Welcome to Gaia! ::

well, from my guess, maybe they had their head shaved for some reason, and since they had no vectors they couldn't prevent it from happening, but also since the females have their hair still maybe coz the government wouldn't even dare trying to get rid of it due to the vectors the females have.

and to be honest yeah males can be pretty useless, and to be honest....im a guy myself crying

aight, i was readin da comment you ladies posted on page 1 and i gotta say dat dat was a load of BS. i am not like most men dat you ladies are always complainin about. i have never hurt a girl in mah life, but you girls seem to want to hurt me. being rejected all da time, cuz i aint got no money, or cuz i aint popular, or cuz i aint got da nicest stuff. so yeah, ya'll should learn about peoples befo ya start judgen dem like dat. and on a further note, baseball bats are very usefull.

the male should have red hair, coz it will be boring if there bald all the time? gee i didnt have my hair then....gee i think it would be the end of the world for me......

The men wouldn't make good diclonius, because they aren't as sly as women. Men form of fighting/killing is brut force. Women usually use a silent,and surprising form of killing, like poison. So the vectors for the women are are silent, because the victims don't know about it and can't defend themselves from it. So that my reason why men wouldn't make a good diclonius

males dont need vectors just 50.cals that seems to go through the females defences. or hid themselves in a pickle jar

Yes I think the way they made the Male Diclonius in the Anime usless to a point. Although you have to remember they weren't real Diclonius Men. They weren't born with the horns. The Chief, and Professor (Father & Son) Made a Diclonius Virus that they used to give themselves horns. The Professor also mentioned that the Vectors were still under study. There for they could not give themselves Vectors. Also for them being bald.. I'd say they lost there hair b/c of the Diclonius Virus they used on themselves! The whole point is that Chief & Professor Kazagarwa.. ( I think that is how you spell there name) They wanted to change Humanity. They made each other into Half-Diclonius so they could.. so called breed with Lucy(Queen Diclonius), and change the world forever. So the Guy Diclonius sorta had a purpose! sweatdrop Opps I think I got abit carried away in my reply. Sorry!

Well, if they were made they must have some purpose... but I guess they won't have as big of a role as Lucy or anyone else.
