OG Ulo is known as a legend in the Quezon City underground battle scene. In 2018, he participated at the Process of Illumination 6 tryouts event and was able to reach second place. The Caloocan-based rapper made his official debut at Won Minutes in 2019, scoring an impressive victory against Crispy Fetus. The crowd admired his unconventional humor and angles as well as his playful delivery. He’s on a hiatus from battling as of now, but hopefully, he’ll make a comeback very soon!
