What is your profile picture?
Currently using Ceroba Ketsukane from Undertale Yellow - specifically a piece from Page 132 of the Artbook. [gamejolt.com]
Prior to that [and still currently on Scrap], I recolored talk sprites of Ceroba from UTY.

Previously was using Noelle Holiday fanart from thunderlet. [deviantart.com]

For any of the Steam UI stuff on my pfp, you can buy the items at the Points Shop.

Your profile doesn't align with that information ... what?
I sometimes change my pfp up for a bit. Unless something changes, it's a "short-term" gag.
Usually.

What are you?
Someone with autism - or silly in the head - or rat brained. Don't dwell on it too long.
If you know me for long enough, you'll learn more about me - rather keep most of that stuff to me.

Payday 2 Main
Duke. He is all I need.

Stop right there.
Kneel before the Duke.
Cuffs on, now.

In Payday: The Heist, my main is Chains (specifically with the Halloween Mask)

TF2 Main
I do whatever I feel like, but I don't think about having a main too hard.

If I were to give a direct answer:
Medic for Casual
Sniper & Engineer for Mann vs Machine

Where did you get "Parodies"
Won in a loadout competition with a Noelle Holiday Medic Set.
(Yes, I go by other names)

What's with the Classified Coif?
On scrap.tf, there are Mega Raffle - where a bunch of people dump items to giveaway. On Mega Raffle #718 [scrap.tf], I won this Cosmetic.
