Unicron is the only collaboration between American rappers MF DOOM and Trunks. The EP is produced by MF DOOM and features Trunks’ rhyming. The album came into fruition after Trunks was featured in the song “Lockjaw” off of DOOM’s album Take Me to Your Leader, under the alias King Geedorah. “Lockjaw” also appears in Unicron as track 3.
