Castlevania's foray onto the Genesis sees two protagonists duke it out with Dracula and his minions: John Morris and Eric Lecarde. John Morris carries the famed whip, and Eric Lecarde wields a spear.
This run sees Eric Lecarde take his turn against the vast minions of Dracula.

For more precise details, see the authors' detailed submission text for Morris.
