Tess was the main protagonist in the Radioactive series. She originates from the planet Mars, and is part of the Martian race, however it is unknown from where on the planet she comes from. Tess is known for her various personalities, which have all become known and recognised in their own right. Some have even disjointed from her, and lead their own separate lives.

She was rebooted on her birthday, September 01, through the complete release of Tessellate, focusing on the relationship between her and her genetically-created daughter, Tiffany. A novel is currently being planned focusing on Tess, however it is in very early stages.


Tess originates from the non-fictional planet named Mars, which is the fourth planet from the sun in the solar system. Moments after her birth, Mars begins to plummet time after time and ultimately loses its resources, which leads to the planet being forced to evacuate. The Martians quickly rush to find escape pods which will transport them to the nearest and most secure planet, however when Tess' family finally reach one, there is only space for one of them to leave, forcing them to choose Tess' safety over theirs. 

Tess is placed in the escape pod and manages to escape Mars, just as several explosions from atomic bombs are detonated back on Mars. She rides through space and ages heavily due to the Radiation caused by the bombings, and she suddenly crash lands in a strange environment, coincidentally destroying a diamond dome whilst doing so. She creates a crevice in the dome which allows the remaining fighters in the tournament to escape, creating a huge uproar among the viewers and regulators behind the tournament, also angering the puppet-master.


Tess' personality is split in various different ways. She has a lot of alternate personalities which all have unique characteristics and traits which makes them differ from her standard self. It is also known that some of her personalities have grown away from her, and become their own individual being, living their own lives. Significant personalities may have their own articles in the future depending on the amount of content available.

You can view information on all her personalities on Tess/Personalities




Here is a list of Tess' appearances in projects.


Dimensional Destruction




Tess' relationship with Vermilion is very complex. It seems as though the two get along, even being sworn enemies of each other, this is most likely due to the connection they have together, as Vermilion is one of Tess' personas. 





Tess was the first character ever to have a Pacificard made for them. The card comes with the deluxe edition of Radioactive Remastered, however its role is undetermined at this time.


Tess has been very positively received by the community, often being used in various fan works across the community and she was voted as the runner-up to the best Fantendo character of 2015.
