What are Your Top 20 Favourite Pokémon?

Here's an idea: list your top favourite Pokémon, as well as what you like about each of them. Your list must include:

●One non-Legendary, non-Mythical Pokémon of each type
●One Legendary Pokémon
●One Mythical (event-exclusive) Pokémon

For dual-type Pokémon, put them on your list as either type, but not both; ie. if Gengar is on your list, add it as either your favourite Ghost- or Poison-type, and add a different Ghost- or Poison-type as well. Have fun, and remember to respect the opinions of other posters.
