Megalovania was composed by Toby Fox and first appeared in the EarthBound Halloween Hack before becoming the battle theme for Sans in Undertale in 2015. Its driving rhythm and memorable melody made it one of the most remixed tracks in gaming culture, appearing in countless covers, animations and memes. Phone call versions reframe that intensity as a ringtone, playing on the surprise of hearing a final-boss theme for an everyday notification. That contrast keeps the clip popular with editors who want instant recognition and a quick laugh.
