No other Pokémon has the same type combination as the Zubat evolutionary family.
Zubat's evolutionary line seems to have a connection with Woobat's family. All the members of both lines are Bat Pokémon species (excluding Swoobat), live in caves or other dark places, and have no visible eyes at their respective unevolved states; furthermore, members of both lines reach their respective fully-evolved forms by friendship, and both have similar Shiny forms (with green main bodies). Also, Zubat and Woobat have somewhat similar English names, both having rhyming prefixes and bat as a suffix.
