My sonas are all heavily based on me IRL and change appearance depending on the necklace that is attached to my neck.
The purest form of myself is when I wear the Blockchain as it is a direct reflection of me IRL since the block suppresses the external influence by the environment, allows me to fully be myself and prevents me from being cursed by foreign objects such as other pendants.
The Onichain causes me to transform into an evil demon form of myself.
Feely is my traditional/anthro fursona and is brought to life through a cursed Cowbell.
There is no unchained version of "Feels" since it would be equal to raw, uncontrolled emotions and would be fatal for the entire universe...
