although Char's Counterattack and CG R2 are in a different format, if you take a close look, they are similar in some way as the story progresses. both stories are set during a war as characters Char and Lelouch fight to change the world despite having different roles and they are similar as well. The rivalry between the main characters Amuro and Char and Lelouch and Suzaku are similar.
