Game:Xion



Xion is fought as a boss several times in Kingdom Hearts 358/2 Days. She is fought as the game's penultimate boss.

Kingdom Hearts 358/2 Days
In Mission 75, Roxas is sent to Twilight Town. Xion has left the Organization and is mistaken for the Organization impostor, Riku. Roxas has to track her down and "eliminate" her. Roxas attacks the imposter, but is stunned to realize he is fighting Xion.

She attacks Roxas in Mission 92, which takes place throughout various locations in worlds visited during the events of the game. Using the Organization XIII Devices, Xion is able to absorb Sora's memories from each world in order to replicate his abilities, and to some extent other elements of those worlds. For example, in Halloween Town, Xion uses Sora's Ragnarok and uses a weapon resembling the Chimera arm or The Experiment's arm, while in Agrabah, she uses his Ars Arcanum and has arms and swords resembling Kurt Zisa. Strike Raid is the only one of Sora's Kingdom Hearts special abilities that Xion does not use. Interestingly, the first three areas that Xion warps Roxas to are the locations of that worlds' respective Keyholes. In the case of Twilight Town, the Station Plaza is where Sora opens the world Gate.

Design
During Roxas's battle with Xion, she dons armor which changes a number of times throughout the fight. Her basic form is a bizarrely-shaped, predominantly silver and black suit, with dull red armor near her waist, gold on her boots, and orange armored gloves. Xion's helmet sports two black spikes that jut out horizontally on either side, and a large, red Nobody symbol on the faceplate, part of which forms something of a horn on the top of the helmet. This form is based on Sora's original appearance, with Sora's jacket, pants, and necklace, although Xion's pants are pink and have designs, and her necklace features a Nobody symbol instead of a crown.

In her first form, Xion sports large, skeletal, colorful wings and a huge, orange and red, intricately-shaped sword. In her second form, Xion loses her wings and grows to twice the size of Roxas, exchanging her sword for a large, pincer-like weapon vaguely resembling one of the Chimera's arms. In her third form, Xion transforms into a figure with four huge arms, decorated with elegant gold, purple and red designs. She has large blades instead of hands, and her arms resemble Kurt Zisa's arms. Her main body is slightly larger than normal in this form.

In her final transformation, Xion grows to a titanic size, about the same height as the Train Station tower in Twilight Town. Her armor is now embroidered with numerous spikes and ribbons, and she gains two pink and silver, Keyblade-like weapons with teeth in the shape of the Nobody symbol. Interestingly, this form has a similar design to Sora's appearance in Kingdom Hearts II, now being mainly black and dark grey.

Mission 75
Roxas may get stuck fighting the many Heartless in this mission during the search for Xion. Moving further into the Tram Common, Roxas sees Xion on top of a building, and she runs away. Xion does not attack, but only runs and dodge rolls, and teleports to another place in the area after taking several hits. The system for when this mission ends is unclear, as the timing for Xion to go to the secluded area is set at random. At the end of the mission, Xion teleports herself to the secluded place, where she waits for Roxas. Once Roxas reaches Xion, the mission ends, following a few cutscenes.

Mission 92
Be prepared for a multi-stage boss battle. During the fight, Xion transports Roxas to four different locations, each time assuming a different form.

Xion possesses two unique abilities during her first three phases.

Counter Slash: When Roxas parries a combo attack (i.e. using Block), Xion performs an unblockable counterattack. Dodge Xion's attacks instead of Blocking.

Barrier: When her HP is low, Xion occasionally attempts to restore her HP. She floats into the air, channels for a couple seconds, then raises a dark barrier, becoming temporarily invulnerable and regaining a substantial amount of HP. Interrupt this ability by attacking Xion before she raises her barrier.

Xion's attacks require good timing and careful maneuvering to avoid. Make good use of Dodge Roll and Glide. Equip Cure magic and/or Potions. Attack magic is effective but not essential.

First Form
The first battle with Xion takes place in the Bizarre Room of Wonderland.

Continuous Slash: Xion's basic combo attack. Xion performs an overhead slash, then a forward thrust, then a spinning overhead slash.

Tame Slash: Xion charges energy, then performs a rapid forward thrust.

