Character Ideas (wiki contributors notes)
I'd like Star to have the same upbeat personality and passion for battling but for her to grow increasingly hateful of ludo and upset towards the devastation and how in the new timeline she is believed to have been killed by Ludo before she could get the wand.

I re-imagined Marco to be alot darker in the altered timeline and have his new persona be inspired by Hercules in the third God of War game. In this timeline Marco has become the general of Mewni's royal army and has become incredibly pessimistic towards everything and has become self loathing and blames himself for Stars "death" in the new timeline. Marco initially believed that Star was a monster spy or a clone abomination of Star created by Ludo to weaken him. After a lengthy battle with Star with him using an enchanted cestus (which greatly enhances his strength) created the royal blacksmith and Star using a wand against him. He reluctantly enlists her in the royal army but during the movie he soon realises who Star really is and admits some secrets to her and becomes her most powerful ally.

In the new timeline Ludo has gone completely insane due to his excessive use of the wand and has horrifically mutated himself to become the most powerful being on Mewni. His abusive traits towards the monsters has become so bad that they consider failing Ludo as a fate worse than death. Ludos secret as to how he change the timeline is known only by him and him alone and will take that secret to his grave.
