Giga Torchwood is the very first boss plant exclusive to Graveyard Ops and the Backyard Battleground in Plants vs. Zombies: Garden Warfare 2. Giga Torchwood is based on Torchwood's design in Plants vs. Zombies 2. He has both long range and short range attacks, making him similar to the Giga-Gargantuar.
