What are some really bad OC trends/traits you could think of?

I need to take some notes if I’m gonna continue this story.

The OC has a really generic cutie mark with no thought put into it. I.e, a heart, a flower, a star, etc.

Even some of the canon background ponies fall into this trap, such as multiple Canterlot ponies in Best Night Ever bearing identical marks, not the mention the copies of Minuette and others in crowd scenes. It's obviously tedious to come up with original marks and designs for the artists, but in fanfiction and with the main character, it's just lazy

Hm.. okay. Anything personality or story-wise? Because that’s the stuff I’m really going to focus on.

I’d say one, but it’d kinda spoil what’s coming next in the story.

I dunno, they're all sheep?

Sheep? What sheep?

Sheep, as in, they will automatically go along with any plot device simply because they can

For example:

0:34 to 1:00

I see… kinda.

Though, if anything, I think the OC’s antics will often make the canon characters into sheep, as said canon characters will often go along with whatever the OC says or does without question, because the OC will always be in the right. Any character who doesn’t is often put in the wrong at best, and bashed and treated like a heartless monster at worst.

Obsessive, jealously (like, as their only defining trait), random bounds of singing (not really a personality, but something that gets on my nerves), the “nice guy”, overly enthusiastic, and that’s just a few I can name off the top of my head.

Ooh, good ones!

Especially the singing part, which I’ve seen in quite a handful of bad OC fics. I’m already thinking about someone attempting to sing like that, and Discord having to stop them “because copyright.”

Well, true

[Uknikorn]

I mean, in real life, the worst relationship is where you keep denyig all of the bad things that a person does to you, they hurt you emotionally and even physically. They are mean to you and to not care about or appreciate anything you have done to help them. They are more than a bad friend. They are someone who many people would not want to be around.
(But I don’t think you all want to hear about all of that,….) Either that more maybe just make a protaganist that suffers from “main character syndrome” where they are such a perfect person they are boring.(you said bad character traits,…)

[Changeling404]

Singular traits defining the whole character, and the character doesn't change or grow... (Not QUITE a :marry sue") and MAYBE even instead others must grow around them and bend to them and/or their opinions.
(KIND of like marks GF in the invincible anime)

Others having to suffer because of their actions, but they never have consequences to their actions and/or blame everyone else even though it was their fault.

A character is annoyingly self absorbed and/or oblivious to the needs of others yet everything always goes right for them.

[Crystal Hoof]

being overpowered, being completely useless, lewdng the cast, being an element of harmony

[Angel Midnight]

Having a planet-sized ego that's only fuelled by everyone around the character telling them how great they are, even if they make costly mistakes. (Mind, how do they even manage to make those costly mistakes if they're so OP?)
