Hyde Bohr (boss)

This battle is the entire playable section of Episode 6 (excluding the final scene with Aya and Eve). There are two parts to this battle:

First, after a cutscene, Hyde starts to glow and starts to Overdive into the multiple people seemingly frozen in time around the area. Hyde appears the same as when Aya fights him in Episode 5, albeit with a skin effect similar to Antibody, or perhaps the ghost form of a Mudflap. His attacks are also the same. Aya can kill Hyde easily, but he'll then dive into another body, though not immediately. While it is possible to defeat him in this stage, it is extremely difficult to do without heavy firepower and quick reflexes when he Overdives, a feat which becomes virtually impossible on higher game difficulies. Consequently, the "intended" way to proceed is for Aya to be killed by Bohr.

Note: The aiming system will target the frozen people Hyde can dive into. This can be frustrating when trying to target Hyde in the next section.

If Bohr is not defeated before killing Aya, after an unskippable cutscene, Cray, Kyle, Gabrielle, and Blank will start to hover in a circle around Hyde. Hyde's supply of Overdive subjects decreases to about two in the entire area (they are still replaced when used), while Aya can now dive into her four friends, whose tracking of Bohr makes targeting him considerably easier.

Strategy

It is recommended to use the Overdive Target's weapon as it has infinite ammo. All of them have the same assault rifle that fires 30 rounds. As they follow Hyde, Aya need only dive to catch up to him as he distances himself from her. He will usually use a close combat attack, so just dive to escape harm. This works for his energy shots as well.

Another cutscene and Aya is within Hyde's psyche (needs verification) where Hyde has transformed into his true High One form. During this time Aya is permanently in Liberation mode, with the Libration Bar representing Aya's Health. Here, Hyde attacks with balls similar to a Big Energy Shot of varying sets: multiple sets of three fired in a rhythmic beat, straight forward rapid fire, and conjuring a large set of 6-10 that sends three or more at once in rapid succession. Hyde also charges at Aya which can be hard to avoid if not timed just right, and can also come up close to send a "ghost" at Aya, sometimes in sets of three.

Just keep firing at Hyde while avoiding his attacks. The ghost and charge do the most damage; to avoid them, dodging at the last second works as well as just running to the side. That means not locking on. The Energy Shot may still hit even if dodged.
