Promotional sets are a subtheme of Sonic the Hedgehog that consists of 3 sets that ran from 2023 to 2025. Most sets were released in 2025 which accounted for 2 sets. As of today, the average annual growth of sets in Sonic the Hedgehog Promotional is approximately 16.6% but this should level out to around 11.6% in the coming years. This change in annual growth is primarily due to the initial retirement of these sets.
The LEGO Sonic the Hedgehog theme was released in 2023 based on SEGA’s classic videogame series, Sonic the Hedgehog (the first Sonic the Hedgehog set arrived in 2021: a recreation of the game’s iconic Green Hill Zone level). The Sonic sets are geared towards play, with one including a launcher that sends the hedgehog racing through a full inverted loop, as well as introducing minifigure versions of other characters in the Sonic universe.
