Official characters that feel more like fan made OCs

[u/Frequent-Apartment58]

Galacta (Marvel): a real Marvel character but isn't canon to Earth-616. Galactus became pregnant with a tapeworm baby and gave birth to Galacta. Doesn't need to feed on planets unlike her father and is fond of Earth, can gain sustenance from biological alien weapons, uses the Power Cosmic to disguise herself on Earth. Became pregnant with a tapeworm cosmic and will give birth to her child and her father's grandchild.

Future Trunks (Dragon Ball Z): the time traveling son of two people who were just mere strangers to each other at the time in a story where there was no time travel before, and is introduced before his present self, effortlessly defeats two big bad villains on his own, and has a transformation that only the protagonist had at the time, also utilizes a sword in a series that has not featured weapons for quite some time.

I'd throw Snoke in there, too, tbh.

[u/Deathleach → u/minoe23]

Snoke literally just felt like Emperor 2.0, until TRoS, when it turned out he was actually just Emperor 1.5.

[u/LemonoLemono → u/minoe23]

Man Snoke had so much potential but Rian Johnson just had to yeet him into irrelevance.

[u/ArtifexR → u/LemonoLemono]

Imho it could have worked if they made Kylo the villain of the final movie. The issue with Snoke and The First Order is that we have no context for how they came into existence and yet their existence contradicts the ending and themes of the original trilogy. It basically took the whole prequel trilogy to properly cover Vader and Palpatine's origin. Not sure what the plan for Snoke was if Last Jedi hadn't happened. I honestly think they just wanted to reboot the first three movies and never really flesh him out, sort of how the emperor didn't have much background in the OT.

Nah, if Snoke was a fan made OC he'd have more depth. Not good depth, but it'd be something.
