Quo takes after Unlit, they're both pretty greedy but they're not
afraid to sacrifice something for the loved one.
Unlit is the mouse on the left, Quo is the mouse on the right.
These two are older characters of mine, but I have so much love
for them. They bring back quite some comforting memories.

Unlit is the father of Quo but if you put them in the same timeline
Unlit would not really know this nor would Quo know about his father.
Unlit had donated samples of his sperm to another lab at the time he was visiting.
It was to help the production of the first artificial super mouse, the scientists needed
Unlit's samples because his genes matched what they needed in order to start.
Many years later, Quo was developed. However he was awakened too early resulting
in him having unstable powers and not being able to speak at all.

These two have separate stories, but this is enough to explain the picture
and how Quo started out, I got more in depth with Unlit in another picture of him
which is not currently uploaded to this site at the moment.
