Built-In Cosmetics

Built-in Cosmetics are Cosmetics that can be only be used with a certain Outfit. Although, there are some glitches that contradict this, for example with Go Cat Go, which may have hilarious results.

The first of these was the Built In Emotes, introduced in Season 6. In Chapter 2: Season 4, Built-In Gliders were created as well.

Trivia

 * On the Heartbreaker outfit, there used to be a glitch where it says he has a built-in emote, though when looking through the emotes, he doesn’t appear to have it. This glitch has been fixed.
 * They appear in the locker emotes section of your emote panel in-game.
 * While most Built In-Cosmetics are assigned for one outfit only, Mjolnir is assigned to both Thor and Captain America, due to Captain being worthy of the Mjolnir in the Marvel Comics and Marvel Cinematic Universe equally.
