Eren

Eren is the only son of the CEO and creator of the Lucky Egg Co., a company known for creating everyday items, clothing, and anything in between. When he was a Togepi, Eren's mother, the CEO, would use him in advertisements for things such as clothing, children's toys, and other goods. She stopped after he became a Togetic, not only due to his not as cute looks, but Eren was uncomfortable being exploited to push products. Because of this, she sort of stopped parenting him, and treated him more like an average employee of the company, rather than her own son. 

Currently, Eren is attending nursing school in order to get his medical license to become a nurse. Although he gets a little squeemish around blood and injuries, he's quite proficient at healing. He and Angel know each other from since they were children, and it's a wildly known fact that Angel likes Eren romantically, although Eren, despite his intelligence, is oblivious to Angel's obvious crush.
