Thetis

"My name is Thetis, the Ice Mega Man... Chosen One for Model L."

- Thetis

Thetis (テティス) is a character from Mega Man ZX Advent. He is a kind boy that loves swimming and the sea life, but he wants to punish and rid people from the world for dumping their waste into the sea. He is the chosen one for Biometal Model L, the Ice Mega Man. The player battles him at the Highway.

Model L grants Thetis many superhuman abilities, such as swimming at super speed, ice manipulation, and the ability to breathe underwater.

Appearance
Thetis appears as a young boy with short blue hair with a single large strand standing upright. He is characterized by his innocent, vibrant expression. He wears his Mega Man jacket right under his Mega Man-inspired hoodie and though he's sporting a pair of white thigh-high socks, he doesn't appear to be wearing any pants. He also has a red triangle on his forehead, confirming his status as a Reploid. Despite this, however, Grey when confronting Thetis, implied the latter was a human when he calls him out for harming "humans such as [Thetis]."

Personality
He's a kind person who appears to be quite upstanding and has a fondness for the ocean and sea life. However due to human overpopulation having an adverse effect on the seas, Thetis participates in the Game of Destiny in order to gain the power to restore the earth to its pure state. He considers himself and the other Mega Men to be exceptional beings from the rest of humanity, which he expresses no concern for aside of wanting to rid them for the planet's sake.

Mega Man ZX Advent
The player encounters him at the Arctic Ice Floe with Atlas. Instead of fighting the player, he flees leaving them to fight Chronoforce.

The player encounters him again at the Highway where he is attacking citizens to feed Model W. He Megamerges and jumps into the ocean with Grey/Ashe following him. He explains that he is participating in the Game of Destiny to punish humans for polluting the sea. After he is defeated, he retreats and takes the Model W with him. He appears briefly after Grey/Ashe breaks Aeolus's cipher with all the other Mega Men.

He also appears after the defeat of the eight Pseudoroids in Ouroboros with Atlas, Aeolus, and Siarnaq. They are about to attack Grey/Ashe when Vent/Aile arrive and fights them instead, allowing the player to continue. After defeating Albert, Ouroboros starts collapsing. Model Z separates from Vent/Aile in order to keep Thetis and the other Mega Men busy by freezing the Biometals, which in turn freezes the four Mega Men. Their fates are unknown, but if the game is cleared on Expert Mode, all the Mega Men are seen alive and well in their Megamerged forms. It's also implied that the original immortal Reploid Data was inserted into them, as right after Master Thomas asked Master Mikhail what he thinks happened to the data, the four show up.

Attacks
The battlefield is the ocean, reminiscent of Fairy Leviathan's battlefield in the Mega Man Zero series, with Thetis swimming around while attacking.


 * Screw Halberd - Thetis dash-swims around the screen and twirls the halberd around. Sometimes he feints this attack.


 * Slash Halberd - Thetis stops while dash-swimming and fires off a triangular wave of energy not unlike Childre Inarabitta.


 * Freezing Dragon (Only used against Grey) - Charge attack. Thetis fires off a pair of ice dragons that home in on him. Can be countered using a fire attack or the Homing Shot.
 * Ice Sticker (Only used against Ashe) - Charge attack. Thetis manifests a thick, spiky ice formation which he then shatters, releasing seven ice shards. Can be countered using a fire attack or the Homing Shot.


 * Maelstrom - His ultimate attack involves him summoning a machine from underground that shoots out several snowflakes, and then proceeds to create a vacuum that sucks in all nearby, the snowflakes themselves having been dispersed about from the force. They can be destroyed before the vacuum effect occurs using the Homing Lasers.

Etymology

 * Thetis is named after a female sea nymph of Greek mythology, Thetis.
 * Tethys is an ocean/sea from the time of the dinosaurs, in turn named after the Greek Titaness Tethys.

Trivia

 * Thetis and Aeolus are the only antagonistic Mega Men who appear to have noble intentions for seeking out Model W, with Thetis claiming that he is trying to make the world a better place.
