The Chao Attack (チャオアタック,Chaoatakku?), also called the Cheese Attack, is the signature move of Cream the Rabbit and Cheese, and the duo's primary form of offense. When performing this technique, the user orders Cheese to attack enemies from afar.
Sonic Advance series
Sonic Advance 2
Making its first appearance in Sonic Advance 2, Cream is the only character to use the Chao Attack. When performing it, Cream points forward, commanding Cheese to quickly turn around and back, charging towards the enemy at moderate speed and destroy/damage the enemy.
To perform Chao Attack in gameplay, the player must press . This can be done either on the ground or while in mid-air. This attack can easily defeat the bosses of this game.
Sonic Advance 3
In Sonic Advance 3, the Chao Attack is performed like in Sonic Advance 2. In addition, Cream's Tag Action transforms Cheese into a Chao version of her partner and allows them to use the Chao Attack for a limited time as well.
A similar move called the Chao Ball Attack can be performed by Cream and Cheese when partnered with Sonic the Hedgehog, where Cheese is launched forward in a blue aura instead of homing onto nearby enemies. When Cream is in Boost Mode (she must be partnered with Sonic to enable this), Cream can perform this attack without interrupting her speed, allowing her to remain at Boost Mode. While partnered with Amy though, Cream can only perform Chao Attack while in mid-air.
In Sonic Heroes, the Chao Attack is called the Cheese Attack. In this game, it serves as the Fly Formation and the Solo Attack for Team Rose. When using the Cheese Attack, Cream sends Cheese into enemies and destroys them on contact (unlike other Solo Attacks for the Fly Formation which only stuns enemies), though this attack is the slowest of them all. It is very useful during Battles and boss battles with other teams, capable of knocking the opposing team off the platform.
To use the Cheese Attack in gameplay, the player has to press // when Cream is without her teammates.
The Step Attack (ステップアタック,Suteppuatakku?) is basically the Chao Attack performed at high speeds. It is a move used only by Cream the Rabbit and Cheese. It has so far only appeared in Sonic Advance 2.
In order to perform the Step Attack, Cream must perform the Chao Attack while in Boost Mode. The resulting speed from the Boost Mode will then transform the Chao Attack into the Step Attack.
When using the Step Attack, Cream will take a long stride forward, while Cheese circles around her as a shield at high speeds and as a result, it will destroy or damage any enemies Cheese makes contact with. Most importantly though, the Step Attack allows Cream to maintain the speed she is running at and remain in Boost Mode, unlike the normal Chao Attack which would make her slow down.
In other media
In the Sonic X anime, Cream and Cheese, though rarely participating in any fighting, have used the Chao Attack. It first appeared when Emerl went on a rampage and appeared unstoppable due to his ability to copy others' moves. By using multi-attacks with Cheese however, the Chao Attack included, Cream was able to defeat Emerl since he could not copy two skills at once.
Cream and Cheese have also developed a Spin Attack variant of the Chao Attack. When using this attack, Cream throws Cheese as he dashes towards enemies in ball form.
In Sonic Advance 2, the Chao Attack can be used to collect Special Rings.
Cheese is able to attack armored and spiky foes with little effort and has never been injured by attempting this attack.
