Mythra

Mythra is the Aegis, a Legendary Blade who can grant tremendous fire-elemental power to her Driver, Rex. Pyra and Rex embark on a journey to search for Elysium, and Rex is devoted to protecting her. Due to sharing her life force with Rex, Pyra is not able to recover from injuries like other Blades, and is as vulnerable to damage as any other human. If either of the two were to die, the other would follow. Mythra is confident in herself, reckless, and independent. She has a short temper, a rude disposition, and is not afraid to openly express her thoughts. While during the events of Torna ~ The Golden Country, Mythra is shown to have little sympathy for others, in Xenoblade Chronicles 2 she is much more calm and analytical. Due to the destruction she once caused, Mythra considers herself to be a danger to others, and wants to reach Elysium alongside Pyra to beg the Architect for their death. Unlike Pyra, Mythra is not good at cooking, despite enjoying doing so. It angers her when people dislike the food she prepares. She is also a terrible sleeper, often sleepwalking and snoring among other things.
