cererune is a vocalist and pop-industry veteran, notably being incredibly active in his solo career from the ages of 18 to 24. He still does sing and releases records at a slower pace, but he works as a mastering engineer at a record label. He also loves to feature on songs created by up-and-coming music producers.cererune's public persona is cocky, arrogant, and teasing. His friends lovingly call him "annoying". Internally, he does opt to see the good in everyone, having a kind and optimistic nature, but sometimes it gets to the point of being naive and gullible. He also is very quick to stand up and confront people in defense of those he cares about.

background

cererune was created as part of a science experiment, involving splicing DNA of different animals into humans in order to try and unlock the key to immortality. cererune is currently the only publicly known success of this experiment. The laboratory has been abandoned for over a decade, with all related personnel having disappeared entirely. He does not hide his past when questioned, though he does not make it a part of his brand or identity.In the lab, he was given a single name, cererune, which causes frustrations with many websites. This caused him to adopt a full legal name that he does not respond to, which asteroids (the name cererune's fanbase gave themselves) use as a test to spot "posers".He displays animalistic traits due to the DNA splicing in his past, spouting fur on his arms and legs, a tail, and large ears that resemble a chihuahua. He stopped physically aging in his early 20s, and states his age as 27 when asked. He is theoretically immortal and exhibits fast body part regeneration. He is able to shapeshift, and loves to experiment in his abilities. If he shapeshifts for a particularly long period of time, he will be tired and grumpy for a while afterwards, and uses it as an excuse to not go outside for at least 24 hours.
