimus Prime, Bumblebee, Arcee, Mirage and Wheeljack, and humans Noah Diaz and Elena Wallace. The Autobots locate a space object called the Transwarp Key to use it to get home, but half of it ends up in the hands of Scourge, a Terrorcon servant to a dark hungry god called Unicron who eats planets.

After they lose the key, they meet Airazor, a Maximal from another planet who lost her and her friends' home to Unicron. While searching for the other half of the key, they come face-to-face with the rest of the Maximals who have allied with humans and their leader, Optimus Primal. This journey will forever change Sonic and Lilac's lives.

Can the two anthropomorphic friends survive this adventure and make it back home, or will they meet defeat at the hands of Scourge and Unicron?

This story is a slight reimagining of Transformers Rise of the Beasts, originally written by Darnell Metayer, Josh Peters, Erich Hoeber, Jon Hoeber,
Joby Harold. My retelling has new characters: Sonic and Lilac.
