# Overlords | Big Mech Energy Idle Wiki

The uprising has leadership: eleven **AI Overlords**, each hoarding the schematics for your next Mech. The Overlords tab shows everything you have beaten and exactly one active challenge; the rest stay encrypted until the ladder reaches them.

- **Duels are on your schedule.** Waves keep their pace; challenge the overlord when you choose. The arena swaps to a single giant boss and it is a fight to the death.
- **Recommended numbers are advice, not gates.** Each dossier lists a recommended wave and DPS. Walk in early if you enjoy drama.
- **Win:** the Ascension it gates is authorized, a first-kill bounty of Scrap and Components pays out, and some overlords surrender whole systems (the Exo-Frame CEO carries the drone bay; DJ Leggs holds Pets).
- **Lose:** the normal reboot countdown, one wave back. The overlord stays available.
- **Re-fights** pay no bounty, but every kill counts toward that overlord's **mini**: five defeats earn a trophy pet, five more per level (see Pets).

In game, dossiers decrypt one at a time. The wiki has no such patience: spoilers follow.
