I've finished Mallory's revamped design, personality-wise as well. Well, anyway, meet Mallory Winchester! She is part of my Infyrnia AU, and a pretty important character. Here are some stats about her, and yes, I know she looks a lot, and her personality is a lot, like Sans. I actually created her before I even heard of Undertale, and even before it was popular. Just a little disclaimer.

Mallory Winchester is very mischievous and tricksy poltergeist that is one of the first to befriend Infyrnia.
-She loves to play pranks and have a laugh about things, and is pretty chill about life.
-She remains chill even in life-threatening situations, and is amused by the panicking of other people.
-Despite being so chill, she gets flustered and embarrassed easily by affection, and especially love.
-Mallory actually enjoys fancy tea parties, and has a thing for porcelain tea sets.
-She's always listening to music, and always wearing earbuds. She gets real irritable when she hasn't got her earbuds in.
-She may seem a little sadistic at times, and takes death quite lightly, as she can't remember experiencing it. Pain doesn't trouble her either, and battling the player, she doesn't seem to mind letting them die over and over again, though the human has done nothing, or little bad at this point.
-Mallory is actually quite a difficult boss. She doesn't ordinarily fight anyone, but those who mess with her friends really get it. The player normally befriends her before she kills them.

Sorry about the incredibly long thingy about her. I bet nobody reads that lol. I'm still piecing together the story, and I'm designing the main protagonist, or the player. His name may be Elijah, but that's all I know for now. So far he gets stuck in Infyrnia, gets found by Sudoku, blah blah blah, before then meeting Emerald (who's still getting designed), who agrees to be their guide and takes them to Mallory. Mallory needs to kill the player to be socially accepted, as ghosts aren't really that popular in Infyrnia, and nobody likes humans lol. Mallory kicks their butt a bit, then becomes friends with them. Yeah, that's about it. Lol.

PS: Now something about the actual drawing. I'm quite proud of it, actually. The watermark really ruins it, but ehh. Mallory is really pretty in this one! I like this one a lot, and I think I finally mastered drawing noses and shading in ballpoint pen. Probably not, lol. At least I'm one of the best ballpoint pen artists on wattpad now :P You guys should give it a try. And yes, I did sketch this one a tiny bit with pencil, but it's just the head and eyes. Anyways, I'll draw her a bit more, and the other characters as well. See ya guys, and sorry again for the long rant about random crap that probably nobody gives an absolute damn about.
