Grand Maximus

Robot mode
Grand Maximus is a repainted version of Fortress Maximus that was exclusive to Japan.
Grand Max comes with a Mastersword just like the Japanese version of Fortress Maximus, but the sword has been re-coloured to match Grand Max's paint scheme.
Cerebros and Grommet also got repainted but a new addition was the Pretender shell for Cerebros.
