At the start of Sonic Generations, Tails and Sonic's friends throw a surprise birthday party for Sonic. Sonic is given a chili dog as a present from Tails, but when the Time Eater appears, it gets blown away (much to his disappointment). Later on, the party continues when the Time Eater is defeated and Sonic gets back his chili dog, which is still warm. Silver, Shadow and Classic Sonic joined the party following the battle.

AoSTH birthday

Sonic's party in AoSTH.

In the Adventures of Sonic the Hedgehog television series, Sonic has a birthday in this series.

In the episode "Tails Prevails", as a gift, Tails built Sonic a flying bike. Realizing Tails' potential with mechanics, Sonic asked Professor Von Schlemmer to make Tails his research assistant. However, Dr. Robotnik captured and impersonated Schlemmer to get Tails to build his latest anti-Sonic weapon.

In the episode "Robotnikland", Sonic has another birthday, with Tails gathering some of Sonic's friends for a party.

Archie Comics

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Freedom Fighters throw a birthday party for Sonic on his first birthday after his return from space. During the party, Bark and Bean attacked the Freedom Fighters, but were easily handled by the group with the help of Shadow the Hedgehog. It turned out that Dr. Eggman sent Bark and Bean to attack the Freedom Fighters, and upon finding out his plan failed, sent Croctobot to attack Sonic.

Once it arrived, Sonic laughed at the robot and called it pathetic. As the Freedom Fighters battled the robot, Rouge and Scourge arrived on scene. Before Scourge could attack Sonic, they both, along with Shadow, are grabbed by the Croctobot. The three hedgehogs destroyed the robot together. With the robot dealt with, Scourge attacked Sonic and then Shadow when he interrupted him. The other Freedom Fighters joined Sonic's side, causing Rouge and Scourge to flee. With the attacks over, the group finally celebrated Sonic's birthday.
