Keeper (The Soul Garden)

The Keeper was a robotic gardener at the Garden on Titan. It had multiple gardening tools for arms. It attacked Rudy Zoom's expedition team for intruding, describing them as "foreign elements" that "must be weeded". The Twelfth Doctor deactivated the Keeper with his sonic screwdriver. He reactivated it again to trick it into freeing himself and Lady Takashi from being grabbed by Haluu vines. The Haluu Oksanna deactivated it. Later, upon realising she was really Lady Takashi's mother, Oksanna set off the Keeper's self destruct mechanism, destroying the Garden, along with Oksanna's lover Sythorr. (COMIC: The Soul Garden)
