Zaragas

Zaragas appeared in 1967 TV series called Ultraman. Zaragas (ザラガス Zaragasu) is a kaiju that first appeared in the Ultraman TV series episode 36 "Don't Shoot, Arashi!".

After attacking a children's theme park the day previous, Zaragas appeared in a bright blinding flash and in red smoke that appeared nearby. Zaragas then attacked the city he appeared in only for the Science Patrol to attack him back. Protected by Zaragas's blinding flashes by their helmet visors, The Science Patrol fired on the monster, apparently wounding him. Suddenly, Zaragas sheds some of his armor plates and his power was restored, with his anger growing along with it.

The military then informed the Science Patrol to be called off, informing them that every attack that hits Zaragas causes the monster to adapt and become more stronger and ferocious. However, the Science Patrol was called to rescue some children who were trapped inside of the theme park. Shin Hayata tried to protect the children, but Zaragas discovered and blinded them with his flashes. Unable to watch Zaragas's rampage go on, Arashi of the Science Patrol shot at Zaragas with a new weapon. But like before, Zaragas simply adapted and continued his rampage.

With Hayata now blinded and Arashi now no longer a Science Patrol member, Arashi stole a VTOL jet to attack Zaragas himself, only to be knocked unconscious by Zaragas. Unwilling to listen to his friend die, Hayata transformed into Ultraman, rescuing Arashi before Zaragas could harm him. Once Arashi escaped, Ultraman fought back against Zaragas and had the upper hand at first, until the flashes soon blinded Ultraman, giving Zaragas the advantage. However, thanks to the intervention by Arashi, Ultraman blasted Zaragas with his Specium Ray, killing the monster.

Shelled

 * Adaptation: Whenever Zaragas is shot at by a weapon, he adapts by removing pieces of his shell and replacing them with light bulbs or spikes, as well as improving his own physical strength, and immunity to the weapon he adapted from.

Bulbed

 * Adaptation: Zaragas can continue to adapt to weapons that hit it.
 * Blinding Flashes: Zaragas is capable of emitting blinding flashes of light from the light bulbs on his forehead, back, and chest that are capable of blinding humans and even Ultra.

Spiked

 * Adaptation: Zaragas can continue to adapt to weapons that hit it.
 * Body Spikes: Zaragas can release spikes from his light tubes; five from each pectoral, three from above his forehead, and several dozen from his back.
 * Lightning Spikes: Zaragas' spikes can also emit blue lightning surges and bolts.

Weaknesses
When Zaragas is using its adaption ability, it will pause for a period of time, leaving it vulnerable to attacks.
