Hasbro planned to center the storyline of Transformers: Legacy around Straxus as the main villain. To this goal, a Leader Class Straxus toy was solicited for the first year of the toyline, and art was produced for his eventual design in the franchise. Anna Malkova created the design featured in the 2019 IDW comics as a stepping stone toward this purpose, along with an "after 'accident'" design closer to the Legacy art and homaging the character's fate in the UK comics of being a head in a jar. When Netflix declined to pick up the planned three-season Legacy series, those plans were dropped—the second design for Straxus never appeared in the comics and the toy was replaced with Transmetal II Megatron.
