This is youtube.com/watch?v=GEnPuvENaSU but with Four (Luigi) and Six (Mario not to be confused with modern Six. So I think maybe the reason why Four treated X like he did was because his brother did it to him youtube.com/watch?v=B8UL0YmN6tg&t=462 4:06 so yeah Mario treated Luigi like crap which I think is also the reason why Four is how he is. Also despite being brothers they are also Evil ***** Six's fathers youtube.com/watch?v=3OjVzRpoWU4. So yeah Mario and Luigi belongs to Nitendo same with this six (cause he's Mario duh!) and Four belongs to BFB
