A skilled one LEGO fan manages to build a custom MOC (My Own Creation) Caterpie from Pokémon series completely from scratch, with no specific set used, and it looks better than most of the newly released and leaked LEGOs Pokémon set. The collaboration between LEGO and Pokémon It certainly didn't go unnoticed, as the first sets released on Pokemon Day immediately sold out on pre-order, and some even tried to sell them for much more on third-party sites. There will be more LEGO Pokémon sets are coming this year, with several Smart Play sets included.
As much as the collaboration has proven to be successful, LEGO Pokémon sets for 2026 may not be for everyone due to the many Smart Play sets shown in leaks, with Smart Bricks increasing the price of any set they're in, and the fact that some of the Pokemon don't look very good. Some fans were very unhappy with the Pikachu and Poke Ball set at launch, saying the series mascot didn't look right, and some of the upcoming sets this summer may suffer from the same problem. Enter fan-made builds, which aren't limited by piece count or smart bricks, and fans have some compelling stuff to put together.

LEGO Pokemon Caterpie MOC Build
Reddit user and YouTube content creator hachiroku24 shared a post on the LEGO subreddit to share a custom LEGO Pokémon built for Caterpie, which seems to be on the smaller end, but still has incredible detail both on the Pokemon itself and the base used for it. The MOC build shows a cute, wide-eyed Caterpie on what appear to be tree roots, surrounded by flowers and grass.

This isn't a first for hachiroku24, who has a YouTube channel filled with incredible MOC builds and has shared several of them on Reddit over time. Among them is a Magnemite, the same size as the official LEGO Pokémon Eevee set, and even a build of the Hornet in Hollow Knight: Silk Song. This Caterpie is particularly well-made, and not only is it a faithful recreation of the iconic Gen 1 Bug-type Pokémon, but it's also proof that LEGO Pokémon sets may be more polished and less blocky than what has been shown thus far.
The Pokemon in hachiroku24's build looks up, and it's reminiscent of the old anime scene where Ash's Caterpie and Pikachu look at the moon, with the former tearing up and dreaming of flying one day. Eventually it does so by evolving, and it and Ash part with a tearful goodbye after Butterfree falls in love and wants to be free to live with her partner. The Pokémon the anime finally reunited Ash and Butterfree 25 years later, creating an equally emotional scene.

Unfortunately, despite many fans of hachiroku24's work requesting instructions on Rebrickable to recreate the build, they have not been shared by the expert builder. In fact, hachiroku24 stated in a reply that they are currently focusing on finishing up studies for a degree in physics, which means they are taking a couple of years off from LEGO related content and YouTube. This may sting for those who really wanted to remake this beautiful Caterpie, but hopefully an original set for this Pokemon will be released in the near future. The many LEGOs Pokémon leaks for 2026 don't include one yet, but both Caterpie and Butterfree are unlikely to be ignored in the long run.