Sonic Blade: Xion's aerial attack. Xion enters flight mode by first pushing Roxas away with a nondamaging burst of energy, then floating into the air. Once airborne, she performs Sora's Sonic Blade, attacking with a quick diving thrust.

If Sonic Blade connects, Xion repeats the attack until it misses or is parried. Xion returns to the ground after the attack.

Second Form
The second battle takes place in Halloween Town, at the Manor Ruins.

Continuous Slash: Xion's basic combo attack. Xion performs an overhead slash, then an upward diagonal slash, then a forward thrust.

Tame Slash: Xion creates a vortex to pull Roxas in, charges energy for a number of seconds, then performs an overhead slash. Escape the vortex by Gliding or Air Sliding. Alternately, Dodge Roll the moment Xion performs her overhead slash.

Ragnarok: Xion uses Sora's Ragnarok. She floats into the air, charges energy, then fires a salvo of projectiles which home in on Roxas. Avoid this attack by Gliding or running away (with a level 2 Haste equipped) until the projectiles disappear.

If Xion performs Ragnarok repeatedly, land one or two attack combos while she is charging, then immediately move away. If dodging proves difficult, consider equipping a ring with Nil resistance such as Nothing to Fear to mitigate Ragnarok's damage. Note that although Nothing to Fear fully nullifies Ragnarok's damage, the missiles still stun Roxas if they connect.

Third Form
Xion's third battle takes place in the Lamp Chamber area of Agrabah. In this form, Xion is more graceful and agile, performing flips and spins that make her difficult to hit.

Continuous Slash: Xion's basic attack. Xion performs two downward diagonal slashes with her front blades, then a slow overhead slash with all four blades.

Tame Slash: Xion creates a vortex to pull Roxas in, charges energy for a number of seconds, then slashes with all four blades.

Jump Attack: Xion leaps into the air, plunging downward with multiple slashes and producing a small shockwave.

Ars Arcanum: Xion infuses all four blades with light. She performs two downward slashes, a jumping slash and a downward strike, then a leaping flurry of slashes.

Xion's third form is arguably the most difficult form to dodge due to limited dodging room combined with Xion's agility and long reach. Land combos immediately after she stops attacking, and move away before she resumes.

Final Form
The final battle with Xion takes place in front of the Train Station in Twilight Town. She becomes massive, but remains stationary at one end of the battlefield throughout the fight. In this form, Xion loses both Counter Slash and Barrier, and her regular attacks are slow and telegraphed. However, her attacks can inflict status effects.

When Xion raises one blade, she performs either Continuous Slash or Continuous Rush.

Continuous Slash: Xion's basic attack. Xion performs a slash with each of her blades, then a slash with both blades.

Continuous Rush: Xion slashes four times. Each slash creates a shockwave of blue energy.

When Xion crosses her blades, she executes either Gravity or Laser.

Gravity: Xion creates an orb of darkness near her.

Laser: Xion fires blasts of light from her shoulder tendrils.

When her HP is low, Xion gains access to two powerful desperation attacks. Which one she uses depends on whether her previous attack was Gravity or Laser.

Laser Rain: Telegraphed by Laser. Xion creates a vortex, puts her Keyblades together, and fires a blast of light into the air, causing pillars of light to rain down randomly across the battlefield (Laser Rain is based on dual-wielding Roxas's limit break: Magic Hour). Avoid by Gliding as close to Xion as possible, where the attacks are less likely to hit.

Final Limit: Telegraphed by Gravity. Xion creates a massive pillar of light which engulfs most of the battlefield. Glide against the corners to the east or west of Xion. (Final Limit is based on Trinity Limit.) Alternately, equip Nil resistance to mitigate or prevent damage.

Memorizing how Xion's telegraphs each attack can be useful, but is not necessary: in this phase, all of Xion's non-desperation attacks can be safely Blocked. Glide to dodge Xion's desperation attacks.

Trivia

 * During the battle against Xion: First Form, Roxas has been shrunk down despite not drinking the potion, and also grows back to normal size when he is transported to the next stage, again without drinking the potion. Xion also changes sizes in the same way without explanation.
 * "Vector to the Heavens", the music that plays during Xion's final form, is a mix of Kairi's Theme, Musique pour la tristesse de Xion, and Dearly Beloved.
 * During Mission Mode, while battling Xion, she will not speak, due to some of her battle quotes being about Roxas.
