"Cheer Power" is the fifteenth chapter of the Story Mode in Mario & Sonic at the Olympic Games Tokyo 2020.

Plot

After learning how the Excitement Battery works, Luigi and Tails go to other venues to charge it via the crowd. The first place they go to is the nearby Tokyo Stadium, where they find Diddy Kong, who asks if they are there to watch. After Tails corrects him that they are playing, Diddy Kong reveals that he is as well, so Wario steps up to face him in Rugby Sevens as he claims that it is his time to get a gold medal. Wario and his team of blue Boom Booms manage to outplay Diddy Kong and his red Boom Booms. Thanks to the crowd cheers, the Excitement Battery charges a little more. Diddy Kong suggests that the heroes go to the Musashino Forest Sport Plaza nearby. There, they find Knuckles and Shadow, both of whom know the gist of the whole situation that is going on. To help them charge the battery, Shadow and Knuckles take to the Badminton court together to please the crowd in a Doubles match. Peach and Yoshi team up as the two that will take them on. After they manage to win against Shadow and Knuckles, the battery charges even more. Knuckles is upset at his loss while Shadow claims he would have won if it was just him. Knuckles decides to join Luigi and Tails' crew to help them while Shadow also joins them and advises them to stay focused to the end. Knuckles then remembers that Jet, another one of Sonic's rivals, was searching for Sonic at the Olympic Stadium. Tails decides to go there to tell him what happened while Shadow tells them to be careful of him as he seemed to be worked up. After traveling back to the Olympic Stadium, the gang realizes that Jet is nowhere to be seen. Suddenly, Jet pops out of nowhere and orders the group to stay away from the field because of the Football match that is about to happen. Jet then wonders where Sonic is because he promised a penalty kick shootout with him. Luigi explains the whole story, which Jet does not believe, and Tails states that they need to charge the battery. Knuckles then decides to take Sonic's place in the shootout and face Jet instead in order to excite the crowd. Knuckles wins against Jet, who blames only luck for his loss. The battery fills up even more, but Tails realizes he and the other heroes are out of entry passes again and wonders what they will do.
