Sonic Adventure 2 Battle is the only game to offer another way for Chao to compete against each other, called Karate. Like races, you can access karate from the Chao Stadium.
As you can probably tell from the name, karate involves two Chao going head to head in battle. Your Chao needs to be strong to win the four emblems on offer!
How to Win
Each battle has a 90 second time limit, and is fought in a ring. There are three ways to win:
- Deplete the opponent's health bar.
- Knock the opponent out of the ring.
- Have more health than your opponent when the time runs out.
Obviously, you will lose if the opposite things happen to you. If you happen to run out of time and have the exact same health as your opponent, then the game will be a tie!
As with Chao Races, the majority of the battle is simply up to your Chao. However, you can cheer your Chao on. There is a bar at the bottom of the screen for each Chao, called the Zeal bar. It represents your Chao's energy or motivation.
The Zeal bar will gradually deplete over the course of the match. It will increase slightly when your Chao lands a hit on the opponent, but will decrease if it misses or gets hit itself. If the bar empties entirely, your Chao will stop fighting and will begin meditating; this makes it an easy target for your opponent! You should rapidly tap the A button to cheer on your Chao and increase its Zeal.
Each of the stats has a different function:
|Swim||"Defence" — Increases your Chao's defence, lowering the damage that your Chao takes from enemy attacks.|
|Fly||"Stealth" — Increases your Chao's evasion, making it more likely to dodge enemy attacks.|
|Run||"Speed" — Increases your Chao's attack speed, meaning it spends more time attacking and less time doing nothing. This is a very useful stat, as a constant flurry of blows prevents your opponent Chao from being able to attack!|
|Power||"Power" — Increases your Chao's attack power, meaning that your Chao damages the enemy more with each hit, and sends it flying back further. This helps you to win by knocking your opponent out of the ring, as well as depleting its health! Your Chao will also learn new attacks as its Power increases, such as a spinning kick or twisting punch!|
|Stamina||"Health" — Increases your Chao's Zeal bar, keeping it more motivated during the battle.|
The Interleague Game is a multiplayer match between a Chao from Memory Card A, and a Chao from Memory Card B. Have one of your friends bring their Memory Card over so you can battle your Chao! You can't win any emblems, but you will gain glory if you win.
The Tournament is the main mode of Chao Karate. At first, there are three difficulty levels available: Beginner, Standard, and Expert. You can enter your Chao in any of those levels, but it is recommended that you start with Beginner.
Each difficulty has five opponents, and you must beat each opponent in order before you can complete that difficulty level. Once you clear a difficulty, you will earn an emblem! If you manage to clear all three difficulty levels, you will unlock the Super difficulty, which also has an emblem as its prize. This means that there are a total of four emblems to earn from Chao Karate.
Your Chao will also earn a rank based on its performance in Chao Karate. You can view its rank at the Health Center.
