The best month of the year has only just begun, but Erin Sanders, a.k.a. science-obsessed Quinn Pensky on Zoey 101, is already gearing up for Halloween. The actress reshared her 2012 costume on Instagram Monday (October 3), and it's nothing short of epic. In fact, all her costumes from the past few years have been masterpieces.

While she hasn't shared her plans for this year's costume, let's take a look back at all her gems that deserve a rousing round of applause.

2015 — Ava from Ex Machina

Last Halloween, Sanders went as the humanoid robot who killed the internet's boyfriend. Seriously, her attention to detail is unreal.

2014 — Amy Dunne from Gone Girl

At first glance, I thought she was wearing Lady Gaga's meat dress from the 2010 VMAs, but nope, she's just doused in fake blood. The back of her isn't bloody, however — she attached Amy's missing persons flyer, giving the impression she is always watching.

2013 — Daenerys Targaryen from Game of Thrones

Sanders jumped on the Khaleesi train, donning a long blonde wig and blue eyes to transform into everyone's favorite GoT badass.

2012 — Lisbeth Salander from The Girl with the Dragon Tattoo

As mentioned above, Sanders was 100-percent committed to being the genius hacker of Stieg Larsson's trilogy.

2011 — Nina Sayers from Black Swan

Natalie Portman, who? Sanders tweeted her costume announcement, after fans guessed her character correctly.

2010 — Hit Girl from Kick-Ass

Sanders told Just Jared Jr. she'd been planning this costume "for the last two-and-a-half months" and wore it to the Megamind L.A. premiere.

2009 — Someone badass from Star Trek

When she tweeted her costume, she asked fans, "Do you guys know what I am? (please say yes...)." There was debate in our office as to who exactly she dressed up as, but Spock and Uhura's love child was the winning vote.
