In Pokemon Legends Z-A, side quests provide a welcome diversion from the main plot and allow players to discover new locations, interact with quirky NPCs, and earn useful rewards. A Big Ol' Bunnelby is one such quest that takes you on a brief search for a particularly aggressive Pokemon that is causing trouble in Lumiose City.
It’s a fun mix of exploration and battling an Alpha. This guide will walk you through every side objective, whether your goal is to finish them all or simply earn some simple rewards.

You can begin this quest by going to the Looker Bureau and talking to Emma. She will inform you on a peculiar report involving an oversized, hostile Bunnelby spotted in the vicinity. After agreeing to assist, your next stop will be Wild Zone 3 in Rouge Plaza, where you will meet Trevelle.
You will find Trevelle standing beside a tree, eager to share what he’s witnessed, a massive Bunnelby causing a stir in the area. After your chat, Trevelle will move to Wild Zone 4, near a narrow alleyway where the creature was last spotted. Follow his trail to continue the mission.

Pokemon Legends Z-A side mission: Tracking down and battling the Alpha Bunnelby

Eventually, you will encounter a giant-sized Bunnelby, which immediately triggers a battle. This is not your ordinary Bunnelby. It's an Alpha variant, boasting higher stats with more aggression. Since it’s a Normal-type Pokemon, the best counter is a Fighting-type to exploit its weakness.
Maintain the pressure throughout battle, using strong physical attacks to wear down its health. Once its HP is low enough, you can either throw a Poke Ball to attempt a capture or just defeat it outright to complete the mission. Either approach will be considered a successful result.
