Perfect Chaos (Sonic Adventure/Sonic Generations)

Perfect Chaos is the final boss in Sonic Adventure, as well as the main (and only) boss in Super Sonic's story and overall the nineteenth (twenty sixth if counting the character battles and the two fights with the Egg Carrier).

Since today, Perfect Chaos has been praised by many Players for its qualities, and has been considered as one of the best bosses in the series.

As a whole

 * 1) Perfect Chaos has hands down the best design out of any boss in the Sonic series.
 * 2) The main theme, Open Your Heart, is a great song.

Sonic Adventure

 * 1) The gameplay for Super Sonic is very nice.
 * 2) To damage Perfect Chaos, you have to charge at full speed until Super Sonic's aura is blue, allowing you to charge head first through Perfect Chaos and "climb" towards his head, damaging him.
 * 3) The atmosphere is intense, taking place in a destroyed Station Square.
 * 4) Perfect Chaos has many flashy attacks, such as launching energy laser, unleashing water tornadoes, and firing an energy beam from his mouth.
 * 5) You have to gather rings to keep yourself in check, making this battle fairly challenging.
 * 6) You get a beautiful ending after the battle.

Sonic Generations

 * 1) An excellent remix of Open Your Heart plays during this battle.
 * 2) The design of Perfect Chaos has been up dated, making him even more intimidating then before.
 * 3) The battle plays very similar to the Adventure versions, but there are some tweaks that makes this battle creative.
 * 4) Instead of playing as Super Sonic, you play as normal Sonic, which shows of just how much stronger Sonic has become.
 * 5) You now have to mainly Boost to damage Perfect Chaos, unlike the previous versions where you have to charge up.
 * 6) Perfect Chaos has one new move, and that's using his tentacles as a projectile.

Bad Qualities

 * 1) Sadly, Perfect Chaos only has six Hit-Points, which is one less then both the Egg Viper and E-105 Zeta.
 * 2) Some attacks can get annoying, in the second phase Perfect Chaos will shoot homing lasers that will aim at Sonic.

Tips

 * 1) Try to gather a decent amount of rings, though don't be greedy, for you only have a limited amount to use them.
 * 2) Before you charge at Perfect Chaos, make shore that have a great speed, (which is tell by the blue aura around Sonic) as if you don't, then you'll pop out of Chaos
 * 3) An easier way to gain speed is by jumping, the game treats it like your jumping off a ramp, so it makes it easier to gain speed.

Trivia

 * 1) The final battle with Perfect Chaos in Sonic Adventure was meant to be even more challenging due to him having more hit-points and more attacks, but it was cut due to limitations of the Dreamcast.
