Vector

Vector somehow ended up in Gru's Lab and appears as a boss there. The player is tasked by Gru to defeat him. After Vector appears, the player's Minion must dodge his big drones, and tap on the smaller drones to hurl them back at him. After hurling a couple of them back at him, or simply dodging these objects, Vector will be defeated. In the original game design, Vector will still show up seldomly while running in Gru's Lab, much like with any other bosses in the game. After the July 2014 updates, Vector only appears in some levels.
