Bolt the Cat
Bringing the Thunder
I thought that was kind of stupid. Why have any of their forms in it at all >.>
Some of them can be seen on trainers' rosters, but some cannot. I do think a few of those could be placed earlier in the game, for instance, put Blitzle in Virbank Complex, Golett in Relic Castle or Celestial Tower, Shuppet in Celestial Tower, Wingull on Driftveil Drawbridge (seriously, why is Ducklett the only Pokemon you can catch here, seems really pointless).
