Igor

Igor is a boss in the Castlevania series.

Description
Igor is a regular hunchback enemy who accompanies the Creature into battle in both: Castlevania for the NES and Vampire Killer for the MSX. His presence was to emulate the classic Frankenstein movies of the monochrome film era and to add a little more challenge to what would have otherwise been a very unchallenging boss fight.

Like other hunchbacks, his appearance and attack patterns are no different from the normal enemies found throughout the game, albeit that his jumps are longer and faster than the others. However, Igor, unlike other hunchbacks, is invincible and can't die. Nonetheless, he can be slowed down by a well placed Holy Water attack for several seconds.

He vaporizes when the Creature is defeated.

Igor has not made an appearance since the first Castlevania game and its re-releases on other systems.

Trivia
