Do you liek...actually, no, I'm not gonna sink to that level. I could, but I won't. Swampert is one of the best starter Pokemon in any of the games - its got great base stats, a pretty cool design, and it's only weak against one type (albeit, it's suuuuuper weak against that one type). So if you liek Mudkip, you'll loev Swampert GODDAMMIT I'M SORRY
As far as origins go, few Pokemon have ones as weird and awesome as Deoxys': it began as a space virus that got hit by a laser beam, which sounds like something an 8 year old would come up with (keep in mind that 8 year olds have the coolest imaginations). On top of that, Deoxys is one of the first Pokemon to have multiple forms - depending on which cartridge you were playing on, Deoxys would take on a different appearance and different stats, all of which looked like they came from an 8 year old's sketchbook of what a cool new Pokemon would look like. Speaking of - after seeing Pokemon that look like ice cream and swords - are we entirely sure that 8 year olds aren't behind Pokemon?
Beginning its life as Ralts (the Pokemon that kinda looks like male genitalia), it's a little surprising it turns into Gardevoir - who looks a lot like some kind of elegant dancer (and a lot of other things, if you dare to venture into Google Image Search - which reminds us: NEVER GOOGLE IMAGE SEARCH ANY POKEMON EVER BUT ESPECIALLY NOT GARDEVOIR). Apart from its traumatic internet legacy, it's a pretty solid Pokemon (now one of the added Fairy-types), and its Pokedex entries indicate that it would do anything to protect its trainer. Always nice to know your Pokemon has Stockholm's Syndrome.
The giant Water-type Pokemon Kyogre is something special - the mascot for Sapphire, a key figure in Team Aqua's plan to turn the world into that shitty Kevin Costner movie about a world of water (can't remember the title), and the eternal enemy of Groudon. But most importantly, it looks more like Free Willy than almost any other Pokemon, so if you wanna re-live your early 90's teen dramas, Kyogre is the place to start.
