Rhedosaurus

Rhedosaurus is a dinosaurian Titan who appeared in Godzilla: Lord of the Galaxy.

Rhedosaurus was the first Titan ever to attack a city. This creature spent millions years living under ice in the Arctic, but nuclear tests in 1953 destroyed his lair. Few days later Rhedosaurus attacked Iceland. Despite being one of smallest Earth Titans, the Rhedosaurus species are still very dangerous - they're not only aggressive, but also have toxic breath and blood that can spread disease. The first one was killed after it was shot with radioactive isotopes, that was used to neutralize the toxins and prevent the disease from spreading.

Design
Rhedosaurus is taken from the 1953 film, the Beast from 20,000 Fathoms, and enhanced by Dinomania into the animation.

The basic design is the same: quadrupedal theropod, spiked back and head with sharp claws and teeth. While the 1953 Rhedosaurus's color is unknown (possibly green with a black tinge to it), this incarnation possesses a more lighter Green with another layer of light green for its underbelly. Its head is more elongated than the head of the stubby 1953 version.

Origins
Rhedosaurus lived in the arctic for millions of years, only for it to be awakened by Nuclear testing destroying its lair.

History
In 1953, several nuclear tests awoke a Rhedosaurus, which first attacked a lighthouse and proceeded to trash a town. The military responded hours later and they managed to hurt it with an artillery missile, but failed to kill it that day.

The next day, the Icelandic army had set bullets and rockets, tainted with radioactive isotopes to wear this beast down. The plan succeeded and the first one died.

After further study, it was learned that Rhedosaurus had toxic blood and breath, that could've caused an epidemic throughout the country. Radioactive isotopes could neutralize this special toxins and could kill it since it heavily relied on its blood.

Abilities
Most Rhedosaurus's arsenal and weaponry were not shown on screen yet. However, we do have information on what it could do.

Venomous Bite
Rhedosaurus had a toxic bite. It can kill smaller Titans, and can poison and wear down bigger ones.

Toxins
Like the 1953 incarnation, Rhedosaurus has toxins stored within its body. However it has two variations of how it can use it.

Toxic Blood
Rhedosaurus, like its 1953 incarnation, has blood that are poisonous and are extremely deadly to humans. It can spread to one person to another if it leaked and can cause a continental pandemic.

Toxic Breath
Another way to release its toxins is through gaseous exhaling. Without having its blood to leak, it can exhale a breath of poison into the air.

Physical Strength
Rhedosaurus possessed great strength. It can manage to knock a lighthouse down with ease and can break a car in half with a single bite.

Amphibiousness
Rhedosaurus particularly lived under the ice for millions of years on the Arctic sea. It can also swim, able to swim from the North Pole to Iceland within hours.

Durability
Rhedosaurus manages to shrug off gunfire and rocket launchers, however heavy artillery can hurt it.

Weaknesses
Radioactive isotopes can neutralize its blood's toxicity, which it thrives on to live.

Heavy artillery fire, like tanks, can hurt it very badly.

Trivia

 * Both the 1953 and LordVerse Rhedosaurus both emerge from the Arctic but have impacted different locations. The 1953 Beast "from 20,000 Fathoms" landed on New York, US and the LordVerse incarnation wrecked havoc on Iceland.
