Hasbro is set to unveil an exciting crossover toy collection featuring Transformers and Jem and the Holograms at this year's San Diego Comic-Con (SDCC). The collection includes an exclusive cereal box set featuring Optimus Prime and Jazz, priced at approximately $74.99 USD. This set includes a 5.5-inch Optimus Prime figure that transforms from robot to truck in 14 steps, along with a 3.5-inch Jazz figure that converts from robot to sports car in 8 steps. The packaging is designed to resemble '80s cereal boxes, complete with nostalgic elements such as 'nutrition facts' and tech spec cards. Additionally, a Jem and the Holograms set will retail for around $59.99 USD, featuring a 7-inch Autobot Blaster that transforms into a boom box, along with mini-cassette figures of KP Rosanna, KP Glit, and KP Sundor. Both sets are designed to evoke memories of the '80s, appealing to fans of both franchises. They will be available at the Hasbro booth while supplies last, with limited options also accessible on HasbroPulse.com after the event.
