create opposites from another dimension. for instance, I have a bastard of a stalker on these boards called, "Smart Cat". So I'll make him my alternate.
D0GG's doppelganger will be kat
SpandexMonkeyMan's doppelganger can be BlueJeanManMonkey
Britannica's is Americana
Fused's is Dispersed
Centurian's is Millenian
Jade Starlight's is Onyx Sunglow
Wednesday's can be Midday
Or you can make up your own damn alternates.
