Heroes from other games

This table contains all heroes from other NWC games, except Heroes IV, who appear in Heroes of Might and Magic III.

NWC liked reusing character names and designs. These alternate versions are marked in the table below by an olive background.

Heroes IV

The following are tables of heroes who are known to have survived the Reckoning and moved to Axeoth in the story of Heroes of Might and Magic IV.

† Rissa and Annavanta's portraits are incorrectly switched in Heroes of Might and Magic IV.

Kilburn the Knight from Heroes I and Heroes II featured in the beta version of Heroes III, but was cut from the final game. Letters from Roland in the manual from Might and Magic VI: The Mandate of Heaven establish that Lord Kilburn was killed by Kreegan forces.
Elderian's portrait in Heroes II is also that of Jarkonas VI, a major character and protagonist of The Price of Loyalty.
In Heroes II, Lord Haart appears in the campaign only and has Sir Gallant's portrait.
Gem, Crag Hack, and Sandro are the only heroes to appear in all four NWC Heroes of Might and Magic games.
According to Greg Fulton^{[ src ]}, Kyrre was originally meant to be a male elf. However, the portrait that George Almond painted for the hero looked feminine to most of the development team, so Kyrre was changed to female. Documents still referring to Kyrre as a man led to this hero being in the male side in Battle of the Sexes, and to being male in Heroes IV. "Kyrre" is a real given name for boys in Norway.
Despite being a goblin in Heroes III, Gretchin is mistakenly an orc in Heroes IV.
Sephinroth's portrait in Heroes IV looks more like Synca's.

The Price of Loyalty features a wizard named Solmyr, however it is a different character from Solmyr, as he is a human, and not a genie. Also, PoL's Solmyr is allegedly non-canon, as he only appears in a series of scenarios instead of in a campaign. Another Solmyr hailing from Ashan appears in Heroes VII.
Kastore, who features in the story of Forged in Fire , comes from the world of Terra and is not the Kastore from Heroes I - II who hails from Enroth. A third Kastore hailing from Ashan appears in the Heroes VI expansion Shades of Darkness and in Might and Magic X.
Maximus, who appears in All In , came from Terra along with Kastore and is not the Maximus from Enroth who appeared in Heroes I - II. A third Maximus hailing from Ashan appears in Heroes VI and Might and Magic X.
The Crag Hack who appears in M&M III and M&M VII also came from Terra along with Kastore and is not the Crag Hack from Enroth who appeared in Heroes I - IV. Ashan also has its own Crag Hack, who appears in Heroes VI and Might and Magic X.
A vampiric hero in Heroes of Might and Magic IV shares Luna's name, but there is no indication that they are meant to be the same person. Heroes VI also has a vampire Luna, but she used to be an elf instead of a human.
