Brian, to answer your question I need something to market to promoters when I fight so since I'm not a former pro wrestler from the WWE that is famous already why not be a Ninjutsu practitioner that does Muay Thai, Point Karate, BJJ, and MMA competitions?
Well, two things here. First and foremost, because none of those things are Ninjutsu!!! Training in them in no way whatsoever makes you a Ninjutsu practitioner! Secondly, such a mish-mash of systems will make you a very poor fighter, so although I would normally say "why not get famous by training hard in MMA and getting a name in amateur competitions, them moving on to semi-pro and eventually professional fights, I'm not saying that here as you are simply playing fantasy-land, and have little to no hope of really gaining any skill at all. I have made a number of posts here about why that is so, but frankly I feel it'd be so far over your head that there's little point going through it all again. Feel free to do a search, though.
But to make it absolutely clear, you in no way need to have come from the WWE to make it in MMA, in fact, it's often the other way around, MMA fighters are more likely to try to make it in the WWE, Brock and Bobby are a couple of the few exceptions. And in order to be a Ninjutsu practitioner, you need to train and practice Ninjutsu. Not the fantasy-world you're trying to inhabit here.
Also most of the people who have Ninjutsu backgrounds other than Jeremy Horn have quit doing MMA either because their bodies can't take it anymore or they never adapted their techniques to work in that environment.
Really? You spoke to them, saw their medical records, and know why they stopped?
I feel that you have absolutely no frame of reference in regards to Ninjutsu to be able to understand what I am about to say, but here goes... Ninjutsu is completely and totally non-competitive. All it's training is designed around very different needs and requirements, and as such using it as a base for a competitive use is rather like trying to use a radio to pick up television channels. Both are electronic devices with antenna's that pick up entertainment broadcasts, but they have very different uses, and to get a radio to work as a TV will need such major changes that it is rather pointless.
(This is how I see it if they can use Ninjutsu and compete in MMA why cant' I do it?)
Because you have absolutely no understanding, knowledge, skill, training etc in Ninjutsu!!!! Add to that the fact that if you are wanting to use Ninjutsu in MMA you have missed the point of both, you are really onto a really bad idea if you think they go together.
Also marketing is based on controversy any way so the more people that hate me or wants to see me get seriously hurt the more tickets I pull in for my bouts which means more money for me.
Train, get some skill, get some experience, get a bit of an amateur background, then start to look at anything which may include money. This is just another fantasy for you right now. You need more of an understanding of reality first.
Then factor in with this "home study course Ninja" persona I'm using I should be highly marketable to the public especially the local competition scene.
You would be marketable only as comic relief. And frankly, we don't need or want the publicity. Don't use our name, please, we do find it rather offensive.
If I'm really dominate also I can have something like Fedor has when people just go to my events to see if I add another body to my record or just to see if I can finally get broken and lose.
I get the feeling you would be "broken" rather quickly. If you were in any way able or willing to get the skills necessary for success in this field you wouldn't be looking for these "marketing angles" and short-cut approaches. This is still pure fantasy land. Get a grip on reality, really.
Oh well, I know I'm going to be hated anyway no matter which path I choose so mind as well get use to it.
Train in MMA for MMA!!! Really, don't pretend to be something you're not, don't bring in a name you have no right to be using, actually train in what you want to be doing, and you may well find that much of the "hating" stops. But again, this is just playing into your fantasy of being a hated MMA fighter, adding to your box office draw... really, get some reality.
Besides I hear positives and negatives to every style of the martial arts so no matter which path I take in the martial arts I'm going to be seen as a moron by some then some are going to respect me for doing it.
I'm going to be rather blunt here. You have no idea of any martial art whatsoever. And if we are going to compare who knows more and understands more about them, you're really going to be coming off second best. There's an old saying that you fight the way you train, so train for how you want to fight.... which means.... if you want to fight MMA, train in MMA!!!! Forget anything else, as you really don't have a clue!
