Courtesy of Marvel Rivals I've had a bit of a fixation on Loki for the last few weeks, so here're some of the headcanons I've come up for him as a little!
(A lot of these are put through the lens of good!Loki living in avengers tower, but some are snippets of him pre-midgard)
Pt. 1 (You're already here!)
Pt. 2
Pt. 3
Loki, naturally, causes significantly more mischief while regressed. Before anybody in the tower found out, he would shapeshift into a younger version of himself and wander around confusing people, claiming his name was Luka
- In that time, Tony started calling him "mini Loki" without realizing he was actually mini Loki, and the young god had a minor freak out thinking he was caught
- The ruse was up with Thor came by when he had the time to spare to visit his friends on Midgard, and caught Loki being a menace while regressed and greeted him cheerfully. By name
- Loki regressing has just kinda. Been a thing. For a long time now, at least a couple centuries, since he was a late teenager. Most people assume it's just him wanting to cause chaos in a smaller, stealthier body, and only his mother and Thor know he's mentally that age as well
- He's either super cuddly with his mom when regressed, or so embarrassed that she knows anything about it
- He also shapeshifts into animal forms sometimes when regressed, snakes especially because he finds comfort in that form. When really little (like baby ages) he'll often regress to a cat or a kitten and be super cuddly. Nobody realizes it's Loki for a long time because he doesn't regress that young often and it didn't coincide with Thor being around.
- He regresses to a very, very large range of ages. All the way down to baby ages (quite rarely, mostly when he's feeling particularly lonely/sad), and all the way up to mid-late teens. In human years, of course, because he finds it easier to summarize in Midgard years his mindset than attempt to explain how Asgard calculates age to his friends
- Has been repeatedly told not to venture into the employee labs causing mischief, this has not yet and likely will not stop him from doing so.
- Those in the R&D labs like him and find it fun to show him all their projects (sometimes he even provides a new perspective for them, though rarely on purpose), but he explored into legal one time and They Do In Fact Not Like Him
- He doesn't ever go back to legal. He steers clear of those floors even while feeling 100% adult
- He struggles to be entertained while regressed unless particularly young. He doesn't like Midgardian toys, though he has tried to like them, the Legos Peter showed him especially, but just finds them boring
- He spends a lot of his time while regressed in the tower going from room to room looking for people to bug.
- Tony thinks he's a sassy brat, but appreciates having an attentive listener that asks questions to ramble about his work with, and Loki indulges in his enjoyment of Midgardian machinery while regressed to preteen ages
- Clint in particular, as the resident prankster outside of Loki, gets a lot of pranks pulled on him to entertain the kid. For the most part, appearing nearby, saying something ominous, and then disappearing between blinks.
- Kids are usually terrified of Bucky, so when Loki seems chill to just hang out with him and sometimes watch a movie, he's just as chill to do so. At first he briefly wonders "Who's kid is this?" and then decides his memory issues are bad enough that it's entirely possible this is the kid of an Avenger or Avenger associate that he's just forgotten
- Natasha really wants to know who the hell this kid is, and puts it together after Tony calls him mini-Loki in front of her. Though she enjoys entertaining him regardless of whether she knows who she is or not
- She tends to show him lots of weaponry and things that she shouldn't be teaching children. They also have challenges to see who can hit a target with a throwing knife more accurately
