Thunder Splicer:

This splicer has full command of ELectro Bolt, which allows it to fire Electric blasts at their enemies and when they aren't firing it, can use it to generate a directional shield that reflects bullets (similar to the final upgrade of the drill).

Reason - There aren't many with electric capabilities in Bioshock and Bioshock 2.
