Yes it is true. At first I didn't want to belive it, but once all the facts are revealed, the truth is obvious. 1st of all, Luigi is italian, and Italy allied itself with nazi Germany during world war 2. Also both countries are facist.
2nd of all, Even tho Luigi is taller, in better shape, and can jump higher than mario, he is never the top banana. This can cause high amouts of rage and hatred, and if these emotions go unchecked, they will only become fearcer. He could have easily become a nazi with this much anger.
The third point is that Nintendo is located in Japan, which was nazi Germany's other allied state during World War two.
#4, Now luigi's anger of Mario is spawned from his jelosy of Mario. Jelosy of what he has and what he is. So once Luigi saw Mario (in the image below) he must have thought that Mario was powerful like that. Thats another reason.
|Its Hitler Mario
#5, listen tho this audio clip below
"I'ma Luigi, number 1" This obviously show how Luigi belives in his supremacy, over other racers in mario 64, and other Races!
#6, Lets just look at the chemical formula of the Mushrooms. I think it speaks for itself.
#7, All though it wasen't widely known, King Bowser was in fact a Jewish homosexual Gypsy.
#9, look at this footage!
