This is a tribute to Battle of the Super Sons. Jonathan Kent has powers which should keep on getting more and more powerful as he develops. Mockingbird has already reached the peak of her power which is a bad sign since that means the gap will only continue to grow from this point on. She just isn’t going to be able to keep up with his speed or power so ultimately that puts her in a rough state right from the jump. This fight isn’t a winnable one. Jonathan Kent wins.
