In the first episode of pokemon, Ash sees a Ho-oH flying overhead, yet it wasn't known about (at least by Prof. Oak) until the second generation of pokemon.

When Ash hatches a Pokemon egg and gets Togepi in "who gets to keep Togepi", the pokedex comes up with nothing apart from a name.

Are there any other pokemon we get to see prior to their generation's season of the anime? (Up to generation 5)

  • Do you want occurrences in side-media like *Pikachu's Vacation* too? (Ex: Marill, Snubbull) – looper Jun 17 '13 at 11:05
  • Sure, but mostly the main series – Toshinou Kyouko Jun 17 '13 at 11:15
  • I think as long as the series is going on, it fails at least point 4: http://meta.anime.stackexchange.com/questions/348/what-is-the-status-of-list-questions-on-this-site Also I don't know whether its reasonably scoped, as there could be too many occurrences. – looper Jun 17 '13 at 11:39
  • Limiting it to gen 5 Pokemon, does that work? – Toshinou Kyouko Jun 17 '13 at 13:11
  • @looper: I don't think there will be too many occurrences, and I also don't think it requires frequent update (maybe once a few years?). However, the scope is indeed quite big, considering how many years the series has been running. – nhahtdh Jun 17 '13 at 14:08

    @nhahtdh While it's hard to tell if that list is complete, you might as well post it as an answer since it's better than what anyone here is likely to do. I doubt anyone here is going to to watch nearly 800 episodes plus movies and specials to just to find what entries are missing (if any). – Logan M Jun 18 '13 at 18:48

User Caciulacdlac on Bulbapedia has compiled a list of Pokemon that appeared before their generation starts airing. I assume the Japan broadcast date is used as the criteria.

The whole answer below is mostly based on the link above, and several other articles on Bulbapedia.

All the dates cited below will be Japan broadcast dates. Episode numbering will follow the numbering used by Bulbapedia.

Generation II

Episode 117, aired on October 14, 1999, marks the start of the The Johto Journeys (season 3), and also the start of generation II. The Pokemon listed below are from generation II, but appeared in the anime before the journey to Johto started.

Generation III

The first episode of Advanced Generation series, aired on November 21, 2002, marks the start of Pokémon: Advanced season (season 6), and also the start of generation III. The Pokemon listed below are from generation III, but appeared in the anime before generation III (to Hoenn) started.

Generation IV

The first episode of Diamond and Pearl series, aired on September 28, 2006, marks the start of Pokemon: Diamond and Pearl season (season 10) and also the start of generation IV. The Pokemon listed below are from generation IV, but appeared in the anime before the journey to Sinnoh started.

Generation V

The first episode of Best Wishes series, aired on September 23, 2010, marks the start of generation V. The Pokemon listed below are from generation V, but appeared in the anime before the journey to Unova started.

Generation VI

The first episode of XY Series, aired on October 17, 2013, marks the start of generation VI. The Pokemon listed below are from generation VI, but appeared in the anime before the journey to Kalos started.

  • Wasn't Marrill's first appearance in the main series during the Orange Islands arc before that short? – IG_42 Jul 16 '19 at 23:09

Snubbull was introduced in 1998 in the Pikachu special, Pikachu's vacation. It was not until the year 2000 that the Generation 2 pokemon were introduced.
