We have one for Pokémon that know moves they shouldn't, why not one for Pokémon that don't know moves that they ought to?
- Weezing eats garbage. Gunk Shot involves the user spewing garbage at the opponent. You would think, given these facts, that Weezing would be able to learn Gunk Shot. You would think.
- Weezing and Gengar can only have Sludge Wave from the Dream World (and that one Shiny Gengar event)- they cannot learn it from a TM.
- Snorlax can't learn Slack Off, despite how lazy it is.
- Ampharos's tail gives off light, so does it learn Tail Glow or Dazzling Gleam? Of course not!
- Weedle's Hoenn Pokédex entry praises its sense of smell, and yet no Odor Sleuth for it.
- Wobbuffet doesn't get Bide.
- The Pokédex confirms Yanmega can support an adult in flight. With that in mind, you would think it would learn Fly. You would think. Meanwhile we got tiny stuff like Spearow and Fletchling carrying their Trainers across the sky...
- Electrode is heavily implied to be basically a sentient Poké Ball, so... wouldn't it make sense for it to learn Growth and Minimize?
- Samurott ought to get Sacred Sword.
- Dedenne's only attacking Fairy move is also the only physical Fairy move, despite its superior Special Attack. Give it Moonblast, or Dazzling Gleam, or Draining Kiss, or something!
- No Glare for Onix or Steelix.
- I was truly stunned to learn that Helioptile, despite getting its energy from the sun, cannot learn Solar Beam.
