Chukwa

Chukwa is the name of a Neptunian sea turtle that has been carrying Gamera Island on her shell for more than 800 years.

Appearance
Just like every Neptunian, Chukwa is a sea turtle of gigantic proportions, being about the size of a small island such as Little Garden. Comparatively to the rest of her body, her head is quite small, possessing a sharp-toothed maw and tiny eyes. Chukwa's carapace is quite spiky, with numerous peaks and steep rock formations protruding from her skull, making the area rather mountainous.

Personality
Little is known about Chukwa's personality, but she seems to be faithful and subservient to the Chukwa Clan. She also seems to be honourable, as she accepted to pay back a debt she had with Princess Poseidon.

Abilities and Powers
A long time ago, Chukwa gained infamy for leaving only death and destruction in her wake. Due to her sheer size, Chukwa is effortlessly capable of sinking ships and fleets. However, her destructive abilities are sealed and controlled by the Scale of Poseidon, a relic that gives one the power to control Neptunians.

Past
Over 900 years ago, Chukwa was born in the Calm Belt. Over the time, she quickly gained infamy as a terrible sea monster spreading massive destruction. Then, at some point in the past, the Neptunian met Princess Poseidon and became indebted to her. Later, when the ancestors of the Chukwa Clan resolved to leave Fish-man Island, Princess Poseidon used one of her scales to summon Chukwa back to her. After ordering the sea turtle to shelter and protect the Chukwas, she gave the latter one of her scales, to let them control the beast. For the next centuries, Chukwa dutifully protected them, drifting around the world and seemingly disappearing from history.
