The Fusion Crew™ is a collection of cool magnetic figures that you can mix and match to create all-new magnetic figures. Shark Tooth & Gorilla Grip can become Shark Grip and Gorilla Tooth. The more figures you collect, the more combinations you can create! When you're done fusing for fun, you can bring your newly created characters to the Fusion Dome™ for head-to-head competition! Each figure pair comes with five challenge cards you can use to see where your character is the strongest-in Volcano Island, the Ice Cave, the Swamp or the Desert. Then, whoever creates the strongest challenger wins! (Dome sold separately and subject to availability.)
