It looks like you've got no choice. You're going to have to watch every anime in history and cross reference every androgynous spikey-haired character (ie. all of them)

Everyone other than Manus is wrong and stupid idiots and you should just resign yourself to this personal hell which you created by saving that image. I'm sorry but it really is the only way. If only you had considered the ramifications of your decision. If it is any compensation, you will only have to watch every anime series up until the day you posted this thread and not any released afterwards unless the Youtube user was a time traveler in which case you're really screwed.

Unfortunately he doesn't get off that easy, because 90% of anime made comes from books or games or manga. So there might be a game or book or manga with this character that already exists without an anime yet.

So, pretty screwed.

If Mercen-X just wanted to get sexy pictures of a blonde kid though, my recommendation is likely to get him the most results. I don't think Isaac from Golden Sun is nearly as popular as him.

Hahaha wouldn't it be funny if it were someone's "original" character featured in their DA works and perhaps the occasional fan fiction?

Looks like Isaac from Golden Sun to me.

The Vocaloid character Kagamine Len.

All are plausible within the realm of possibility...

I've given up. I officially declare the pic to be of Isaac as a Vocaloid... PS... I've started to appreciate Vocaloid. Somebody execute this thread.
