Ferocious Dinobot commander Grimlock joins Takara Tomy's new "Henkei! Henkei! Transformers" lineup! This detailed action figure can transform between his mecha T-Rex mode and robot mode, and is packed with features: chrome parts for his feet and neck in mecha T-Rex mode, his tail turns into a handheld weapon, his spring-loaded gun can fire a projectile, and a clear part at the back of his head allows light to shine through and light up his eyes!

Initially released in the U.S. in Hasbro's "Transformers Classics" toy line, Grimlock and other Transformers in this new "Henkei! Henkei! Transformers" lineup are redecorated by Takara Tomy for the Japanese market with a different color scheme for a more accurate resemblance to their counterparts in the original "Transformers" animated show. Each figure in this series also features chrome-plated parts and comes in Japanese packaging.
