The Nintendo GameCube adaption of Sonic Adventure 2, called Sonic Adventure 2 Battle, was released on December 10, 2001 in Japan, February 12, 2002 in North America, and on the GameCube's launch (May 3, 2002) in Europe, making it the first in the series to be released for the Nintendo system. This game changed a large portion of raising Chao. A Chao's stats can be viewed from within the game. The player can transfer one Chao from Sonic Adventure 2 Battle to the "Tiny Chao Garden" section in Sonic Advance, Sonic Advance 2, and Sonic Pinball Party with the GameCube-Game Boy Advance Link Cable. If a Game Boy Advance is connected without a GBA game inserted, a version of the Tiny Chao Garden can be copied temporarily into the Game Boy Advance's memory. Chao Karate was also introduced in this version. The Chao's stats are used against a computer-controlled opponent to fight in a fighting game style, but with minimal influence from the player and very little in terms of actual karate. The layouts of all three Chao Gardens were also changed slightly, with Sonic Adventure 2 Battle's Chao Gardens significantly smaller than those of the original Dreamcast version.
The "Battle" multiplayer options were expanded in the GameCube version, including the addition of new characteristics to the multiplayer-exclusive characters, while removing all online play. Also, the additional features for the kart mode are not required to be unlocked in the GameCube version.
There are several aesthetic changes, as well. In the GameCube version, minor special effects were added such as rain in the "White Jungle" level. Also, when playing as Knuckles or Rouge, an exclamation will appear above his or her head when directly nearby their targets. Some cutscenes were also redone slightly, with different character animations and camera angles. Some rankings had their requirements changed.
