=== Mega Man ZX Advent ===
Thetis debuted in Mega Man ZX Advent. His backstory is left a mystery, but he loves swimming and has a deep connection to oceans and wildlife. When he was approached by Prometheus and Pandora, he accepted Model L and joined the Game of Destiny to eradicate humanity for its pollution and restore the planet to its natural state.Game manual, Mega Man ZX Advent. 2007., Mega Man ZX Advent. 2007.
Thetis first appears alongside Atlas in the Arctic Ice Floe, where they face Grey/Ashe after hearing about them from Prometheus. Thetis Megamerges with Model L but claims he doesn't want to fight right now, letting Atlas shatter the ice before they depart.
Thetis is next found in the , where he defends the Model W core responsible for flooding the city with ice water. He shows Grey/Ashe the extent of humanity's pollution and challenges them, leading to a boss battle. Upon his defeat, he retreats and takes the Model W core with him. Grey/Ashe then absorbs Thetis' DNA data for A-Trans, which also unlocks a Model A cipher that reveals the roles of Prometheus and Pandora in the Game of Destiny.
After the Pseudoroid boss attack in Ouroboros, Thetis returns alongside the other Mega Men to defend Albert. Vent/ keeps them busy, allowing Grey/Ashe to face Albert alone. Once Grey/Ashe destroys Albert and triggers the collapse of Ouroboros, Model Z immobilizes Thetis via Model L, allowing Vent/Aile to escape with the unconscious Grey/Ashe. Thetis disappears in the collapse with the other Mega Men.
In the bonus Extreme mode ending, Thetis is summoned to serve Master Thomas alongside the other three Mega Men. The significance of this is left a mystery due to the cliffhanger ending of the ZX era.
