Back before we had a 360, my cousin brought over Halo 3 and his xbox 360. We had never played Halo 3 before, so you could imagine how hyped I was to play. He had two remotes. My bro and him signed in. I wanted to join in really badly, so I took out his Guitar Hero remote and plugged it in. I got to the profile naming screen, and realized I could only use letters from one row. I took some random letters and came up with HOV. My brother saw it and said I should stick an O at the end of it.
HOVO was born.
My brother was playing on a Nintendo DS one day, and had a lightbulb go off. We were big fans of a game called Jet Set Radio Future, and he loved the character known as Zero Beat. He thought Ninjas were cool, so he stuck a ninja at the end of ZERO. His DS name became ZERO NINJA.
When we got our own Xbox 360, he wanted to use ZERO NINJA as his gamertag. It was taken, so he decided to get clever with numbers. 360 x 2 = 720, he liked the two rotation idea, and he stuck it at the end.
ZERO NINJA720 was born.
For some reason, I think HOVO was taken, or I wanted my tag to be similar to my bro's.
Thus, HOVO NINJA.
