E-121 Phi is a mass-produced combat robot created by Dr. Eggman based on Emerl's design. Powered by Chaos Emerald shards and programmed to capture Emerl while collecting more emerald fragments, these simplistic yet dangerous machines can copy the fighting abilities of Sonic and his friends but lack the emotional growth and sentience that made Emerl special.
