Evil Cookie

The Evil Cookies are objects that appear in the Sonic Boom television series. They are deceptively baked treats crated by Dr. Eggman, which, when infused with the genetic material from a person, will turn the consumer into a clone of said person.

Description
The Evil Cookies can only be made through a specially designed machine created by Dr. Eggman. By providing this machine with genetic material such as hair, it can create Evil Cookies infused with that DNA. In some cases, the Evil Cookies' appearance reflects the used genetic material.

When eating an Evil Cookie, the consumer is turned into a "clone" of the one whose DNA is infusing the cookie, giving the consumer that person's personality traits, special abilities and skills, and as well some of the same physical characteristics. However, they not completely override the consumers' personality; Amy retained her bossiness, Sticks her paranoia, and Knuckles' dimwittedness considerably decreased the intellect he got from Eggman. The only way to reverse an Evil Cookie's effect is to feed the consumer with another Evil Cookie infused with her/hers original DNA.

History
The Evil Cookies were created by Dr. Eggman in his lair as his arguably greatest creation yet. Infusing them with his own DNA, Eggman planned to feed them to Sonic and snuck a batch of them to his shack, but they were instead eaten by the other members of Team Sonic. This turned Tails, Knuckles, Amy and Sticks evil and they joined Eggman to plan Sonic's annihilation. However, Eggman's allies turned on themselves when they cornered Sonic, resulting in an all-out fight. To stand a chance, Sonic made an Evil Cookie with his DNA and fed it to Eggman, giving him his speed, moves and heroism. Together, they held the others off and produced new Evil Cookies made from Team Sonic's original DNA which turned the team back to normal. Not liking the idea of a good Eggma either, Team Sonic restored the doctor to normal too with his own Evil Cookie.
