As the guitarist for Lizzy Elm's band and a solo artist himself, Derrick Cunningham has made himself known in multiple ways throughout Robloxia and Romarkia with his playing skill and heavy metal songs.
Before coming to Robloxia:
- He was born in Romarkia in the city of Ro-Hamburg.
- He had issues with his old home being broke into and robbed.
- After his older brother Lucario Cunningham moved to Robloxia to New Blockers City, Derrick decided to do the same to pursue his career.
After coming to Robloxia:
- After he moved to Robloxia, he felt that Lucario Cunningham's plan of forming the Midnight Killers was nice and all but he wanted no part of it.
- He moved to Greenville, Wisconsin where he met his new bandmates Lizzy Elm and Axel Ross.
- After he started touring with them, he gave himself the stage name of Demetris. Robloxia's music news outlets kept messing up the articles about him and Robloxia's churches were calling him Lucifer, so he decided Lucifer would be his stage name and the old one would be his regular nickname.
- He moved to Bloxywood Hills after his band went global.
- He was involved in a lawsuit with Preston and Prestonia due to a post he made on Blox-Twitter mocking the country. Preston dropped the case due to Outerscope Records threatening to sue Prestonia as well as the United Roblox Countries deeming the lawsuit illegal.
- He visited the Furry Parade 2024, where he got to see Director Arctic Fox for the first time.
- He would get shot and killed in 2031 after he was "interviewed" and was forced to play a deadly version of Hide and Seek by the Saviors of Roblox.
