Dark Determination

"I'm not wavering anymore."

- Johnny to Gyro, SBR Chapter 59

Dark Determination appears to be phenomenon or state of mind which can manifest within the JoJo universe. The afflicted is able to completely put aside their sense of morality to kill or protect a person. The trigger for its occurance depends, but it is normally activated when one is desperate to attain a specific goal. When one achives Dark Determination, they will also become more ruthless and cold-blooded, using any means necessary to complete their objective. Dark Determination can be acquired regardless of Stand User status.

The idea of Dark Determation is likely the center of Ringo Roadagain's, "The True Man's World," philosophy. Not only is Ringo the first person to identify the phenomenon occurring, but also it was only after his own initial experience of Dark Determination that he created the philosophy.

Appearance
Dark Determination takes the form of a fiery aura in their eye. Weather Report's version takes the form of thunderclouds, thought it could be a design choice in itself. Generally, the fire is the same colour of their iris, though sometimes it's the pupil. It's either a lighter or darker tone, the former being more prominent. Sometimes, the colour completely changes, as seen with Josuke and Jolyne. The same goes for the (debatable) anime instances.

Ability
Dark Determination seemingly throws away their morale compass and sense of mercy and turns them into cold-blooded murderers. As stated by Gyro, "The user's eyes are the eyes of a killer.". This is because, under its effects, the user will show no hesitation in committing heinous crimes to achieve their goal, if not just outright murder. This makes the ability rather powerful, though it could also get them into trouble due to being completely unhinged. It is unknown if the ability boosts a person's power, but the combination of the user's will to kill (See what I did there? Hah.) makes their chances of winning way higher than normal.

Game Appearances
Dark Determination appears in JoJo's Bizarre Adventure: All Star Battle as part of Johnny's HHA, where his stand changes from Tusk Act 2 to Tusk Act 3. It also appears in JoJo's Bizarre Adventure: Eyes of Heaven, once again associated with Johnny.

Users
The form is actually usable by anybody, as it is merely a state of mind. Despite this remark, only a few people have visually be shown in this mindset (This does not mean nobody gets angry in JoJo). The following is a list of all the seen Dark Determination users (Take note only the appearances in the manga are 100% authentic, the rest could just be a design choice.)
