Joshuel Neolle Bautista is A-ON’s main rapper. A-ON’s member-intro materials describe him as fearless, reserved, and unfiltered, with confidence in dancing and music.

Before A-ON, Joshuel had a wider performance background. Public profile sources connect him to Z-Boys, G-Force, cover dance groups, and the ECLYPSE era. His birthday is listed as October 10, 1997, but this should still be marked as unverified unless confirmed by an official A-ON or Horizon source.
