No.

I think the problem is that you get people who make characters based around powers instead of characters based around well, character.  Instead of taking the role of a character, they take the role of themselves with super powers.  This is why you get those OCs the OP mentions.  You get a kid who gets a hard on for some kind of power (like magic or the biggest gun/sword ever that does 999999999 damage, or in some cases you get the person who decides he wants to be a dragon that eats people...  Don't be that person), wants the powers and makes up a character that has lots of powers without regard for context or setting.  And from there you get a total mess.  I've been in RPs where that pretty much describes literally every character within and it's actually really boring since all the conflicts get resolved by everyone spamming super abilities at anything remotely threatening.

Ideally most people who decide to get better at fiction writing grow out of the mentality, but you also get quite a few people who don't.
