I’d be curious to see that list.
The Royal Guard from Curse is recolored as the Dark Elf Fighter, gets an upgrade to be most of the BC Fighters (Trooper, Veteran, Lord) in Secret, gets decked out in VGA as the Zhentil Warrior, and winds up demoted to lesser-sidekick as the Road Guard in FRUA.
The Dark Elf Lord from Curse changes complexion to become the Elvish Killer of Champions.
The all-purpose Fighter, Zhentil Fighter, and Zhentrim Fighter becomes Skyla in Champions and the Dread Guard from Secret.
The Red Plume from Curse becomes a Dark Lord in FRUA. The Dragon Master from Champions seems inspired by him.
The generic Curse mage in purple and blue (used with slight variants for the Zhentil Mage and Zhentrim Mage) gets reused in Champions (as the Zhentrim Mage variant), recolored in Death (black and blue for the black robe mages, yellow and blue for the Rogue Mage High) and finally in red as the Male Neutral Human Mage PC icon in FRUA.
(The Zhentil Mage is recolored to have black hair, whereas the Zhentrim Mage's body gets turned from blue to black with blue highlights but retains the white hair. This reflects the Zhentrim Mage's higher level and presumably greater age vis-a-vis the Zhentil Mage. The sort of nice minor touch that fell off as the series went on.)
Secret's goat-wearing Black Circle Mage becomes a Banite Cleric in Pools, and stays clerical as a Thenol Priest in Dark Queen and a Dark Disciple in FRUA.
The Vaasan Mage from Pools gets a two-pixel bust and a color change to red to become the Neutral Human Female Mage PC in FRUA.
Marcus from Pools of Darkness fills out a little to become the Evil Human Male Mage PC (and his recolored bald red counterpart, who isn't a default) in FRUA.
The Red Mage from Pools gets ported directly as FRUA's Master Wizard.
The Black Mage from Pools gets ported as FRUA's Necromancer.
The Blackrobed Spy from Treasures becomes FRUA's Magician.
The Thenol Wizard from Queen gains a beard to be FRUA's Wizard.
The Dark Wizard from Queen loses his frizzy hair and most of his levels to be FRUA's Theurgist.
Lord Manshoon from Pools (who you can't actually fight) becomes the High Priest from FRUA (if you wondered why they made a new icon), losing his magic ball.
The Evil Knight from Pools takes off the mask and becomes FRUA's High Thief.
The Dark Warrior from Pools gets ported directly in more or less a similar role as FRUA's Dark Knight.
The Vaasan Warrior from Pools gets a cape and plume change from yellow to red in Queen to be a Thenol Overlord. He then goes into FRUA in his original yellow as a Master Thief, and gets a shield with his red incarnation as the Dark Overlord.
The Zhentil Captain from Treasures gets a promotion to Dark Warlord for FRUA.
The Lordsman from Treasures gets ported directly as the Evil Champion for FRUA.
The Zhentrim Cleric from Curse becomes the generic fighter in Champions, is recolored a bit to be the generic fighter in Death, and is turned whitish-blue but still recognizable as the Human Male Good PC Cleric in FRUA.
The Zhentil Cleric from Curse fairly naturally becomes the Banite in Secret, but that's as far as he goes.
The Cultist and Priest of Bane from Curse (in green and black respectively) are recognizable as the Banite Cleric in Gateway and become the Human Female Good and Neutral Clerics (recolored to whitish-blue and purple-blue) in FRUA.
Curse's High Priest is demoted to a standard cleric in Champions but is quite recognizable with his flattop haircut as the standard Human Male Neutral Cleric in FRUA (which made me take a doubletake).
The Moander Cultist from Pools, on the other hand, takes a serious demotion and class change as the Warrior in FRUA. He doesn't have stink lines anymore, though.
Strangbourn from Champions becomes the Solamnic Knight in Death.
Curse's Looter is recognizable as Secret's Townsman.
Curse's Thief pretty naturally becomes the standard thief in Secret.
Muthtur from Gateway becomes the Master Thief from Pools.
Pools' Rogue becomes a Black Rogue in Queen, and the Thief and (recolored) Goon in FRUA.
Traned from Pools becomes a recognizable extra icon in Queen.
Pools' Brimwulf gets a recolor to join the living, and a shield, and becomes a Human Male Fighter in Queen and FRUA.
Vala from Secret and Pools is the basis for the Human Female Fighter from FRUA.
Shal from Pools becomes, oddly, the dwarf female fighter from Queen.
The Myth Knight from Pools becomes the basis for the human female fighter from Queen and the human female paladin from FRUA.
Skomp from Death is pretty clearly the base for Storm in Pools and FRUA, who looks an awful lot like the Dwarf Male Fighter from Queen and FRUA.
Nacacia from Pools is the base for the Human Male Ranger from Queen and FRUA.
Raizel from POD is the base for the Elf Female Fighter from Queen and FRUA.
