Sonic Adventure/Sonic/Prologue

It is nighttime in Station Square, with the city operating as usual. Everything seems to be running smoothly for Sonic the Hedgehog, until he sees the police taking some action to the City Hall. Sonic follows and the police surround some watery monster, Chaos. They shoot at him, but it does no harm and the police retreat. So Sonic takes action, and the Adventure begins. This is the first boss in the entire Adventure mode.

Chaos 0

 * Difficulty: Easy
 * Damage: 3 hits

Chaos 0 is a quick and easy battle. He has very simple attacks and he doesn't make you wait with patterns until you can hit him.

Chaos starts by just approaching you slowly until he can reach you for his arm stretch attack. Simply use Homing Attack on him before he attacks. After taking a hit, Chaos then spins himself really fast towards your direction with his arms out as an attack. Jump high to avoid the attack and to get to his weak point and hit him again. After the second hit, Chaos jumps really high up to go on top of the surrounding light poles. He will keep jumping on the poles from one to another to get to pole nearest you. You can keep running and he'll never come down so you can finish him off so just let him get to the pole near you and he'll do his super arm stretch attack which you can easily dodge but you have to stay near the pole he attacked you from so he has no other option but to come down. He'll do another arm stretch attack once he gets on the ground but just finish him off before he does.

Once Chaos is defeated, he turns into a water puddle and goes down the drain.
