Pneuma

Pneuma a character in Xenoblade Chronicles 2. She is Pyra's and Mythra's true form and one of the three Aegises that make up the Trinity Processor. She is Rex's Blade.

Appearance and personality
Pneuma has an identical body type to Pyra and Mythra, with the main physical differences being long, green hair tied back into a pony tail and green eyes and a green core crystal. Pneuma wears a silver tiara and a white, blue and green plate armor with emerald green crystalline ornamentation. A green energy lattice surrounds Pneuma when she uses Ether attacks. The greek word "Πνευμα" (Pneuma) is written on her chest with the text of Proverbs 4:18 in Latin beneath it: "The path of the righteous is like the morning sun, shining ever brighter till the full light of day". During combat, two wing-like mechanisms hover behind her back. Pneuma's sword is similar in design to the other Aegis blades, with the color being silver and ring near its handle. When activated, the entire sword glows with green ether energy.

Pneuma is depicted as calm and resolute with a stern confidance. This is due to her being the "perfect" version of the Aegis, lacking Pyra's insecurities and Mythra's hostility. While little is known about her thoughts and outlook, she appears to consider herself as one and the same with Pyra and Mythra, who conversely treat each other as seperate entities. She also seems to not prefer being in her form for long periods of time, only being active as long as necessary before quickly reverting.
