>>10288711You can take note of the design credits on the back of the box with BBs and MBs, with the exceptions being those credited to Saiboku22 aka Team X2R. Like the name implies, it's 52toys' in-house design team led by X2R. While most of their BB entries are designed by X2R himself, there are still multiple designers in the team with different styles. Even X2R's own designs made the transition between the cute googly-eyed aesthetic to the more zoids-like one (i.e. Delta vs Sigma).
