Altro

Altro is a boy that lives with Kaoru, Joey, and the group at the Game Shop. He has a strange obsession with death and is labeled a psychopath for that reason. Everyone always calls him Noa as well since he trapped them in a virtual world and tried to kill them at the beginning of Season 2. His voice sounds like Noa's as well.

Appearance
Altro also looks a lot like Noa when it comes to his height and hair, but his clothes seem Gothic, probably showing his evil side. He is always made fun of for being short and is usually called a midget.

Relations with Others
Altro doesn't have that many relations as he is mostly shown talking with Kaoru only.

Kaoru: Though all the fangirls would say the two were gay with each other with all the fighting the two do, Altro really thinks of Kaoru as an older brother, which could also lead to people believing they were gay anyways.

Natalya: The two have similar views on how death is awesome and should happen all the time.

His Death
When Altro is changed into a vampire by Xavier, Altro targets Kaoru. When Altro and Kaoru battle out, Kaoru bashes Altro's head in with a rifle until his brain is crushed.

Deck
Altro's deck is a Dragunity and Mist Valley Deck which utilizes all the Dragon and Winged-Beast types to Synchro Summon the Dragunity Knight monsters as well as Mist Valley Thunder Lord. He also uses the Future Fusion/Dragon's Mirror combo to summon Five-Headed Dragon right away.
