Lots of typing here so artiest credit first.
Drawn by  Storm-Blaze who I know put a lot of time into this^^

Anyway as for a wall of text....a team made out of my favourite pokemon of the 7 generations (yes I know a team is 6 shut up). I'm also gonna summarise why I have that pokemon below....if I can.

Also alicorn Saethwr...its been a while^^

Generation1: Charizard
First time I played Red/Blue I did it on easy mode (started with Squirtle) but after seeing Charizard in the anime my allegiances quickly switched. Whats not to like, its your stereotypical dragon fire/flying type with a tail that acts as its own power meter. And it did become a dragon type with its X mega evolution (mind you i prefer using Mega Charizard Y myself)

Generation 2 : Skarmory
2 new types, two new evveolutions and a need to try the new types out. Having bite become a dark type move made it easy but steal was harder to find. Lucky, Skarmoy is pretty much a flying set of swords for all your steal type needs. Although gen twos steal move pool was....small (like gen ones bug and ghost type move pools) its defence made up for it. Also its dex entry says that its dropped feathers are used as swords (Monster Hunter Cameo....please?)

Generation 3: Milotic
Everyone has a generation they missed. Mine was Pokemon "Holyshit brass instruments are a thing" edition so my knowledge is mainly based on what came after. I know Flygon has a nice fan base but I wan't really fussed on Ground Types at the time this came out. Lucky there was one pokemon that folks seems to dread fighting....Milotic. A pokemon that evolves under set condition from Magikarps cousin to become quite the special defence wall. That said if you want me to have team of 6....Milotic would be the one I'd leave out. I have a pokemon in here that can use water moves just as well. Thats said....look body and coils.......yeeeaaahhhh next.

Generation 4. Luxray
Its not often you find a pokemon from the very start of the game you like so much your take with you right until then end. Pikachu is one I can think of but eeehhhhhhhhh defence. Thankfully Gen 4 gave us the Shinx line, ending in the powerful Luxray. Much better defence and a premise for learning dark type moves easily. This was on 3 of my pokemon game teams (caught in 4 and 5 and bred by a friend and traded to me for 6...who had Night Slash as a breeding move).
Also big cat pokemon still on all fours......how rare^^

Generation 5: Serperior
My second started on this list the rare time I used a grass type starter. This choice is mainly appeal....big snake...many coils....hugs please^^The fact is learns Coil and Gasto Acid naturally as well just adds to its...well...vore fan base. (Yes I said it). But....there is a better hugger on the list......

Generation 6: Goodra
You've seen my gallery...how can the big gooy loving cuddly goo dragon not be here^^ The one time I asked someone ahead of me in the game to catch a Goomy and send it to me just so I could get it early. The pokedex entries just make me love it more (suddenly grabbing you for hugs and being so sad it cries when its training hasn't seen its trainer in a while.....I love this gooy hug dragon^^) Battle wise its learns water moves naturally so this would do Milotics water role and its a special defence TANK...especially with a Sassy nature...which I can power breed....I have a sassy Ditto with an everstone.....just saying^^

Generation 7: Silvally
I saw Type:null in the Sun and Moon teaser trailers.....and wondered what the story was with this pokemon. And when I found out....my poor heart >.<
*SUN AND MOON SPOILERS BELOW*

3 artificial pokemon where created by the Either Foundation to be able to utilise the R.K.S. system that the pokemon Genesect had before, allowing them to be every type at once. The were intended to hunt the Ultra Beast and were know as Beast Killers. Somehow the project worked and they were named Type:Full. However with all of the drives in they became uncontrollable and went berserk. They had all the drives removes and they heads locked inside wooden masks to limit their power....and then they decided to mothball the project and the deemed failures were CRYOGENICALLY FROZEN FOREVER....I says this in the game....frozen forever.

Reading that...i had to get one...and i did, training it and getting it massages to raise its friendship until the mask broke and Silvally would feel Sun on his face again^^ I don't think I've ever felt quite so sorry for a pokemon playing the games before.
I gave mine the psychic drive resulting in the pink colours and making it a psychic type....because ever trainer with a psychic pokemon in the game spams the every living fuck out of psychic. Silvally learns X Scissors naturally so HA!!

Anyway end of the wall of text

TL;DR I LEIK THESE 7 THE MOST.

Let me know your faves...I'm interested^^
