Lyn is a Sylph girl of above average height with a very muscular build and physique. She has moderately short hair that is often tied at the back, with her right fringe mainly draping over the right side of her face. She has blonde hair, green eyes, a pronounced nose, and pale complexion. Her eyes, although of considerable size and proportion, often have a sullen vibe to its appearance.

A silent girl that follows command without hesitation no matter how cruel, sadistic or inhuman it may be, as long as she receives what she wants. She is very loyal to those that offer this.
Lyn is brutal in her fighting, preferring to use two daggers to slice and gut her opponents, as they are swifter weapons. She also uses a khopesh, an Egyptian sickle-like sword. She is a dangerous fighter and covered in scars from shoulder to shoulder, one for each life she takes.
In terms of strength, skill, stamina, and durability, she stands as one of the greatest fighters portrayed in The Supreme Legion, her abilities above most players. Lyn is also incredibly strong and seems highly resilient to pain, as she is able to unflinchingly receive damage, suffer pain and still manage to fight. Her skills allow her to face some of the most powerful members of KoB and put her as the second strongest member of The Band of the Nine, only surpassed by Thanos.
