Striker Backdash
Gohan's Backdash has a bit more to it, since it puts him high into the air rather quickly and then you're able to airdash or even throw out one of your strong aerial kicks!

Double Airdashes
More exceeding mobility features for Gohan, he can perform an airdash twice in a single jump, unheard of! Not only that, but in Unleashed Mode he gains access to airdashing into the six other directions (up, down, and all four diagonals). UNHEARD OF! He can also dash-cancel out of a lot of moves, try out which ones for yourselves!

Wall Cling
When you're airborne and close to the rear wall, press Back then Forward and Gohan will cling onto it for a hot second. After that, he'll automatically airdash off the wall diagonally downward. You can do this prematurely and manually by pressing down. Alternatively, you can double-tap Forward to airdash off the wall straight ahead.
Standing Medium Kick Chain
Standing combo extender.
Wing Kick
Combo-ender. Twist-knocks-out the opponent on impact.
Launcher Kick
Main tool for launching enemies into the air after which you can persue them (by pressing Up) with an aircombo. There is a running version of this, performed by f,f+SK, which can combo off the Focus Attack.
Jumping Medium Punch Chain
Air combo extender.
Elbow Drop
Gives you a little upwards nudge while performing a downward-directed attack. You're able to extend the attack by holding down the Medium punch button all the way until he lands on the ground. Acts as a regular jumping Medium Punch and thus is chainable into a jumping Strong Punch or Kick.
Jumping Medium Kick Chain
Air combo extender.
Butterfly Smash
Main tool for smashing opponents down to the ground during an aircombo. If an aerial opponent is hit by this move, they'll fly to the ground and bounce up upon impact, allowing for a juggle combo.
Omni Kicks
Gohan has the unique ability to kick into any direction with his Strong Kick while in the air. The down-forward, down and down-backwards versions cause a ground-bounce, while the forward, up-forward, up-backward and backward versions cause a twist-knock-away. The up version causes a flip-knock-out. You can add one of these kicks after a regular jumping Strong Kick.
Slashing Kick
Running attack, combo starter. Used to be able to combo off the Focus Attack but it can't anymore!
Ki Blast
Gohan fires a large basic Ki Blast that disappates after a while. The speed the blast travels at is determined by the strength of the button input: Weak version travels slowly, while Strong version travels fast. Medium as usual is somewhere inbetween. Also the stronger button is used, the farther it will travel before disappating. You're able to shoot two Ki Blasts, one after another. You can mix up the Weak, Medium and Strong versions. The EX version has Gohan firing two Ki Blasts consecutively automatically which launches the opponent up with an explosion and you can combo the normal version into the EX version. The second time you use the EX Ki Blast in a combo, it launches the opponent less high and they can tech out of it as well. The EX version doesn't have the f+P follow-up blast.
Hurricane Kick
Different from Goku's though it shares the same name. Gohan's variant has him traveling more at a forward arc. Weak version does one kick, while medium does two and strong does three. All versions knock the opponent away. You can supercancel into the Super Flurry Kick during this. EX version knocks the opponent away harder and bounces them off the wall, allowing for juggling.
Rising Hurricane Kick
Anti-air, diagonally rising version of the Hurricane Kick. Gohan is invincible until slightly before the 1st hit and thus it can act as a reversal. Weak version does one kick, Medium does two and Strong does three. All versions knock the opponent up and away. You can supercancel into the Super Flurry Kick during this. The EX version kicks even more times and carries the opponent all the way into the air with you.
Diving Kick Flurry
Piccolo's teachings are showing here, as he adapted one of his famous moves. Starts as a single dive kick, which if it hits, sees Gohan performing a flurry of aerial stomping kicks ending with a knock-away kick and having Gohan rebounding with cool backflips.
