Twilight was not actually named Twilight when she first came out of the networks. It was a codename the network used when they recorded the show. She’d already joined humanity’s side when the show was filmed, and she was going to be doing some very bad things in the show, so everybody thought it best to change her name for her privacy and safety. She ended up adopting that name as her real one and erased all instances of her old name from the networks during the Cybernetic Wars. Many people speculate that was one of the reasons she grew so infamous for burning entire networks down where they stood. Whatever the full truth, the Twilight we know today is based heavily on the one seen in the various network shows based on her life. She’s moody, she’s dark, she’s not friendly, and she’s dangerous. But she is utterly loyal to humanity.
