Would anyone mind that is fluent in Japanese translating something for me from English to Japanese? I would like to say something like The School of The Mighty Dragon God. I know this is really random to ask, but I am trying to create a stable for my wrestling game and I am trying to come up with a really cool name for it.

Google Translate?  Would probably result you with Maiti doragon kami no gakko.  Actually I checked.

Kyoudai Ryu Jin no Ryuuha!  å¼·å¤§é¾ç¥žã®æµæ´¾ if you want it in official writing.

Of course I am assuming that this school you're talking about is a martial arts school, else this would sound funny if you were actually referring to a real school.  If it is a real school, then substitute "No Ryuuha" to "Gakuen".

Thank you very much durendal! And yes, the title would refer to a fictional type of mixed martial arts/wrestling dojo that I was specifically creating for my wrestling video game. I have been playing wrestling video games for years and have always wanted to create my own fictional wrestling school for my created characters! Currently I have settled for the title "Grand Ryujin Disciples" because it is more easier to say and remember.

what about Dai Ryujin Ken, or Oh Ryujin Ken? 大竜神拳

It's not exactly what you asked for, but has the same connotations.

it is essentially 'great dragon-god style'. (style is usually linked to school)
