Despite her character development and badass change at the end of Season 2 and Battle of Mewni, I just felt Moon just gotten more worse as a character as the series progressed. Since her daughter,Star began to mature along with Marco and Tom, Moon had little to no character development and instead, she remained the overbearing and strict queen she usually is since she is unable to change for the better and instead,the writers took her overbearingness to Star and ego to full infinity,along with making her racist towards monsters in Season 3,turning her into a bossy,short-tempered,grudgeful,outright mean, and arrogant tyrant of a queen who still acts strict and controlling towards Star(even getting mad at her a lot more than usual),commiting several unethical acts,and treating Eclipsa unfairly by calling her evil and blaming her for corrupting her arm(due to the dark spell harming her badly when she trusted her). Daron Nefcy managed to make Moon a lot more worse in the final season in which in the near-finale,she helped Mina Loveberry create an army of Solarian warriors,which betrayed her daughter and she did this not out of malice,but as revenge against Eclipsa for making her lost in the realm of magic(which it was her own fault for flying into the realm of magic) and planning to wipe out the entire monster race and exile her family out of Mewni. Moon's character development is not very good in the show at all. She's deserves more better than being a unsupportive,unsympathic character who's meant to be compelling and serious,but acts like a bossy,passive aggressive,stubborn,self-centered,petty,and self-entitled bitch with no redeeming qualities(outside of her backstory and Comet(her mother's death).
It's a shame Star Vs. The Forces of Evil ended on a sour note with the rushed final season,which featured pointless romance drama with Star and Marco being forced into a couple,Star destroying the magic, along with creating mass genocide with no choice,the show ending with many plots left untold(including Mina getting away scot-free),and Star's mother,Moon,being completely destroyed as a character by constanly betraying Star by teaming up with Mina Loveberry to dethrone Eclipsa and exile her family out of Mewni as revenge for making her lost in the Realm of Magic(even through she was the one who flew into the realm of magic and Meteora attaking her led to her forgetting the near-bond she had with Eclipsa)and creating a fanatical war with an army of solarian soldiers,along with lying to everyone and leaving millions of people to die while Mewni is under attack.
I wish if Disney brought back Star Vs. The Forces of Evil with a Season 5 with the magic coming back and Mina being defeated. One of the things I would love to see improve is a redemption arc for Moon that would improve her character and look more into her relationships with Star and Comet.(along with showing more of Moon's past with Comet making her first physical appearance on the show along with the first time we hear her speak).
Also,my idea in one of the episodes of the arc is Moon attempting to regain her memories by going inside her mind and repairing them(Along with finally realizing how much of a horrible person she is and a harsh parent she is to Star by looking at her past actions from the third and fourth seasons,beginning with Battle of Mewni and ending with the betrayal and revenge against Eclipsa.)much like The Owl House episode,"Understanding Willow". Also, Star would call out Moon for her flaws and racism against monsters in a epic rant(since The Reason You Suck Speech is one of my favorite tropes),Angie being assertive and helping Moon in becoming a better parent and person,and looking more into Moon's relationships with Star and River(along with showing more of her past,including her relationship with her mother,Comet and a reason why she grew to become more strict,stubborn,grudgeful,bigoted,hateful,and self-entitled as the years went on after she became queen at a young age when her mother was killed by Toffee).
All of this would've improved Moon for the better and made her a much better character than she was in Seasons 3 and 4. It's a shame they kept Moon a two-dimensional character,I know Alex Hirsch made Grunkle Stan better as a character throughout Gravity Falls,since he went from a sleazy con artist owning a fake tourist trap full of fake oddities to a kind-hearted,protective man,why can't Daron Nefcy do the same thing to Moon when her daughter,Star began to mature,yet Moon still acts like a strict and overbearing jerk who still underestimates Star and still sees her as unruly and disruptive,later becoming a vengeful bitch in the near-finale. Disney deserves to bring back SvtFoE with a fifth season,so I can see Moon improve and finally change for the better to try and be a better person once and for all.
What episode ideas do you think that would improve Moon's character and change her into a better character after Seasons 3-4 managed to destroy her character with the hatred and grudge against Eclipsa,constant bad choices she makes such as leaving Mewni to be taken over by Ludo by choosing Star's safety over saving her kingdom by taking shelter at Buff Frog's,and the betrayal to Star at the end of the series?
