DJ Uplink is a Legendary Build-a-Bot introduced in the Frontline Fighters DLC update for Plants vs. Zombies: Garden Warfare 2. It is a more powerful version of the Uplink Bot and is available from Rux's Bazaar for 25,000 coins, and can only be purchased from said store (only 10 can be purchased, however). In contrast to its original counterpart, DJ Uplink can fire a more damaging laser, and can also fire it faster than normal.
