Do u have any hcs for marvin in general? :3€
WARNING! EXCESSIVE YAPPING AHEAD!!!!!!
Well, you've been warned buster!
Oh yes. I know exactly where to start.
Well, if memory serves me correctly, Marvin is a frequent multiverse traveller as per to the lore regarding the comic where he meets the Martian Manhunter. If you are unfamiliar with that crossover, I reccomend that you read it if you are an avid Marvin fan as I am. It is a peak reading experience if you are a big fan of Marv and/or the Martian Manhunter. Anyways, back on subject here, but as a multiverse traveller, he has seen almost basically everything there is to offer given that he is speculated to be immmortal. However, since he has seen everything, it doesn't mean he can PREDICT everything.
The reason why he comes off as a brat is because he normally never has to try in regards to getting anything he wants simply because he can go to any dimension he wants and because of how technologically advanced he is. With everything and anything readily available to him, he can't grasp as to why other creatures can't do the same things he can. Specifically Earth people. He finds it rude as to how the Earth is progressing without a single soul regarding his existence on Mars. Well, the way I see it in Marvin's perspective is if you imagine having someone you really want to talk to and they seem far too busy to acknowledge your existence and any effort made to talk to them is just not coming through. Annoying right? I feel like that is the way Marvin feels with every attempt to talk to the people on the Earth. With that frustration only fueling his anger, it would leave Marvin to do the drastic move of destroying the Earth entirely.
As per the Martian Manhunter comic, he is only focused on destroying the Manhunter's Earth than listening to him. Another key point I'd love to address is that Marvin is definitely mischaracterized in the later Looney Toons adaptations as just a villainous character. How I can prove this is by how he finds the Earth life facinating in the episode 'Mad as a Mars Hare' by how he is documenting the life with a telescope. In his first appearance, he never really had an explained motive as to why he was going to blow up the Earth. I highly doubt that he was going to blow up the Earth because it was obstructing his view of Venus/Mercury. With that being said, it only makes me wonder as to why they went on with this mischaracterization of him with all of the evidence I have gathered here to support this headcanon.
I also think that he prefers the dimension that we see him in rather than any other dimension. Why I believe this is because he prefers to be alone most of the time, but not all of the time if that makes sense. The reason we see K-9 every so often is because Marvin can choose to have his company or not either by vaporizing him and obviously having the option to clone him. And I am a firm believer that every time we see K-9 is a different clone of him. To prove this is because he acts differently in each adaptation sometimes as a soldier or sometimes more dog-like which can be due to how Marvin chooses his companionship. Again proving my point as to how Marvin has everything and anything readily available to him.
Another factor to add to my headcanons is that Marvin genuinely yearns for someone that has been and seen everything that he has that isn't just a clone of himself. Or at least finding someone he can share the things he's seen and done with. It is obvious in some cases that Marvin loves doing what he does, but wants to share his experiences with someone other than K-9 or himself. I am also a firm believer that he conquers other planets just to have the flex that he has taken over so many more planets than the Earth ever could. Marvin definitely wants people to know that he is a more superior being without coming off as rude/overbearing yet he does not want to be undermined for being deemed short or not a threat. Despite that, Marvin would be feared in our dimension since we have seen what he is capable of building and how he can follow through with his threats of blowing up the Earth without Daffy or Bugs stopping him with some cartoony antics.
Marvin definitely has tried Earth cuisine before across the planet at least once. Deeming America's potato salad as his favorite and is one of the reasons as to why he is hesitant on obliterating the Earth. I do believe that he wants to learn more about Earth culture but is worried that he will not be easily accepted amongst them and be overwhelmed by the fact that he cannot take on the entire Earth by himself. This theory could also explain as to why he just observes the Earth with only his telescope.
I also believe that Marvin has a 2x hotter body temperature than humans, explaining why his military status is X-2. I also believe that he had made up the martian army of just clones himself and instant martians which just seem to be Jovians, (Jupiter inhabitants), condensed into round marbles that can be activated with water/any hydrogen based liquid.
I also speculate that the Duck Dodgers show isn't canon in terms of other martian life. Marvin's title remains in the show as normal. He had made up Tyr'annee as someone he prefers in terms of romanticism. General Z-9 is meant to symbolize Marvin and how he wants to be percieved but also shows what he doesn't want to become. The Duck Dodgers show is also based on Marvin's words in regards for how space is actually like. He also let Daffy and Porky have creative freedom in terms of how their characterizations are like in the show just as long as they had shown to be a very formidable enemy against the martian army.
Aaannnnnndddddddddddd that should be it for now. Those are all the headcanons I have regarding the pookie! I'd like to emphasize that he would be a very caring character to be around despite how dangerous he is. He just has a lot of problems trying to show that caring side of him. And the mischaracterization of him within pop culture and Warner Bros. is so insane tbh. But that is just the way I percieved him as a character and I would so give him and K-9 cuddles and affection as they both so deserve it.
