Hoenn. Hoenn is my favorite region. The first pokemon game I played was Sapphire.
Torchic: was my first pokemon, the original starter. Also, Blaziken is a very strong pokemon.
Mawile: Is a pokemon that got my attention by the first time I saw it. I like it, I like its new typing. Back then it wasn't very strong, but mega Mawile can hit really hard and has got good defenses and a very good defensive typing. It would be my team's mega.
Flygon: my first dragon. I catched a trapinch because I liked it, but when it evolved I stopped liking it to LOVE it. I love Flygon and I love its line.
Cacturne: While not te best pokemon, I like its design and it has proven to be more useful and versatile that I thought in my Reborn grass monotype. I like it.
Milotic: When I first saw Feebas it looked cute to me, so I wasted a lot of time unsuccessfully searching it. Later in the game I eventually discovered Milotic and that it was its evolved form, wich made me to want it even more. Despite all my efforts and the time I wasted looking for it, I never got to have one. It's kind of my impossible pokemon love.
Altaria: cute and fluffy. I like it, I don't need more.
Tropius: It isn't a very good pokemon, and then it was even worse. Despite this, the first time I saw it, it fascinated me.
Cradilly and Armaldo: the region fossil pokemon. I put them together because I don't want to choose between them never again. I love both of them.
Shuppet: not banette, shuppet. It's my lil' cute ghost type.
Jirachi: Cutest legendary pokemon ever. I love its typing, I love its powers. It makes people dreams come true and it sleeps for thousands of year, they are my pokemon self!
I would like to add some pokemon of other regions (kingdra, heracross, skarmorry, lanturn, corsola...) but I suppose that Hoenn has everything I need.
