When this card is Summoned: You can add 1 "Batteryman" monster from your Deck to your hand, and if you do, this card's ATK and DEF become double its original ATK and DEF. You can only use this effect of "Batteryman 9-Volt" once per turn. During your End Phase: Destroy this card.
A fast-paced archetype with lots of searching and Special Summoning. Batteryman 9-Volts is a good in-archetype searcher and beater. You can Special Summon Batteryman 9-Volt with Batteryman Charger and Batteryman Micro-cell for even more searches. Or before Batteryman 9-Volt destroys himself, you can use him as cost for Batteryman Fuel Cell’s effect.
