Tails isn't as fast as Sonic but he can fly. Tails was created in 1992 by Naoto Oshima and his first game was Sonic the Hedgehog 2 in the same year for Game Gear, Mega Drive/Genesis and Master System (all by SEGA). Tails is also Sonic's best friend since the Sonic Classic Era (1991-1998) and today. He also has his own games. Tails' English voice is played by Kate Higgins.
Tails is 8 years old in the video games (18 in real life) and in the Game Gear version of Sonic the Hedgehog 2, Sonic needed to rescue Tails by collecting 6 chaos emeralds and Sonic's other friends becuase since Sonic went on holiday to another island in Mobius (as in various European or American sources) but when he went back, all of his friends were gone. This was Dr. Eggman's fault, who put Sonic's friends in his face shaped cofins that Sonic destroys at the end of each stage. In the Mega Drive version of Sonic the Hedgehog 2, Tails is Sonic's sidekick.
In Sonic the Hedgehog 3 and Sonic Spinball (both 1994), Sonic jumps off Tails' aeroplane (a plane known as the “Tornado”). Tails is the cleverest character in Team Sonic and he has invented vehicles/machines such as: Sea Fox (in Tails Adventure, 1995), the Tornado (which Sonic helped build, first appeared in 1994) and sea vehicles used in Sonic Rush Adventure (Nintendo DS, 2007).
