A playable hero from Valve Software's Deadlock, a gargoyle who suddenly awoke to sapience and was then adopted into the Arroyo family.
In-game, she wields an automatic firearm called the "Cat Dad's Fancy", and a small set of abilities including a Kudzu Bomb that can hamper enemies, a Stone Form that defends her and results in a damaging shockwave, the Watcher's Covenant to share a number of buffs between her and a proximal ally, and can Air Drop either a bomb or ally to deal damage while in flight.

She typically wears a newsboy cap (from which a single head horn pops out) and pants with suspenders (a topless outfit baring her featureless chest), a septum ring, bracelets with vines sprouting from them, and anklets.

Although canonically female, Ivy's in-game model is particularly androgynous; she wears masculine clothing, and lacks breasts, eyelashes, and typical human facial structure; certain depictions may deserve to be tagged as ambiguous gender, male, or andromorph instead. Refer to "how to tag genders" for detailed information.
