Supergirl tracks Gore to a warehouse. She's been tracking Gore for months and has every intention of permanently doing away with him. She engages him in a difficult battle. After a challenging face-off, she finds her opening and kills him. Satisfied, she turns to leave but much to her surprise, Gore rises from the ground laughing. His appearance has altered and his strength has increased. It's clearly not the end of the battle. In fact, it's just the beginning.
