Ultra Armor

The skin of an Ultra, it is natural protection against many forms of attack. Any being that calls themselves an Ultraman, has this on them.

Nature
Every Ultra is born wearing a protective layer all over their body. It is aptly named Ultra Armor for that is the function it serves. Each armor protects it owner from harm, being resistant to tear and immune to wear. Almost if not all Ultras are resistant to flames and heat and beams.

Ultras have been shown to be as immune to conventional weaponry as most monsters, shrugging of laser blasts, canons etc. Only powerful aliens and monsters appear to be strong enough to deal them damage. However Ultras are not invincible, any blow they receive will still translate to their bodies as the Ultra armor is still just their skin, also blades and other pointed objects like monster teeth have been shown cutting them and making them bleed. An Ultras biggest weakness, at least those from the Showa Universe, is the cold. Because their homeworld has no winter, Ultras never evolved a way to counter cold weather. It is stated that his weakens them because it impares their ability to absorb sunlight, heavily implying, if not stating outright that the Ultra Armor is how they processed sunlight (which was already assumed by fans).

In some Universes Ultras don't share this weakness, while it is universally accepted that Ultras all have the same resistances, with Tiga, Dyna, Gaia and Agul it is stated that they are resistant to low temperatures. The original Ultraman was immune to electrical attacks, a resistance no other Ultra seemed to share with him.
