Following the end of the Power of the Primes Trilogy and the unification of Hasbro and Takara product, the War for Cybertron Trilogy was the beginning of a new era. This trilogy was split into three acts: Siege, Earthrise, and Kingdom. Each act also received a cartoon series on Netflix.  The Siege line featured alien alternate modes, micromasters, and battle masters. Following this, the Earthrise line featured primarily real-world-adjacent vehicle modes, micromasters, and battle masters. Afterwards, the Kingdom line introduced many Beast Wars characters and 1986 movie characters to celebrate their 25th and 35th anniversaries, respectively. Kingdom featured realistic animal and vehicle alternate modes and the core size class– a successor to the legends size class.
