Please note that I used Godzilla Neo as an inspiration, but I look at actual suits as well.

Godzilla is the most powerful (as well as the most feared) of Earth's Kaiju. Godzilla lives beneath the ocean's waves, slumbering until he is called upon to face some fearsome threat. Although he defends the Earth from aliens, mutants, and other external threats, Godzilla has never included "humans" in the list of things he deliberately protects (despite that he later warms up to Masato and his team, and that Minilla, grown up as Godzilla, tolerates the team). To the contrary, it is often human folly that arouses Godzilla's ire. Because of this fact, the Global Defense Force considers Godzilla to be an extremely dangerous potential adversary. Godzilla uses his superheated atomic fire to destroy most threats from a distance, but has proved to be a fearsome hand-to-hand combatant, especially when he can bring his powerful tail into play. Godzilla's most mysterious ability may be his regenerative powers, which always heal his wounds, thus making him virtually indestructible. There have been three Godzillas identified by science so far: Godzilla I was first seen on Oto Island in 1954 and subsequently attacked Tokyo (Later killed by Dr. Serizawa's Oxygen Destroyer). Godzilla II appeared in early 2012, and became the most well known of his kind (he later died in San Francisco of a nuclear meltdown). And Godzilla III was born around Masato's team and may be the least dangerous Gojiran, though he took over as Kaiju King after the death of his surrogate father (he is identified with a scar on his chest inflicted by Destoroyah).
