The modern Hulkling - As wrong interpretation became depiction(Part 1)
Hulkling is a crappy character. It's sad given where we started, but it's sadly true.
The problem here is like it often is with fiction as it goes through the hands of multiple creators a misunderstanding of the character likely driven by a lack of caring or carelessness on their part. However another factor is the misunderstanding of the character from the perspective of the fandom, which translated into that interpretation used by creators.
So let's get through a few of these misunderstandings.
The classic Hulkling begun and is widely based around Alan Heinbergs depictions, partially due to his own contributions and partially due to the fact that marvel would actually run books written by other writers past him to make sure it would not derail plans of his for nearly a decade, probably giving writers incentive to pay attention.
Originally his costume was sleeveless black leather, fingerless gloves, boots and piercings with concepts for his design with longer hair, a coat or a single sleeve existing. The whole thing had more similiarities with the outfits of some rockstar than the traditional skintight superhero costumes and gave of a distinctively more "Fuck the establishment" than "All-American" vibe.
This outfit would then change to something less rockstar with a somewhat more casual look due to a zipper in the front and a yellow scarf. At this point his hulkling form would also become more distinct from the just green and muscular Hulk with armored shoulders, a scaly design and claw-like fingers, while he would maintain his natural blonde hair color when transforming.
His true form meanwhile would be shown to be significantly shorter. Noteworthy is that he is shown to be significantly shorter than Tony Stark in his human form, while a flashback in the special issue shows him as Tony to be of the same height as Gregg Norris, whose height Teddy copies in the issue. This suggests Teddy is in fact during the main books in the form only briefly shown in the special issue.
Teddy is shown to be slightly taller and broader than his boyfriend Wiccan with muscles usually drawn as less pronounced and emphasized than the twin brothers.
Regarding his characters portrayal Teddy would be shown to be a comicbook and superhero nerd like the rest of the team.
He would be highly polite with his perfect manners being one of the first things noted about him and him commonly adressing characters as Sir even when disagreeing with them or facing off with them.
He was depicted as particularly mature and considerate, presumably partially meant as a necessity when growing up in a single parent household with a working mom.
He is depicted as the most rational member of the team, to the point he fails to predict more irrational and emotional actions, such as when he doesn't believe Patriot would go out on his own or that Billy would sneak off to Latveria by himself and grow frustrated with these, such as berating Billy for walking out of a discussion with the Avengers and calling both him and Eli idiots, when going into danger on their own.
His thoughtful behavior is also shown to make him one of the more hesistant Young Avengers to act when discussing a plan and extending to the point he would opt to intimidate an enemy into surrender rather than striking him. He is still seen acting immediately when it is the result of an immediate situation, such as striking down an attacking Growing Man, latching onto Ironman giving chase to Iron Lad or casually stopping a purse snatcher by reflexively stretching his arm, but rarely as a commanding voice within the teams discussions.
Even then Hulkling is rarely shown acting entirely without a plan such as immediately assuming the form of Reed Richards to cover-up his powers when stretching in public and diving right in to a fight between two warring alien factions, but with the idea of using their interest in him to negotiate a ceasefire.
The Hulkling presents issue depicts Teddy breaking from rational behavior as he is in emotional distress over the seeming return of his father, which is considered wildly out of character for him in-universe and up to that point only happened once when he saw Billy seize to exist all-together. He then spents his only conversation with what he thinks is his father venting about how unfair the universe treats him allowing himself to be an emotional immature teenager just once, before admitting that he knows his father is actually correct about wanting to leave for his own time and returns to his normal more mature self, as he tells him farewell.
The issue with Hulklings classic depiction is ultimately one thing. It is too complex. The character cannot easily be reduced down to a catchphrase an archetype or some typical behavior. So where characters like the Hulk or Deadpool might receive deep and complex emotional story arcs or be written as one-dimensional murderous psychos, they can always be dumbed down to the anger monster or the smartass mercenary and it's not wrong with Hulkling that is not the case so the fundamental character core is not consistent.
Trying to sum up Classic Hulkling you get something along the line of a rational, emotional, kind, manipulating, honest, regular teenager and alien acting as an archetypical superhero, who wil threaten to maim people on-panel by gouging their eyes out, is emotionally supportive of his teammates, capable of moving two cosmic empires with his actions and takes a background role within his team.
Neither are you capable of gathering all these things just by skimming the books or reading the wikipedia summary of his story. Nor would you be able to come up with a correct general characterization if somebody gave you this. So writing Hulkling properly takes effort. Sure, writing anyone takes effort and its not like Hulklings ultimate complexity within the original YA books was far greater than the rest of the teams, but if you end up writing Kate Bishop as a badass archer and leader with a chip on her shoulder you still get a lot more right then, when writing Hulkling as a rational alien(never done) or an emotional fist fighter.
Future writers would essentially end up reducing the character down to simple tidbits of trivia about him dumbing down the character to nonsense like his heritage as the heir to a galactic empire, perfect boyfriend, kind person or dumb jock(wherever that came from). Strangely missing are shapeshifter and Captain Marvels son. And why bother to put in the effort, as long as you claim this is for the lgbt-community and toss in something showy to claim that, like a threat to their relationship or a couple of panels of them hugging or kissing you will get a positive enough response.
