Everyone's favorite blue hedgehog is celebrating his 25th birthday on the 23rd of June. While I'm not a huge gamer, I fondly remember watching various Sonic-related shows during my childhood, and I still enjoy revisiting them occasionally.

Here are Sonic's best appearances outside video games.

1. 'Sonic Boom,' 2014-Present

Sonic Boom is the most recent Sonic The Hedgehog series to air, made to coincide with the spin-off series of video games of the same title. It is also the first Sonic show made entirely in CGI and marks the first update of the characters' designs in quite a while.

This series chronicles the efforts of Sonic and his friends to protect Bygone Island from the constant threat of Doctor Eggman's crazy inventions.

2. 'Sonic The Hedgehog: The Movie,' 1999

In this film, Sonic, Tails, and Knuckles must defeat Sonic's evil robot clone, Hyper Metal Sonic, before it destroys the peaceful Land Of The Sky.

Originally released in Japan as a two-part anime OVA in 1996, the two parts were edited into a single, 54-minute feature for Western audiences and re-titled Sonic The Hedgehog: The Movie. The Western release was delayed until 1999 in order to coincide with the first Sonic Adventure game.

3. 'Sonic Underground,' 1999

Sonic, Manic, and Sonia, royal triplets separated at birth, reunite to search for their Mother, Queen Aleena, and overthrow the evil Doctor Robotnik.

Sonic Underground was a completely unique take on the franchise, unlike any other Sonic series. Despite only running one season, it has reached near cult status among fans. A special one-shot continuation was a released as part of Archie Comics ongoing Sonic series. A comic book conclusion to Sonic Underground has long been rumored, but none has materialized.

4. 'Sonic The Hedgehog' or 'Sonic SatAM,' 1993-1994

One of the most well-loved Sonic series, Sonic SatAM featured Sonic and a team of Freedom Fighters work to free Planet Mobius from Doctor Robotnik's clutches.

In its early days, Archie's Sonic The Hedgehog comic books were inspired by this series.

5. 'Sonic X,' 2003-2004

In Sonic X, the second Sonic The Hedgehog anime adaptation, the core Sonic cast are transported to the human world. Sonic and his friends befriend Chris Thorndyke, a lonely human boy.

The first two seasons loosely adapted the two Sonic Adventure games, while Season 3 featured a completely original plot involving the evil Metarex. The title of the series' American theme song, Gotta Go Fast, remained a catchphrase of the entire Sonic franchise for years afterwards.

Happy birthday, Sonic!
