Tails is Sonic’s best friend, practically an adopted brother to him. He’s always tinkering with new gadgets and inventing new things. His namesake twin tails help him fly when he rotates them like a helicopter. During the Optimus and Megatron’s war, he accidentally used their Allspark on a new jet of his and made Scattershot, the first Mobian-born Autobot. He then made four more, thus forming the Technobots, and raised them as his sons. During the Year of Unicron, he held onto Cosmo’s regeneration seed and cared for it until it bloomed into Cosmo’s new Mobian body. Nowadays, he’s the C.E.O of the tech company, Miles Electric, and is a doctor of technology. He’s married to Cosmo and lives with her in the Botanical Sector of Station Square on Mobius’ continent of Northern Imperia. His genius will be needed against the Author and his ilk.
