The lock in animation in Brawl Stars is usually the brawler unlock animation or a special reveal animation when you get a new character. Based on the available references, those animations happen when a brawler is obtained or unlocked in-game, not from a manual setting you can freely toggle on and off.

How it works

  • Open a brawler reward, such as a new unlock from Starr Road, a box/reward-style drop, or an event reward.
  • The game plays the unlock animation automatically when the brawler is added to your account.
  • There is no clear evidence in the available sources of a separate “lock in animation” option that players can enable in settings.

If you meant movement lock

Some videos and guides use “lock” to mean Locked Movement Control , which is a settings option for how movement feels in Brawl Stars, not an unlock animation.

Practical answer

If you want the animation people are talking about in clips, the usual way is simply to unlock a brawler normally in-game and let the reveal play out. If you meant a specific clip or a setting, the term is probably being used differently.

TL;DR

There does not appear to be a special “lock in animation” setting to turn on; it’s usually an automatic unlock/reveal animation tied to getting a brawler.
