# Pets | Big Mech Energy Idle Wiki

Unlocked by scrapping **DJ Leggs**. Normal wave machines very rarely drop a pocket-sized copy of themselves: a **pet**. It is the same machine, shrunk, in your colors, and it likes you now.

**Drop odds.** A pet's first copy drops at **1 in 1,000** per kill of that machine, and the odds halve for every copy you already own: 1 in 2,000 for the second, 1 in 4,000 for the third, and so on up the line. Meeting a new pet is common enough; maxing one from drops alone is not, by design. Only normal mobs drop pets (bosses never do), the [Arcade district](/wiki/districts/) nudges the rate up, and drops only teach to level 10. The [Training Yard](/wiki/training-yard/) handles every level past that.

- **Levels:** repeat finds level a pet, +1 percent to its bonus per level. Drops teach up to **level 10**; the [Training Yard](/wiki/training-yard/) takes any pet to **level 25**.
- **Deploy up to three.** Deployed pets trot beside your Mech in battle and feed their bonuses into the run.
- **Bonus types:** Damage, Scrap, Components, part drop rate, repair rate. Same-type pets stack additively with each other; the total is a multiplier on the run.
- The **Bonuses** drawer under the battle HP bar tracks live drone and pet buffs.
- **Overlord minis:** defeat any overlord **five times** (re-fights count; that is what they are for) and a gold trophy copy joins the bench with its own themed bonus. Every five further defeats add a level up to 10; past that, minis train in the Yard like any other pet. Eleven to collect, one per overlord.
