Despite your name I'm going to go with Piloswine. Color coordinated and perfect for the icy wastes in your background.
Sawsbuck, specifically the Autumn one.
I'd say Gothorita, compliments both your fashion sense and the black and white color scheme a good chunk of us are sporting.
Chimecho! I think it would complement the instruments on your HA :P
Where did you get that background!?
I would say either haunter or ghastly. XD old school pokemon all the way.

I'd say you'd have a Kadabra as your partner. Something about your HA and background strike as more psychic than ghost type.
It's from an achievement for the new Gravedigger game - you get it after finding 50 ghosts n_n
And I think Mega Banette would suit you :P
I like that idea actually ! I'm not entirely sure why but your HAs expression reminds me of lickitung.
Oh I'm at like 30 something. All the more reason for me to keep playing ! I love Banette. I have one on my alpha game. Btw I'm nosy and I see that you lend stuff for achievements which I didn't even know was possible. Could I bother you for some lends? I just started even caring about them.

it's the goofy grin, it makes my HA look like he's about two seconds away from sticking out his tongue while trying to one man band. I still say Kadabra would be perfect for you though going with your next pokemon down the line I think it'd be either Hypno or Umbreon.
Ludicolo because of the instruments c:

Hmm, I'd say Bastiodon. Something about the look on your HA's face says " I have a dinosaur in my home. It's terrible for my health but great for my abs."
Illumis or Volbeat because of the lights/fireflies
(And also besides Feraligatr for mine, please lol)
