Knuckles vs. Dr. Eggman Egg Crusher Mech Reviews
Bricksfanz
“Sonic’s fandom expanded far beyond the games. Whilst it’s unlikely we’ll get a set inspired by the meme-worthy wonky Sonic ice cream lolly, it’s fun to see a set inspired by the wider Sonic canon. The Egg Crusher is a great choice, and the way it’s been created with LEGO... More bricks results in another impressive Sonic set. The catapult and multiple stud firing cannon offer fun play features, and the minifigures, although very similar to those in other sets, complement the set nicely.”
BrickEconomy Expert Review
“The Egg Crusher Mech delivers a stable and visually distinctive design with clever part usage, including car bonnets and a disc-shaped cockpit that aligns with its Sonic Prime inspiration. The set includes a detailed mech build with poseable legs, a hoverboard for Knuckles, and a functioning rock-launching catapult. While the included minifigures aren’t new, the set stands out for its creative mech construction and solid execution of animated source material.”
