Spoiler That is so weird xD. I think Gen 4 was when they were trying to humanize the pokemon more. Then gen 5 went back to making really outlandish anime types.
And some other Almighty Pokemon from the 4th Gen! Giratina Arceus Yeah! What do u make of pokemon like Reuniclius ;D a thick fat blob of goo! The super sized ice cream cone, Vanilluxe! Then there is Tynamo, looked like a sperm to me ;D ;D 5th gen pokemon looked really funny! But then again there are some great pokemon in 5th gen 2, like Zekrom,Reshiram,Zoroark etc Zoroark and Zekrom are my Favorite in the 5th gen!
or even Garbodor.. It's literally a Trash Heap Pokémon. And another point is their names. It's like they just stopped trying ie Skivvy and Scrafty.
Gen 1 and 2. Some of my favorites are: Mewtwo, Blastoise, Dragonite, Gyarados, Typhlosion, and Lugia.
