Light Capsule

The Hidden Capsule Items are recurring themes throughout several of the Mega Man X (series) games. They are all Dr. Light capsules that are hidden well within one of the stages of the Fortress of the game, and have a certain requirement for the capsule to appear. The first two Hidden Capsule Items bestow X with a powerful attack, and the subsequent two grant X with a powerful armor.

Hadouken
The Hadouken Fireball is a small joke from Capcom included in Mega Man X and Maverick Hunter X. It is based off of the Street Fighter attack, the Hadouken, and is executed in the same way. While X's health gauge is full and he is on the ground, input the combination: DOWN, DOWN-FORWARD, FORWARD, FIRE. X should unleash a powerful fireball. It can kill many bosses in a few hits.

To obtain the Hadouken Fireball, obtain every Sub-Tank, Heart Tank and Armor Capsule. Play through Armored Armadillo's stage until the last rolling platform. As the platform bursts out of the tunnel and through the sky, dash-jump off of the platform and ascend the wall right on top of the gate to Armored Armadillo. There should be an energy pellet. Depending on what console you play this on, instructions will differ from this point:


 * SNES, PlayStation 2, GameCube: Collect the pellet and jump into the large bottomless pit, and repeat until Dr. Light's capsule appears next to the pellet.
 * PC: X must have a full energy gauge and Sub-Tanks before he reaches the energy pellet to get Dr. Light's capsule to appear.
 * PSP: X must take no damage from the time he dies and teleports back into the stage to the moment he touches Dr. Light's capsule.

Shoryuken
The Shoryuken Fireball is another technique based on a Street Fighter attack, the Shoryuken. It is executed with FORWARD, DOWN, DOWN-FORWARD, FIRE while X is at full health and on the ground. X will surround his arm with fire and perform a powerful uppercut, causing massive damage to its targets.
