Even as a Gundam fan, I wouldn't list many, if any at all, as great Transformers, considering most of them are either "lie flat and put a shield over the head", "fold in half", or "split apart".Hey I stayed in the TF family I could of included Macross, Transforming Gundams, Zords, general transforming mecha and your mom
Maybe Nether Gundam. Gotta love the windmill.
