Microwave (Freedom Force) VS Darg (Shadow Madness) - Know Darg semiprettyvaguely OK, it has been a while.
Akkadias (Beyond the Beyond) vs Robert the Wise (Might and Magic VII) - Akkadias is also vaguely familiar but no dice on Robert the Wise.
Sly Boots (Anachronox) vs Maya (Persona 2) - Know Maya way too well, only seen a small bit of Anachronox.
Xorphitus (Wizardry 6) vs Mammon (Quest 64) - Gut and memory.
Black Lord (Phantasie) vs Quanlee (Grandia Xtreme) - Know neither.
Ari (Okage) vs Stark (Shadowrun, Genesis version is where I got him from, may be in other versions) - AFAIK Stark is not in the SNES version, I don't remember the Genesis one enough to comment on if Stark was there or if he was the MC or the final or what. I remember it being fuzzy.
This needs more Lord British.
