A powerful electrically-themed Legendary from Generation 8, Regieleki makes for a tough 5-Star Raid boss in , in which assembling a specific type of counters to target its weaknesses is essential.
Added all the way back in April 2023, the Proton Pokémon hadn't made a return to the game since; until now, anyway. Among a bunch of important Pocket Monsters in Max Out Finale event, Regieleki is just one of the tough-to-beat contenders in November 2024's Raid Boss schedule.
With a particularly high Attack stat, you'll be quickly taken out if you go in with the right team. If you head in with a correctly adjusted team, you'll be able to add another strong Legendary to your Pokédex.
As a pure Electric-type Pokémon, Regieleki's only weakness in is Ground-type attacks. This is similar to its vulnerabilities in the mainline games, but super-effective attacks in do 160% damage.
Only having one weakness may sound restrictive for casual players who may not have many Ground-types in their arsenal, but there are plenty of counters evolved from even common Pokémon that make putting a decent team together fairly easy.
