Took a Level in Badass: One of the most literal examples, since there's an actual Badass stat you can level up.

Star-Crossed Lovers: With Q-Pernikiss, and potentially all the other girls as well, if you choose to sacrifice yourself during the ending.

Shorter Means Smarter: If you level up your wisdom or intelligence stats a lot, considering Ayano explicitly describes Marshmallow as being 4'2'.

Heck, one bit of dialogue has Bonnibel ask Marshmallow if they changed their gender.

Purely Aesthetic Gender: Just pressing the Gender Bender buttons in the stats menu at any time results in an Easy Sex Change.

The Power of Love: If you perform a Heroic Sacrifice, the portal closes because it was an Act of True Love.

Heroic Sacrifice: Has the chance to do this during the ending.

Harem Seeker: Presumably, since girls just keep falling in love, though this may also be due to Q-Piddy's influence.

Gonk: At low stat levels, Marshmallow has a hilariously hideous appearance.

Ayano points out a few features from her 'research', though (specifically, that they're 4'2', weigh 102 lbs, and have a birthmark on their right heel). You can't get more featureless than a White Blob.

Empowered Badass Normal: Eventually, one of their jobs is being a wizard.

Did You Just Romance Cthulhu?: Two of their haremettes are a Sealed Evil in a Can and a Humanoid Abomination.

Did You Just Punch Out Cthulhu?: Eva's introduction involves punching an alien mech in the face.The Chosen One: The Sexy Chosen One, at that, according to Karma and Sutra.Somewhat downplayed because they have been referred to as Marshmallow a scant few times in-game (like Alpha's ode to them being called 'A Song About Marshmallow').

Canon Name: While they're meant to be an Audience Surrogate, and most characters refer to them in ways other than their name, Word of God has stated that their canonical name is Marshmallow.Breast Expansion: While a male Marshmallow becomes visibly sleeker and buff as his stats increase, a female Marshmallow bust visibly grows and gets perkier.Fumi notes that they are 'generously endowed', and seems rather enthusiastic that they are. Bigger Is Better in Bed: For the male Marshmallow, and Buxom Is Better for the female Marshmallow.Marshmallow somehow hacks Ruri's closed-circuit camera that wasn't even connected to the internet.

Nina: Why do you have so many jobs? HOW do you have so many jobs?
