(A quick note on pronouns: in both dialogue and narration, you'll find Legion refers to himself as both "we" and "I" and is referred to variously as "they," "it," and "he." This is deliberate and intended to reflect where Legion's at in the personal arc I have planned for him. Currently he's starting out juggling his recognition of his own individuality with his connection to the geth as a whole, hence the lack of consistency. The more he embraces his own personhood the likelier it is that he'll shift toward the singular.)

Legion is an oddity even among the geth, having been deployed into the wider galaxy for the express purpose of making contact with people. In particular, the geth consensus took a strong interest in Commander Shepard after the destruction of the "Old Machine" (i.e., Reaper) at the end of ME1. Geth see Reapers as emblematic of what they might one day be capable of becoming; with the intricacy of their code and the complexity of their intelligence, Legion acknowledges that it would be appropriate of the geth to deify Reapers if they were prone to such behaviors to begin with. Nevertheless, Legion has always held fast to the conviction that geth must be allowed the freedom of self-determination. And in a way it's no wonder, because he begins to show signs of his own self-determination as early on as his search for Shepard across the Terminus Systems, when he grafts a piece of Shepard's armor to himself for reasons that he's unable to logically explain.

A first impression of Legion: undeniably alien in appearance, even for a humanoid machine. Tall, imposing, inscrutable, and seemingly unfazed by the gigantic hole in his chassis. Seemingly unfazed by most things, actually, with his distorted monotone and rational approach to interactions with organics. But spend some time, have a deeper conversation, and it starts to become apparent that Legion's cognition is actually very complex. He has a strong interest in philosophical concepts like free will and what it means to be "alive." He is the geth's mouthpiece for their desire to exist and be recognized as a true people, as organic races do. Like most geth, he is intensely curious about organics and their behavior to the point of interacting with them via extranet gaming (and once earned a temp ban for "unsportsmanlike behavior"). He wired a large amount of credits to assist with the recovery efforts on Eden Prime after it was attacked by the geth "heretics," suggesting moral duty. He expresses shame for geth choices, optimism toward geth future, and fierce loyalty to his people above all. He knows he has a soul. In fact, he knows it well enough to want to hear it affirmed by others.

Geth have learned much about organics from observation and occasional intervention but have next to zero firsthand experience socializing with them. As such, Legion is comfortable merely observing others for the sake of absorbing new information but doesn't hesitate to pursue dialogue if he's curious. His inferences about organic behavior, while always earnest, occasionally get delivered in a manner some might interpret as deadpan. But he has never intended to offend, is rarely aggressive, and any acts of violence are carried out deliberately and without anger—a means to an end.

Legion had only just arrived at true self-awareness at the time of his death, which he walked toward gladly for the sake of the geth as a whole. We can expect his time in El Nysa to be fraught with internal struggles and adjustments to his nascent personhood. The small flickers of emotion he's experienced before this—attachment, regret, shame, awe—will no doubt begin to occupy a larger space inside of him, regardless of his previous assertions that they "shouldn't apply." As of the beginning of his life after the Storm, he is simultaneously an extension of the geth consensus and a fully formed individual ego coexisting in one body. Whether this will change, and how, remains to be seen.
