Character:BlueZ

Backstory
Rena Ross was an overweight teenage girl in the early 2000's. Her extreme obesity, caused by an eating disorder, led to a heart attack that took her life in 2006.

Post-Resurrection
Rena's emulated brain is chemically balanced to prevent her from getting hungry too often and help deal with her emotional issues. As a result, she is currently much healthier than she was in the Old Real. After realizing at HeriCon 12018 that her Body Mass Index of 25.3 is "good enough", in spite of the judgment of her by her peers as "unattractive", she has become a silent advocate for healthy beauty, and will sometimes give a few words of advice to her female peers.

BlueZ is still a biologically immortal human, but she cares a lot about appearing to be more than that. Her outfit evokes Trinity from The Matrix and her SAM is meant to look equally unassuming until she uses it.
