Eyes of Heaven/Diego Brando

Diego was one of the first characters confirmed to be playable in the game (alongside Jotaro Kujo, Joseph Joestar, Noriaki Kakyoin, Josuke Higashikata, and Rudol von Stroheim). He appears as the solo final boss for the game's first demo. As a Mounted Fighter, Diego is able to switch between riding atop Silver Bullet or moving on-foot. Also, as a Stand user, Diego is one of many characters with wildly varied abilities that grant him uniqueness in battle.

Moveset

 * Style Action - Scary Monsters: Diego switches between Human Mode and Dinosaur Mode, granting him different abilities and skills. While in Human Mode, Diego possesses the majority of his abilities, and acts like most characters. While in Dinosaur Mode, however, Diego takes his usual form of a Utahraptor, making all of his attacks unblockable (with the exception of "Dinosaurs!") and passively gaining super armor. This greatly enhances Diego's offensive capabilities, as his Normal and Powerful Attacks become exceptionally strong in addition to unblockable, while he himself will not flinch to most sources of damage. He receives a unique and powerful skill, "USHAAAAAAAA!". However, Diego is unable to guard, leaving him especially vulnerable to attacks like DHAs, with his only means of defense being a well-timed jump in those situations. He also cannot lock-on, activate Dual Combos or DHAs, grab ledges, or interact with stage objects. Diego's stamina gauge will slowly drain, automatically reverting him when it empties, and he cannot manually revert from Dinosaur Mode himself. Naturally, he can only mount Silver Bullet while in Human Mode. Certain skills by opponents that would grab/throw Diego, activate a special animation between the attacker and target, or are simply powerful enough to send him flying will automatically force him out of Dinosaur Mode. While in Dinosaur Mode, the color of the player's screen converts to a deep, blurry blue, with the other combatants colored in pink unless they stop moving. This style of view is similar to N'Doul's visualized sonar ability seen in the TV anime, and is meant to emulate the motion-based sight that Diego would have as a dinosaur.
 * Dinosaurs!: This is the only skill available in both Human Mode and Dinosaur Mode. Diego creates a small dinosaur that hunts down the nearest opponent or Diego's lock-on target and biting them 3 times before disappearing. As the dinosaur has the properties of a projectile, it can be deflected by any number of abilities that could do so to projectiles.
 * MUDA MUDAAAAAA!: Diego quickly leaps forward and performs a somersault, growing a dinosaur tail and whipping it downward. Opponents hit by the tail are slammed into the ground. Diego is invincible until the start of the attack. If used in Mounted Mode, this instantly transitions Diego into Ground Mode.
 * Gouge: Diego lunges forward into the air and unleashes a barrage of 8 claw strikes before landing. If used in Mounted Mode, this instantly transitions Diego into Ground Mode.
 * Are you ready?!: This skill is only available in succession after "Gouge" is used. Diego lands and follows up the attack by performing a powerful 3-hit combo that sends opponent caught flying with a final, two-handed strike.
 * Silver Bullet: Diego switches between Mounted Mode and Ground Mode. While in Mounted Mode, Silver Bullet has above-average mobility and jump height and can unleash devastating Normal and Powerful Attacks. However, his stamina gauge will slowly drain, automatically dismounting him when it empties. Diego's skills, with the exception of "Dinosaurs!", will transition him into Ground Mode. While in Ground Mode, Diego can interact with stage objects and grab ledges, as well as utilize his Style Action.
 * EX - MUDA MUDAAAAAA!: Opponents hit by the attack will now bounce into the air, and Diego can freely cancel the skill before he lands with Normal Attacks. This allows him to immediately and seamlessly combo his targets while still in mid-air.
 * EX - Gouge: Diego is invincible upon activation, and the skill deals more damage.
 * EX - Are you ready?!: The skill deals more damage.
 * USHAAAAAAAA!: The only skill aside from "Dinosaurs!" available to Diego in Dinosaur Mode. Dinosaur Diego leaps forward, and if he connects with an opponent, he will stomp and pin them to the ground with his feet, before proceeding to rapidly chomp them while they're down. He completes the attack by performing a backflip, whipping his tail to send the target flying. This deals a high amount of damage and can even hit downed opponents, in addition to the other benefits of Dinosaur Mode.
 * Dual Heat Attack - This is the "line" to the world I'm going to inherit!!: In Human Mode, Diego delivers a series of relentless claw-handed blows to his opponent's body. After partially transforming into Dinosaur Mode, Diego shouts that he's going to kill them and finishes his assault with a superhumanly powerful downward chop to cleave them down the middle (a reenactment of his lethal assault on Valentine).
