LEGO's most ambitious Pokémon set leaks ahead of release, with a 2,343-piece Poké Ball hiding a world inside

Images of an unannounced LEGO Pokémon set have leaked online via r/Legoleak. They give us a pretty clear look yet at what is shaping up to be one of the most interesting LEGO Pokémon releases to date. The set is catalogued as 72154 and titled "Iconic Trainer Moments: Poké Ball." It shows a large openable Poké Ball that splits apart to reveal a two-level diorama inside — Professor Oak's lab on the upper half and a grassy outdoor scene with Pikachu and Eevee in the lower bowl.

The packaging confirms the "Iconic Trainer Moments Poké Ball" branding and a retail price of $299.99. A final release date has not been confirmed, but the set is currently expected to launch on October 1, 2026. The piece count shown on leaked imagery is 2,343. However, earlier leaks from leaker Max Baut had placed it at 2,339, and the box art in the Reddit post reads 2,386. These are all slight discrepancies that are not unusual ahead of a formal announcement.

The set is also the first LEGO Pokémon release to include human minifigures. Included characters are reportedly Red, Professor Oak, and a Picnicker. Pikachu and Eevee minifigures are also part of the set, but they have both previously surfaced in separate leaks earlier this year.

The set was originally expected to launch on August 1, but was delayed due to production issues reported back in May. All other LEGO Pokémon sets from the same summer wave are understood to have kept their original August 1 date.

Please note that LEGO has not officially announced the set. Given the October 1 target, an official reveal is likely just around the corner. At $300, it would be one of the most expensive Pokémon LEGO sets released to date.
