The Horned demon is the second-level Inferno creature in Heroes of Might and Magic V. It can be upgraded to a Horned overseer. The alternative upgrade, the Horned grunt, becomes available in Tribes of the East. The horned demon is capable of taking a lot of damage, with high hitpoints for a second-level creature. Unfortunately, its attack is quite low, meaning that while it'll be alive for most of the combat, it won't do much damage.
