Deimos is one of the main fighters in Madness Combat, the long running Flash animation series created by Krinkels that began on Newgrounds in 2002. He returns alongside Hank and Sanford in Madness Project Nexus, the arena and story game released in 2021. His grunts and hesitant vocal sounds were clipped by fans into short soundboard clips and shared across gaming and meme edits. This uhhh uhmm moment stuck because Deimos is usually confident and reckless, so hearing him hesitate makes the clip perfect for confusion jokes.
