Dark Baymax

Dark Baymax is a boss in Kingdom Hearts III. It is the original Baymax, corrupted by darkness.

Kingdom Hearts III
Dark Riku takes the combat chip from the original Baymax and places it in the Darkubes to gather data on hearts as part of an experiment to see if a heart can be created from data. After the Heartless steal enough hearts and cause enough panic throughout San Fransokyo, Dark Riku takes the combat chip back and summons the original Baymax from the alternate dimension, placing the new data inside the empty shell. The Darkubes fuse with Baymax, creating a warped and evil version of the armor the second Baymax wears. Sora and Baymax 2.0 fight Dark Baymax until it is put under enough stress to force it into stasis mode. Hiro Hamada takes out the chip and crushes it. He later creates an identical Baymax program chip to turn the original back to normal. This Baymax is later seen as part of the team.

Design
The armor worn by Dark Baymax is purple and fuchsia, as apposed to the red and blue armor worn by Baymax 2.0. The shoulders have spikes, while the visor has horns and purple eyepiece hiding all but the red glowing eyes of Dark Baymax. Contrary to the streamlined wings of Baymax 2.0's armor, Dark Baymax's end in ridges that resemble feathers. The most distinct difference is the large right hand made of Darkubes replacing the gauntlet Baymax lost; it periodically pulses with red energy.

Strategy
Because Sora spends the entire fight in the Interceptor Wing Team Attack, he cannot use magic, Formchanges, items, or Link Summons. However, for this fight only, Sora can use Baymax's Care Spray ability to heal.

The first phase begins with an on-the-rails shooting segment, in which Sora and Baymax pursue Dark Baymax through the streets. Sora can use the Shoot command to open fire on Dark Baymax. Throughout the segment, Dark Baymax attacks by summoning Darkubes; the transparent ones can be destroyed while the more solid ones can be repelled back at the boss to deal damage with the Strike command.

The second phase begins when Sora and Baymax corner Dark Baymax in the South District. Dark Baymax has a myriad of attacks in this phase, being able to perform a three-hit combo, rush at the duo, fire a beam of darkness, or summon Darkubes to attack. Throughout this phase, Sora has access to the Sky Strike Situation Command, which is identical to Interceptor Wing's finish command. Gaining access to this Situation Command involves either unleashing physical combos on Dark Baymax, or parrying the solid Darkubes back at the boss. It often tends to attack aggressively, so be ready to dodge if it approaches Sora and Baymax. The most important thing to note is to keep firing at Dark Baymax, dodge if necessary, and build up Sky Strike to deal damage.
