Joker: Love him on principle alone. While he's a bit too "precise" for lack of a better word for my tastes, and while I never played Persona 5, I can definitely respect his inclusion, and the team did a great job with his moveset. B
Hero: I can only play Hero if I'm going into it as a ****post, but that's not a bad thing, Hero is so stupid but a good kind of stupid, I adore how bonkers they went with him. Hero dittos are almost their own mode. B
Banjo & Kazooie: Easily my favorite Fighters Pass character. While I never played Banjo-Kazooie until very recently nor really wanted them like I did with Ridley and King K. Rool, there's just something so special about seeing a fan request whose been MIA for years finally make it into Smash. And while they are admittedly clunky at first and hard to get used to, they are extremely fun and versatile. S
Terry: My least favorite Fighters Pass character. I don't hate him nor do I think he shouldn't have been included, and I do like the ideas his moveset introduces, but his playstyle just isn't for me and the button inputs are too hard for my puny brain to wrap around. D
Byleth: I'll need to wait for them to release before I give them a final judgement, but Sakurai really sold me on them. I was initially iffy on Byleth, not that I disliked Fire Emblem or anything, the character just didn't interest me. But seeing them in play made me really excited to pick them up (plus them being revealed on my birthday gives them a bit of personal connection to me, more than I can say for than any of the other Fire Emblem characters). A for now until they release and see them for myself.
Overall? Pretty solid A. While Byleth is kind of a weird pick to end on, it's overall a really good, diverse lineup. If the second Fighters Pass is like this, I'm very much looking forward to it.
