E-102gamma is one the more recent creations from Robotnik
and his E-100 series robots. When programmed he recognized
sonic as his sworn enemy, until he captured Amy in Robotnik's egg carrier and Amy appealed to E-102's heart? or something where a heart should be. She convinced him he was doing wrong and he freed her and she stopped sonic, in return, destroying him. So gamma ignored him programming and destroyed the other E-100 robots and freed his family inside and he eventually destroyed himself and freed his flickie-self inside.
