Wahahah! Finally, a thread where I can show my despise of the Pokémon I despise! Well, the fourth generation wouldn't be worth even mentioning (I'm a first and second generation fan, and find a lot of the third and almost the entire fourth series merely a parody of what Pokémon really is).
In the first series I don't mind any Pokémon, except the over-frequently appearing Rattata (simply because it appears over-frequently).
In the second generation:
- Aipom: Nintendo is showing the first signs of losing their grip, by putting a hand on the tail of a stuffed monkey for no apparent reason.
- Unown: These would be a brilliant idea if there were something making them worth collecting. Just looking for them all without having a reason except just to have them all gets boring really quickly.
- Skarmory: I'm happy to see a non-legendary flying Pokémon that is not also normal type, but why did they have to make it so useless and solid? This Pokémon seems exciting at first, but has no function except enduring for a while.
There goes my list
In the third series, the Pokémon are mostly not too bad, but none of them are fascinating or exciting the way the older ones were, merely substitutes. In the fourth series, the neccessity of making new Pokémon shines through, not leaving much of an impression of originality and creativity. It would be easier to mention the few ones I actually like.
