character creation difficulties

"So!" I found myself saying to myself, i somewhat wondered why i was talking to myself but whatever.

"Let's see, i wanna write a Mario fan-fiction." Of course, the Mario bros. don't exactly have the most well-written story in the world. usually. but the RPG games complicate things tremendously.. as does the fact that that horrendous movie is actually canon. Yeah, i know.

"Let's see.. koopa side cause why not? I freakin' love bomb-ombs, o the main character needs to be a bomb-omb, because i love bomb-ombs." I thought to myself "let's see,all named bomb-ombs so far, for the most part anyway, have had names starting with 'b' and been a pun on bomb, boom, or other such words of bombs and explosions." i continued reasoning "wait, i should be a red bomb-omb!" But then i felt i would need to explain why i was Red and not black. Then i realised there were pink bomb-ombs, and red, and blue, and green... why were they those colors? I did not know.

"I think i can ignore that." and so i got to work. lines moved on thier own, words formed, the planets aligned (ok, maybe not quite that far), and eventually a red bomb-omb was sure enough staring at me. Only i could see him, for he'd been designed in my mind.

"Hiya!" it said to me.
"Hello, i think i will name you... Bomy." (Bom-e, in case you were wondering about pronunciation)
"Oh, that's cool" bomy replied cheerfully
"your personality is off..." I responded.
"pick me instead then!" there was suddenly a second bomb-omb, this one was a dark blue with a white scar over it's eye, i dunno how you can scar a bomb-omb, birthmark perhaps?
"oh no.." i realised where this was going...

and in case you were wondering, and if not then why are you still reading?
----------------------------------------------------------------------------
I couldn't hear my own thoughts anymore.
Hundreds upon hundreds of bomb-ombs all talking with each other, bitckering and argueing about which one deserved to exsist the most.
"guys.. enough.."
but they would not heed my words. Of course they wouldn't, they were me.

Then it happened, the boundaries of my mind collapsed, and they began to interact with the characters that already exsisted.
epic battles sprouted to life, alliances were formed as a crossover played before my eyes, a crossover that could never be. Other characters that weren't even mine got involved, playing out as i imagined they would, likely inaccurately.

a few minutes later and i'd gotten things back under control. the bomb-omb army deleted from my mind, blast zones and craters were everywhere, my other creations moaned in various amounts of pain and agony, and for a brief moment there was calm.
Then they got up, and began to talk again. the eternal chatting within my mind, something that would never cease.
