Geno - 10/10! Truth be told, I've yet to play Super Mario RPG, but after Ridley and K Rool being revealed, I've been wanting that trinity to become complete with my favourite design of the three. Plus, I've been a Smash fan since Brawl, so I've seen the Geno speculation for close to a decade now.
Isaac - 5/10. Truly neutral, on account of not having played Golden Sun. Good for his fans, though.
Banjo and Kazooie - I'm not a Banjo Kazooie fan at all please don't hurt me I just don't like the aesthetic particularly Banjo's design so 2.5/10
Chorus Kids - I enjoy Rhythm Heaven well enough. I'm a big rhythm game fan, and I particularly prefer more traditional ones, so I'm a little biased against it, but I'd still be happy with it getting repped. 7/10.
Ken - Partner is a big Puzzle Fighter fan, so I've got an attachment to Ken seeing as he's the highest tier character in that. Not my favourite SF character, would prefer Chun-Li, Blanka, or Juri, but I'm not going to be upset. 6.5/10.
Shadow - I adored him as a kid. I always liked the edgier equivalents to the main character, for some reason - Venom, Meta Knight, and of course, Shadow. I have a lot of sentimentality towards him, so 9/10.
Mach Rider - This is our only chance at a retro rep unless we get a Super Street Fighter-esque rerelease of the game, and while there are other characters I'd prefer, such as the Satellaview Mascots, Disk-kun, or Jerry Boy, I'm happy with this. 8/10.
