If I had created Wizards vs Aliens, things would be a lot different, for example there would be some new cast, characters, species and elements:

Characters:

• Callum Turner as Prince Aldrin Brightstar - The Prince of the Elves who is the son of King Ulrich and brother of Julia.

• Adrian Rawlins as King Ulrich Brightstar - The King of the Elves who is the father of Julia and Aldrin. He is reluctant to let his daughter date Danny due to him being human as he's worried his death from old age will destroy Julia.

• Ross Noble as Slybo - A Goblin who serves King Ulrich as a butler. Randall Moon has a dislike of him due to some unpleasant business which happened between them during the Neverside Wars.
