How about Violet Void?

I got that from Sonic Colors/Colours.

Pick a word from this speech:

Voilà! In view, a humble vaudevillian veteran cast vicariously as both victim and villain by the vicissitudes of Fate. This visage, no mere veneer of vanity, is a vestige of the vox populi, now vacant, vanished. However, this valorous visitation of a bygone vexation stands vivified and has vowed to vanquish these venal and virulent vermin vanguarding vice and vouchsafing the violently vicious and voracious violation of volition! The only verdict is vengeance; a vendetta held as a votive, not in vain, for the value and veracity of such shall one day vindicate the vigilant and the virtuous. Verily, this vichyssoise of verbiage veers most verbose, so let me simply add that it's my very good honor to meet you and you may call me V.

I think that this has proven that 'V' is the most awesome letter and as such deserves its place in my avatar alongside the most awesome colour (that being indigo, or 'purple' for those less interested in shades of purple than me).

I approve

Or what about Violet Vision? ^^
