“Look out everybody, things are about to get awesome!”
Dan Zando may appear at various places in the Veins of Helios. To spawn him, Vault Hunters need to complete the Don't Get Cocky mission. If a certain number of debris, meteors, and enemy fighters have been destroyed with the turret, some "high score" text will appear in large letters above the turret. This indicates that Dan Zando will spawn.
Dan Zando spawns not only once, but multiple times in different areas across the Veins of Helios. In some areas, multiple Dan Zandos can be encountered at the same time. He counts as a Badass enemy and drops loot accordingly when defeated.
