Julie-Su

Julie-Su is a Mobian Echidna and the girlfriend and distant relative of Knuckles the Echidna. Born the daughter of Luger and Mari-Su, Julie-Su was brought up amongst the Dark Legion. After her parents were murdered by her half-sister Lien-Da she was placed in the foster care of Simon and Floren-Ca before she was taken away from them as well. Serving as a support troop in the Dark Legion for years, she eventually left it to join Knuckles and his group, the Chaotix. Since then she has fought along Knuckles' side and continues to function as a key member of the Chaotix.

Julie-Su is very similar to Knuckles in personality, acting tough most of the time while really being quite caring underneath. She is an advocate of "girl power", serving as the only female member of the Chaotix until Saffron and later Rouge joined the group. Julie-Su is always willing to go into any danger, particularly when it involves saving Knuckles, whom she always attempts to aid despite his assurances that he doesn't need it.

Julie-Su, known to her friends as Julie, Jules, or 'Su, prefers to go into battle with her friends rather than wait on the sidelines. She is also even more of a tomboy than Sally, and refuses to be seen in a dress, though she does wear them on special occasions. Despite this, she and Sally do share a number of feelings, including a deep desire not to see the men they care about-namely Knuckles and Sonic-get hurt.

Despite all they've done to her, Julie still cares deeply for her family related by blood.

Like her surrogate parents Simon and Floren-Ca, she also genuinely loves them and considers them as part of her family by calling them father and mother.
