One thing I liked about Shvaughn's role in Robotica (it was confined to essentially one issue, IIRC) was that it played off that 20th century tension with Brainiac 5 - in Robotocia, they were working together, not at odds with one another.

She wasn't a regular character with DnA, but they also portrayed her in an earlier issue of The Legion, with M'onel when they encountered Kinetix. I thought Shvaughn and M'onel made a good team - not in terms of romance - but they were both more mature than the other legionnaires. (I don't know if Lar was actually older, but he seemed that way.)

Holy Cats of Egypt!
