"
Batteryman" (
Denchimen) is an
archetype of
LIGHT Thunder monsters. Initially, "Batteryman" Decks were
OTK Decks that focused on
Special Summoning three copies of "
Batteryman AA". This allowed the player to then use "
Short Circuit" to clear the opponent's field and then
direct attack for a minimum of 9000 damage. However, following the release of "
Batteryman Fuel Cell" and "
Batteryman 9V", many different variants are possible, such as a "
hunder" variant.
In
Yu-Gi-Oh! 5D's Dexter's Deck contained at least one member of this archetype, "
Batteryman AA".
