Atmospheric Pressure

Atmospheric Pressure is the fourth boss in Crash Bandicoot: The Wrath Of Cortex and is also the last Elemental battle before Crash can rumble with Dr. Neo Cortex in the space hub. After Crash has collected all of the Crystals from the air hub of Coco's VR Hub System, Crash will be allowed to battle Crunch who is partnered with the Air Elemental, Lo-Lo. Up until this point, all of the boss battles have taken place on solid ground, but this time, Crash and Crunch take the arena up to the skies and the background seems to be located up above villages and somewhere mountainous, as mountains can be seen here, too. As opposed to the other 3 Elemental battles (and the final confrontation after this boss battle), there are no phases, so this is the only battle that is straightforward attacking Crunch with the help of Crash's Glider while dodging Crunch's attacks (which are described below this). After Crunch's health is emptied out, Crunch's genie-like body vanishes and Lo-Lo is once again trapped in hibernation alongside the last 3 Elementals before him. The duo leave nothing else behind but the ability that allows Crash to use Wumpa Fruits as ammo to hit faraway objects.

Attacks

 * Flying ball: The first basic attack. It is literally a ball that flies from the right side of the screen to the left. Relatively easy to dodge but can be a pain if unprepared.
 * Laser: A continuous beam from Crunch's right hand. Although it follows you around the screen it is slow and therefore easy to dodge. However it does large amounts of rapid damage otherwise.
 * Multiple balls: Crunch shoots a barrage of energy balls from his eyes at you.
 * Lightning: Electricity radiates from Crunch's chest and releases lightning with a small gap in between. It progresses down the screen. To dodge this you must quickly get into the gap.
 * To hit Crunch, you must hit the body part which Crunch uses to attack you. Lo-lo will indicate which attack Crunch will use so you know where to hit straight away.

Trivia

 * This is considered to be the hardest boss in the game by some fans, although others consider it to be the easiest boss. Even more fans believe its difficulty is somewhere in between.
 * This is the only battle in the game where Crunch seems to die, since his body explodes and his skeleton is shown.
 * This battle is somewhat similar to N. Gin's battle in Crash 3. Crunch's left arm (right to the player) launches a ball, Crunch's right arm (left to the player) launches a ray of light (like the Gatling Gun in N. Gin's battle), Crunch's head launches multiple balls at the player (like N. Gin's missiles, but these orbs don't home in on the player) and Crunch's stomach launches a wide ray that falls from the top of the screen.
 * This is the only boss to be fought in the Glider.
 * This boss has the most health in the game as it takes 100 hits(25 hit points per limb) to defeat it.
 * The music of this boss is a possible remix to "In Hall Of the Mountain King".
