Used to be a truesona but I'd rather call him more of a fursona at this point.
I renamed him to Guppy since I never liked naming my fursona's after myself for some reason.
He's had many forms over time, because he is a shapeshifter. His shapeshifting is based on his mood, and sometimes even subconsciously over a period of time. That period of time ranging to suddenly or over a span of months, or years in rare scenarios. For example, He used to have antlers. Overtime they turned into antennas and wings formed. However he has a hard time figuring out what emotions are what. He has a tendency to lump emotions into categories like bad emotions and good emotions. He doesn't really notice the shapeshifting until after it happens. (there's more about him but i'll add that later)
