Sonic Boom is a cartoon comedy series that is aimed at children centering on Sonic, with his friends, Tails, Amy and Knuckles, their never ending search for adventure and their battles with their nemesis Doctor Eggman. Other characters, both new and old, will also join the ensemble.
Sonic lets martial arts action movie star Tommy Thunder follow him around and observe his "hero process". However things get bad when Tommy's over-the-top ego clashes with Sonic's and starts claiming credit for the team's battles.
After Tails' Ultrasonic Speed Amplifier device makes Sonic go so fast that he disappears and is trapped in another plane of existence, the team must think of a way to get him back.
Sonic lets Mark the Tapir, a fanatical, self-proclaimed “number-one fan,” become his personal assistant, but Mark eventually goes too far.
Believing himself too good to be trapped, Sonic challenges Tails to come up with a way to catch him.
When Eggman concocts a plan where Sonic will have to fight him underwater, the hedgehog must overcome his hydrophobia in order to stop him.
