We Meet Again, Sonic is a platformer game for the Wii, Wii U, Nintendo DS and Playstation 2. This game is only made to play in 2D and has the same plot for each system.


Although it features Adventure Time characters for the first time in the Sonic the Hedgehog series, the game is played in Sonic's world. The game lets you play as Sonic or Marsha, an Adventure Time character and a main hero, each taking their own routes of each level.

Every Marsha level, you use new attacks like Flash Step or Super Flight. Every Sonic level, you use classic moves like Spin Attack and spin dash.

Some bosses are from the Adventure Time World (fought by Marsha) while bosses from the Sonic the Hedgehog World (fought by Sonic)

Sonic and Marsha aren'tthe only ones to play. Although none of Marsha's friends join in, Tails and Knuckles do as well.


The story begins with Marsha in the grasslands. After completing Act 1, a sudden booms shocks Marsha as a dark cloud enters the sky and the screen flashes white.

It cuts to Sonic, Tails, Knuckles and Amy where they are facing the same problem. A black form passes them with screams of terror comming from inside it. In the distance, Marsha is yelling things like "Hey!" and "Get back here...uh...thing!" She blurs right past the four and Sonic gets up and runs after the brown blur. Tails follows behind as he flies after Sonic. Knuckles and Amy begin to follow after Sonic and Marsha.

After a while of running, Marsha begins to slow down and just falls on her stomach in exhaustion. Sonic stops when she does. Tails then determines that the black creature is a chaos monster, a beast that will destory the world and create chaos while doing it. Sonic and Marsha race through the world, restoring to peace and rescuing Marsha's friends. At one point, they notice at one point that the beast's weakness point is Chaos Emeralds.

After restoring the world and collecting the chaos emeralds, which they assumed is the creature's weakness, they discover that the mastermind behind the chaos monster is Dark Princess, who was a fake victim all along. Although the Chaos Monster manages to nearly defeats them, the support of Sonic's friends and the power of the Chaos Emeralds allow them to transform into Super Sonic and Super Marsha confront Dark Princess. Despite attacking with missiles and warping arms, the main heroes of the entire game destroys the Chaos Monster's core, destroying it. The heroes return to the present and celebrate. After the party, Marsha is seen arguing with Finn, about how he no longer actually respects her. Marsha finally makes up her mind and states that she was staying with Sonic and his friends. So, when Finn and all her old friends and her family all go through the portal to Ooo, Marsha stays behind and is seen crossing her arms, showing no emotions for her old home.
