E-121 Phi
From Sonic Retro
In fictional universe of the Sonic the Hedgehog video games, E-121 Phi is one of the E-Series Robots created by Doctor Eggman.
E-121 Phi refers to any one of several clones of Emerl created by Dr. Eggman. The Phis' ability to copy attacks is identical to that of Emerl, but since the ability is only powered by Chaos Emerald shards, as a whole it is weaker than Emerl's.
The original basis of Phi's creation was on Dr. Eggman's misconception that Emerl was broken. However, after Eggman realized his mistake, he sent the Phis to capture Emerl. Emerl eventually destroyed all of the Phis, and collected the emerald shard that the Phis used to power themselves.
