On top of a sky liner, Team Rose meets Team Sonic just as they escape the Power Plant. While Sonic is both surprised and nervous to find Amy there, Amy is determined to force Sonic to marry her, while Cream and Big wish to ask him where Chocola and Froggy are, respectively. Having no choice, Sonic and his team are forced to battle.
Wandering through the jungle, Team Rose and Team Chaotix come across each other. Vector tries to ask Amy a question politely, but Amy assumes he wants to date her and tells him to wait as she leaves with her team. Vector becomes flustered by this and calls her a brat. Espio then demands that they hand over Cheese to them as he assumes Cheese to be one of the Chao they were ordered to protect earlier. This makes Cream believe that they are the ones that took Chocola which angers Big. As a result, both teams start to fight.
The object of these battles is to knock Team Rose off the edges of the battle platforms into the bottomless pits surrounding them. There is no damage system in this boss, meaning Team Rose cannot be defeated by simply damaging them. Grabbing the Power Cores and Rings before the opponents is crucial. Without Rings, Team Rose will fly back farther, making them easier to be knocked off. Some characters are more suited to battle Team Rose's member due to having moves that are most effective against their particular formations:
If the player loses any team members, they can be brought back to the field by performing the Team Blast.

In this arena, there are a total of nine Power Cores; three blue, three yellow, and three red. Start by grabbing the Blue Power Core in the center (so Amy cannot use it), then when the other team members are near, have Sonic use Blue Tornado to fling them into the air. While they are grounded, you can collect more Power Cores or steal their Rings. Also be sure to look around, because there is nothing more annoying than to get hit from behind. This is a fairly easy battle, and you should be able to get an A Ranking after a couple of tries.
In this area, there are only three available Power Cores and they sit outside the arena in balloons. There is also a Shield hidden in a wooden Container on the stage. For this battle, Team Rose will be much more difficult to defeat as they will always switch to the formation that is dominant over the player's.
Start the battle by switching to Fly Formation and knocking Amy’s team out of the air with Thunder Shoot. This will knock them down temporarily. Switch to Vector and start using Power Attacks on them to knock them out of the ring. Once all three members are knocked over the edge, the battle is over.
