Hmmm... the thing is what to turn him into with the whole rule about not making it too much like the comics.

I think that rule is there to make sure we don't have any carbon copies of these well-known characters.  You can look at my and NMS's character sheets to see how you can take inspiration from Marvel and DC comic canon and mold them into their own characters (our characters, along with War-Pulse, are probably the most 'traditional' superheroes in this game at the moment).  

For instance, at first glance, Arachne might seem like a carbon copy of Spider-Man (although I made her prior to Marvel publishing Spider-Gwen, so they're copying me!).  However, there are several changes, some more obvious than others.  For starters, she's a drider (basically a spider centaur).  Her back story is extremely different from the other spider heroes (she doesn't have some sad childhood story).  She doesn't have the "With Great Power Comes Great Responsibility" theme.  Furthermore, the Greek gods add another layer of differences.

What I would like you to take from this is creating an original backstory (or one that is not identical to Bruce Banner) should probably be priority number one.  We probably will be quite lenient if you make his powers similar to the Hulk, but having a different backstory would help distinguish your character from the Hulk.  So I would stay away from Gamma radiation (or any form of radiation if possible).  Maybe stay away from turning into a "jolly green giant" would also help.  He (or she...just covering my bases here :sun) can still turn into a behemoth, but just make sure it is not "he (or she) turns into the Hulk.  Also, you could also take inspiration from multiple characters.  For instance, look at Captain Marvel (either Shazam from DC or Ms. Marvel from Marvel works, honestly).  When both of these characters originally appeared in comics, they had separate identities: Captain Marvel and Billy for the former and Ms. Marvel and Carol Danvers for the latter.  This still shows a way of portraying this duality between "smarts" and "brawn".

TLDR: Create a unique backstory and stay away from things that are not necessary to this idea of the dual personality (green skin, Gamma radiation, etc).  Also, you can also look at other characters with dual personalities (Shazam, Ms. Marvel, even any interpretation of Jekyl and Hyde).

You could simply do. Gamma + X = Hulk. Say ham sandwich = Ham Hulk. Or Spider Hulk, or Lizard Hulk as Marik said. Or magic Hulk, Cursed Hulk. Oh and you'll need a pouch sword. I wonder if anyone will get the reference.

I know pouches were a big 90's fad (thank you Longshot).  While I cannot recall any actual characters having a pouch sword, the web comic Spinnerette (a satire on the comic genre) is having a story arc at the moment that is sort of poking fun at "Spider-Verse" and the 90's Spinnerette has a pouch sword...
