Anyways, what characters do you want for the 2nd season?
Here's my wishlist...

Love at First Fight
Chi-Chi
Videl
Both these girls got together with their men through fighting. Anyways, what Chi-Chi and Videl could add to the game is genuine melee-focused characters (FighterZ already toys with the idea through Gohan (Teen), Yamcha, and Bardock) like them having something unique to them for the S Button instead of a generic blast. Chi-Chi would be based stances and footwork while Videl is more about sways, step-ins, and grapples.
Dragon Ball
Master Roshi
Out of all the original Dragon Ball reps to be in this game, it absolutely has to be Master Roshi mainly due to his major comeback in the modern stuff. Even ignoring the current stuff, Roshi has a plethora of interesting techniques including the Drunken Fist, MAX Power, Evil Containment Wave, Turtle Shock Surprise, and Hypnosis.
Fusion Reborn
Gogeta (Super Saiyan)
The less popular of the fusions between Goku and Vegeta, but he isn't without moveset potential. While Vegito is a more balanced fighter, Gogeta is all about being on the pressure with his super swift punches and weird mindgames. Soul Punisher could also be used like a time bomb that will wipe the opponent out completely if they don't land a hit.
Hell Fighters
Dabura
Janemba
These two are very similar- both are insignificant side villains in the grand scheme of things but have won hardcore fans over with their cool designs and unique abilities. Dabura can materialize a sword or a spear from thin-air plus he has flame breath, air slices, and can turn people into stone with his spit while Janemba can use dimensional holes both offensively and defensively, create ki crescents from his sword slashes, rapid thin-shards of ki, and teleportation via atomizing himself into cubes for mixups.
Tournament of Power
Caulifla
Jiren
Caulifla is the face of the female Saiyans and she comes paired with Kale but unlike other characters with unique assists, Kale would be there to help out at any time. Caulifla is the brains of the team and does most of the fighting (evidently) while Kale is the muscle. Jiren is pretty much the main antagonist of the arc and he would be a defensive character who strikes really hard dealing great damage when the opponent is wide open. He would also be really good at dealing with opponents in the air.
Aside from the roster additions... I would like to see some alternate costumes for the game like Goku (Super Saiyan) wearing his casual Cell Games outfit or his battle worn orange gi. Maybe an option for different announcers.
