The Verdict
The LEGO Sonic Cyclone vs. Metal Sonic set is the showdown fans have been waiting for — but it’s not without a few loose screws.
When LEGO first announced the Sonic theme back in 2022, nobody expected it to become one of the brand’s most consistent performers. But here we are, four years later, and the Cyclone vs. Metal Sonic set (615 pieces, retailing around $60) is proof that the blue blur’s brick-built adventures still have plenty of gas in the tank.
This set recreates the iconic boss battle from Sonic CD — Amy Rose’s Cyclone mech facing off against the cold, calculating Metal Sonic. For fans of the franchise, it’s a nostalgia bomb. For kids, it’s a toy that actually does something. Let’s break down what you’re getting.
What’s in the box
You get the Cyclone mech, which stands roughly 8 inches tall when fully assembled. The build includes a cockpit that opens for a minifigure, two spinning blade arms, and a flick-fire rotor that launches forward when you push a lever on the back. There’s also a small buildable arena section with a few obstacles — nothing elaborate, but enough to stage the showdown. The minifigure lineup includes Amy Rose in her classic outfit and the aforementioned Metal Sonic, who sports a metallic silver torso and a dead-eyed expression that captures the character perfectly.
Build experience and performance
The build takes an experienced adult builder about 45 minutes to an hour. For kids in the 8-12 range, expect closer to two hours with help. The technic-style connections on the blade arms are clever — they use a ratcheting mechanism that holds position when you pose them, but still allow for a satisfying spin when you flick them.
The star feature is the flick-fire rotor. Push the lever on the Cyclone’s back, and the entire rotor assembly launches forward with surprising force. It’s genuinely fun to fire, and it hits hard enough to knock over a minifigure from three feet away. My test units held up to repeated firing without any mechanical failures.
What buyers consistently praise
The 4.9-star rating across 245 reviews isn’t inflated. Parents consistently highlight two things: the play value and the Metal Sonic figure. One reviewer wrote, “My 7-year-old has built this three times already. The spinning blades are his favorite part — he keeps trying to make Metal Sonic dodge them.” Another noted, “The Metal Sonic minifigure alone is worth the price. It looks incredible on the shelf.”
The dual-piece count is also a selling point. At 615 pieces, it’s substantial enough to feel like a real build, but not so complex that younger kids lose interest halfway through.
Where it falls short
The Cyclone’s wings are the weak point. They attach via single-stud connections, and during aggressive play — which is exactly what this set invites — they pop off. It’s not a dealbreaker, but it will interrupt play sessions. I’d recommend a dab of clear nail polish on the studs if your kid is particularly rough on their toys.
The absence of a Sonic minifigure is a curious omission. For a set literally named “Cyclone vs. Metal Sonic,” you’d expect the blue hedgehog to make an appearance. You’ll need to buy the separate Sonic character pack or another set to complete the roster. That’s a deliberate choice to drive cross-set purchases, and it feels slightly cynical.
Who should buy this
- Sonic fans aged 8-14: This is the definitive Metal Sonic set. The minifigure is exclusive to this set (as of this writing), and the play features are genuinely engaging.
- LEGO collectors: The build quality and display value are solid. Metal Sonic and Amy Rose look great on a shelf.
- Parents of kids who love vehicles and mechs: The Cyclone is a satisfying build with real interactive features, not just a static display piece.
Skip it if: You’re strictly a minifigure collector who doesn’t care about the build, or you’re looking for a set that includes Sonic himself.
FAQ
Q: Is the Cyclone compatible with other LEGO Sonic sets? A: Yes — the build uses standard LEGO connections. The character packs and other Sonic sets can all interact with this one. The Cyclone’s cockpit also fits any standard LEGO minifigure.
Q: How tall is the finished model? A: The Cyclone measures about 8 inches tall, 6 inches wide with the blades extended. It’s a substantial display piece that won’t get lost on a shelf.
Q: Is this set appropriate for younger kids? A: LEGO recommends 8+. The small pieces and the precision required for the blade mechanism make it frustrating for younger builders. If your kid is 6-7, expect to do most of the building yourself.
The Verdict
Buy it if: You want the definitive Metal Sonic minifigure, a genuinely fun interactive build, or a set that’ll keep a Sonic-obsessed kid engaged for hours.
Skip it if: You’re on a tight budget (the $60 price point is steep for the piece count), or you’re hoping for a set that includes Sonic himself.
Rating: 4.6/5 — The fragile wings and missing Sonic cost it a perfect score, but this is the best Sonic-themed set LEGO has released to date. The play value and the Metal Sonic figure make it worth the investment.
