Emerl (Canon, SEGA)/Earthyboy

Summary
Emerl is a gizoid left behind by the Nocturnus clan over 4,000 years ago due to them being concealed to the Twilight Cage. He was discovered by Professor Gerald Robotnik who attempted to program Emerl to stop his destructive behavior, but failed and had to lock away his destructive and evil personality, aka programming giving him a soul-based off one of his own projects, Shadow the Hedgehog and his daughter Maria that could only be reawakened by certain means, but was later rediscovered by Gerald's grandson, Dr. Ivo Robotnik. Robotnik then threw him away due to not being able to understand how to activate it and left him on the beach. Sonic the Hedgehog, the doctor old nemesis than found Emerl laying there, and decided to train and teach him as a fighter. Once Emerl regained his artificial soul he knew his true purpose and decided to take on the Doctor himself. He ended up winning but lost his individual sentience and captured the destructive energy and linked with Robotnik's new weapon, the Final Egg Blaster, and then ran amok with only Sonic to stop him, he ended up getting destroyed by Sonic in an attempt to put an end to his rampage.

Emerl's most well-known ability is his ability to copy one's movements and reactions and powers to mimick and grow stronger from them.
