In the Archie comics, Sonic's real name is revealed to be Olgilvie Maurice Hedgehog. He tries desperately to protect that information, possibly out of embarrassment. This name is not canon (official) in the game continuity, however, and he is simply known as Sonic the Hedgehog in the games.
Miles "Tails" Prower is an 8-year-old fox cub and the sidekick of Sonic the Hedgehog and a character of the series. Ever since his first appearance in Sonic the Hedgehog 2 for the Sega Genesis, people considered him as cute, and is the best friend for life of Sonic the Hedgehog as well.
It's fairly common practice in animation for women to voice young male characters like Tails. Over the years, O'Shaughnessey has learned how to modulate her voice for different characters as part of honing her craft.Apr 9, 2022
When not using his twin tails to move through the air, Tails can also use his two tails to give him a speed boost when moving along the ground, by using them to propel himself forward at breakneck speeds. This allows Tails to reach speeds nearing those of Sonic himself.
Tails was always male and 10 years old.
Sonic's pals are also inspired by animals - Knuckles is an echidna, and Tails is a fox. Echidnas live in Australia and New Guinea; and are also one of only three mammals that can lay eggs! In some Japanese folktales the number of tails a fox has indicates how old and powerful it is.
The film follows Sonic and Tails, who join forces to find the Master Emerald before Doctor Robotnik and Knuckles the Echidna can.
