Jonathan is of the Ripple User (波紋使い, Hamon-tsukai) style, which allows him to charge the Ripple Gauge that determines the strength of his attacks as well as do more and unhealable damage to Vampire and Pillar Man characters.
Most of his moveset and character model remain the same from All-Star Battle. New additions to Jonathan's attacks include him using the spear he attacked Dio with shortly after his transformation as a Powerful Attack. Several of his new combos and sidesteps are now based on his boxing skills displayed during his childhood.
Style/Specials/etc
Ripple Breath
ON GROUND CHARGEABLE
Jonathan performs a pose and Ripple Breathes, filling up the Ripple Gauge. He cannot move and is vulnerable to attacks while doing so. Filling up the gauge will passively strengthen his Normal and Powerful Attacks, and enhance/alter the properties of all his skills. It will also shorten the cooldown time on said skills. Using skills will drain a portion of the Ripple Gauge until there's an insufficient amount to use.
My Final Ripple...
ON GROUND
When Jonathan's health hits zero for the first time, if his partner is still alive, he will be granted a decent portion of continuously draining health to continue on. All attacks and skills are unusable, leaving Jonathan with only a special final attack in which he attacks with crossed fingers, dealing considerable damage. Once his health reaches zero once more, or if he successfully lands his final attack, Jonathan will formally be Retired.
Skills
Zoom Punch!
+ ON GROUND
Jonathan slides forward and hyperextends his arm to punch at great range.
Ripple-enhanced: The skill will execute quicker and Jonathan may chain follow-up attacks from it.
Overdrive Barrage!
+ IN AIR OK ON GROUND
Jonathan slides forward and unleashes a short flurry of punches ending in an uppercut. The last hit will send opponents flying. Jonathan may perform this in mid-air. This skill's damage is proportional to how much of the Ripple Gauge is filled.
Ripple-enhanced: The skill will execute quicker, unleash more punches, and receive a damage boost.
Sendo Ripple Overdrive!
+ TRAP ON GROUND
Jonathan punches the ground and sends his Ripple energy spreading out over a wide radial area for a few seconds, damaging and crumpling opponents caught.
Ripple-enhanced: The skill will execute quicker, deal more damage, and have a larger area of effect.
Who'll be the Last One Standing!
+ TRAP ON GROUND
Jonathan punches the ground and sends his Ripple energy spreading out over a wide radial area for a few seconds, damaging and crumpling opponents caught.
Ripple-enhanced: The skill will execute quicker, deal more damage, and have a larger area of effect.
Ex - Sendo Ripple Overdrive!
+ EX SKILL TRAP ON GROUND
Jonathan will be invincible when first executing the skill. The Ripple wave will be unblockable, and Jonathan's recovery time from the skill is reduced as well, allowing him to immediately follow up. This is in addition to other benefits granted by the Ripple Gauge.
Ex - Who'll be the Last One Standing!
+ EX SKILL TRAP ON GROUND
The skill will execute even quicker than when Ripple-enhanced, has increased speed and distance of the dive, will make Jonathan invulnerable while he is diving, and receives a damage boost. This is in addition to the damage benefits granted by the Ripple Gauge.
Dual Heat Attacks
Sunlight Yellow Overdrive! (Solo)
+ ON GROUND
Jonathan forcefully kicks the opponent off their feet in the abdomen, before he proceeds to pummel them at different angles and knocking them into the air, all while reciting his signature lines. After charging up an immense amount of Ripple energy, Jonathan unleashes a rapid flurry of punches into the opponent as they fall towards him, ending with them spiraling away after a two-handed crossing punch. Compared to All-Star Battle, most of his speech is removed in favor of several grunts.
The two of them attack the opponent's head, sequentially with a Ripple-charged Zoom Punch from Jonathan and a Sendo Wave Kick from Zeppeli, before they charge up and run up to the opponent and unleash a double Sendo Ripple Overdrive-enhanced Zoom Punch into them, the two reciting the phrase commonly associated with Overdrives.

The information below derives from Eyes of Heaven which was not written and only supervised by Araki. As such, it may not be considered canon.
Giorno Giovanna: When the two are on the same team, Giorno will ask Jonathan everything he knows about DIO. If victorious, Giorno will mention that DIO is his father, surprising Jonathan.
Jotaro Kujo: At first it was upsetting that Jotaro referred to Jonathan as his ancestor. Later Jonathan felt in his heart that he was succeeding his own lineage, to the point of asking Jotaro to finish Heaven-Attained DIO in his place during the main story's final battle. Also, if Jotaro is Part 4 version, he mentioned to Jonathan's grandson and Jotaro's grandfather Joseph Joestar.
Joseph Joestar: Jonathan is impressed by Joseph's tactics and Ripple. He states that Old Joseph reminds him of his father.
Kars: Upon encountering him, Jonathan will recognize Kars as the one who created the Stone Masks and seeks to kill him and destroy the Stone Masks. Kars seeks to kill Jonathan simply because he is a Ripple user and later attempts to recruit him to his side, considering his death to be a waste.
