As far as physical attackers go, Slowbro fears Scizor and Breloom alone (remember that CB Kyurem calc? Fusion Bolt does a max of 88%)
I apologise if this is nitpicky in any way, but quite frankly, taking 80-88% from Kyurem-B is something that would reallly scare the shit outta me. By all means mention that it can tank that hit, but implying that Slowbro doesn't fear Kyurem-B is potentially a little misleading.
Also potentially worth mentioning that Sub DD Gyarados (its only really mentioned as something Psyshock hits rather than something that gives Slowbro trouble) could potentially cause it problems if it lacks a Psychic attack, and I guess Tyrantiar are the other physical attacker thats a little worrying that Slowbro "potentially" fears.
Assuming you fix that bit up a little bit
