Miss Heed's adrenaline infused rage gave her temporary super strength and was able to overpower Demencia in a choke hold and dunk her face into a punch bowl. Demencia proceeds to kick her in the face and body slams her into a pile of cake.
Honestly if Miss Heed is coming back, I kinda wanna see crazy fight scenes of her (actually fighting), between the Villainous gang, especially where she's crazy enough to take on Demencia 😂.
Villainous Headcanon: Miss Heed Unbearable Personality is like Kitten from Teen Titans
Out of all the cartoon characters, I imagine Miss Heed's personality to be like Kitten from Teen Titans from the "Date With Destiny" episode especially after Chapter 10 of The Risky Heist:
Both Miss Heed and Kitten have a spoilt and unbearable personality, their expressions are somewhat similar see images below), wear pink and have a pink esthetic (I kinda imagine Miss Heed having a pink limo like Kitten) and Miss Heed liking cats having a cat headband while the character's name is Kitten and sometimes pretentiously acts like one.
Her relationship with her father is also something like Kitten and Killer Moth! Mr Kelly. does love her daughter (why wouldn't he help clear her name and get out of rehab if he doesn't) however is an extremely busy with his work making him unable to give much attention to his daughter, causing him to overcompensate by giving her whatever she wants. (Like giving her a credit card without a limit at the age of seven)
This led her to become an extremely selfish, spoilt, and demanding brat, who wants to get everything that she wants without caring how others feel or how much it makes other people suffer to get it.
I kinda imagine her father caving into her unbearable requests as hero and her obsession of getting GoldHeart. (like the clip in the video below.
Miss Heed: If I'm going to be a popular heroine, I NEED a popular hero boyfriend too! AND YOUR GOING TO GET ONE FOR ME!
Mr. Kelly: Now, Cec-Heed, be reasonable! You don't seriously expect me to --
Miss Heed: And I don't want just any popular hero!
Miss Heed: I want the best, most popular, charismatic, coolest, and handsomest hero!
Miss Heed: The one that no other girl can get!
Miss Heed: The one who would drive EVERYONE wild jealously when they see us together!
Miss Heed: I want GOLDHEART!!
(Note: Here are the video sources I got the images and video clip above from (1) (2) (3) (4) (5) I clipped out some highlights as I can't I can't include everything. But you should check it because there're more totally hilarious clips showing Kitten's anger and obnoxious behaviour which I headcanon Miss Heed resembles out of her public persona. 😂)
This is also why he hired an agent at the start for Miss Heed when she wanted to become a hero. So that he can focus even more on his work, have a more bearable medium to deal with his daughter's demanding requests, and is able to deal with his daughter's HORRIBLE TANTRUMS, and personally not deal with the monstrosity his daughter grew up to be as much as possible.
Flug mentions in his journal that she is quick to anger when things don't go her way and for as long as he knows her she wants to be the centre of attention and will do whatever it takes to get it. So I kinda imagine her to be like the scene in the video last 2 clips (above)
If that's the case she must be an utter unbearable NIGHTMARE of a friend and student for Flug and her schoolmates to deal with or just generally everyone around her.
No wonder she needs a perfume to make people like her ( 😂jk/)
This is why I theorised that GoldHeart has been avoiding Heed as much as possible and not interacting with her as much as possible, unless necessary. That's why you don't see him in any of Miss Heed's social media posts despite her crazy obsession. As he does not want to deal with her annoying and unbearable personality, despite the importance of Miss Heed's formula, that she stole from Flug, in his plan to end Villainy. 😂
And probably cringes every time he actually has to interact with her.
Also if he were to ever be forced to go on the date with Heed he would react the same way and have somewhat of the same facial expressions (below) like Robin being forced to go on a date with Kitten, having to deal with her, obsessive, pretentious, annoying and unbearable personality and also (shipper headanon) Flug would be Starfire, the one thst GoldHeart would rather go on a date with.
