Radioactive
"Born a Martian, Tess was always curious about what the world had to offer her. She was always interested from a young age in science and astronomy, which lead to her becoming the first Martian to leave their home planet of Mars to travel though intergalactic means. Her vehicle crash landed on one the domes in the Radioactive arena, and she was trapped in the tournament with no means of escape." -- In-Game Description

Vermilion Ashes
Tess appears in Vermilion Ashes as a commanding sargent. She is not shown physically, but only through a video which is used to train the rookies in the organisation. However later on in the fanfiction, it is discovered by Vermilion that a bomb exploded at the end of the video but that footage was erased from the provisional copy, therefore making her status unknown.
