I mean I've always loved the Hulk and find him fascinating especially because he's not bad he's more or less just reactive towards threats and things that make him angry. Something I've often wanted to see would be a Justice League and or Titans story where a hulk like character is introduced and isn't evil just wants to be left alone but someone like Waller or Lex gets him riled up and he goes on a "rampage" whilst kicking ass and someone like Superman shows up he thinks it will be challenging but thinks he'll still win only to get his ass kicked and the Hulk at the and yells
"Strongest there is!" and before the Hulk character could finish Superman his Betty shows up pleads and Superman sees the Hulk character get sad and leaves the fight but not before yelling "Leave Hulk alone!" I don't know if there's a character like that in DC maybe Swamp Thing's the closest but I think it'd be interesting to see someone that powerful running around not intentionally causing trouble but for the trouble to follow him/her around.
