|Full Name||Bratt's Lair|
|Secret area||Bratt's bedroom|
Bratt's Lair is a location in Despicable Me: Minion Rush. It is the sixteenth location to be featured in the game and was introduced in update 4.7.0. The location is based off of the fortress of Balthazar Bratt in Despicable Me 3.
Bratt's Lair is the first location that was adapted from Despicable Me 3. The location is surrounded by sea, just like Anti-Villain League; the minion will be delivered to the building by an aircraft controlled by other minions, entering it from a small door on the giant Rubik's Cube. The interior of the place is similar to Gru's Lab and Anti-Villain League, and colorful busts of Balthazar Bratt can be seen background at turns of the track.
The running track of the location is deep blue with lighter lattices on it, and there is separation of the three available tracks. Obstacles featured in this location include a speed booster-like track with Bratt's gum on it, which can trap the minion and cause the end of the game, while the punchers aside and rolling obstacles work like those in The Volcano. There's also a slide that resembles a glowing force field that can deliver the minion smoothly and there's no obstacle on it.
There's a secret area of more features. Once the minion enters, Banana Splitter and Banana Vacuum can be picked up to collect bananas, and Bratt's living room, gym room and bedroom can be seen in the way.
- At the screen obstacles, there's a minion behaving identically to that of bathroom obstacles (both are seemingly waiting for the bathroom badly).
