Super Smash Bros. Ultimate (Ridley Me This)

His jab would unique. I don't believe other smash characters have too much variance in their jabs - I know with Falcon you can do an alternate combo with a different timing - so with his jab I'd let him do several of his staple combos from DMC3/4 with consecutive A presses of different times/pausing in between some presses. (Don't know too much about Bayonetta, but apparently she only as one additional jab combo).

Forward-tilt - easily would be his standard swordmaster attack, spins his sword in front of him. Multi-hits to end a damage-combo as opposed to a kill-combo.

Up-tilt would be high time, an sword uppercut that lifts opponents for combos. Like in DMC, holding it will make Dante go up with the enemy, making follow-ups easier.

Down-tilt - While for simplicity's sake I imagine most of Dante's moves being carried out by his sword Rebellion (but there'd be room for other weapons with Custom Moves), I'll throw in a reference to Beowulf for his d-tilt. Just a sliding kick, similar to Cloud.

Neutral-air - Aeriel Rave, sword slashes which suspend him in mid-air.

Forward-air - Helm-breaker, falls down forward with his sword (like the falling part of Ike and Cloud's Up-B)

Down-air - Spins around upside-down while firing his guns. From DMC2 which is a pretty bad game, but that move did look cool, and it'd be a somewhat unique down-air.

Up-air - Upwards spinning attack with Cerberus, the ice-nunchucks. A bit unsure about this one, but again, I think it'd look cool.

Back-air - Shoots his guns behind him, inspired by his Gunslinger style.

Dash-attack - Stinger, plunging forward with his sword, and if you mash A while you do it, it transitions to Million-hit stab, a multi-hit stabbing move.

His smash attacks I'm not too sure about. Maybe they'd be carried out by Sparda, from the original DMC. Those attacks extended out and packed more of a punch than any other weapon in that game.

Neutral B - gunshots.

Side-B - Trickster, essentially teleport left or right, for recovering and general movement.

Down-B - Devil trigger, makes you stronger for a while and is charged similarly to Cloud's limit I guess. Up-B - idk, some sort of sword leap.

Maybe give him a grapple recovery based off his DmC grapples as well. Small shoutout to that game.

Costumes: his popular young Dante look from DMC3 would be his main design, then I guess his costume from DMC since it's had a couple of appearances. Not sure. Palette swaps that reference the other games if there isn't enough development time/desire for proper models.

These are mostly of the top of my head and I'd easily change a lot of this with more thought, but yeah, you could do a lot with Dante.

It's Byleth.

I loved FE:TH, so I'm not disappointed to see it represented, but I'd have preferred other characters over the player avatar. Fuck it, I'd have taken all three House Leaders, Byleth and Lady Rhea as a full Fighter Pass.

This is a really lame end to the pass for me for a couple of reasons, fire emblem is already over represented in the game & yet again it's barely a character given that they're a silent protaganist in FE3H. (no idea if that changes since I haven't played the game)
Those that have played it talk way more about all the other characters which would've been a much much better choice, let's take Drunka's 3 house leaders idea and imagine how they could've made a fire emblem style Pokemon trainer fighter instead...........but it is what it is and I never bought the pass anyway so I've actually saved money just buying the ones I liked the look of. (Terry, Joker & Banjo)  
 

there are now 8 Fire Emblem characters, who I'd argue are interchangeable pawns, and only 6 Zelda ones, 3 of which are Link - I already can't remember who's who
