At least you can fight her off in DC Universe Online, where the Spring Seasonal is currently up and running. Players will need to be level 10 to embark on quests to put that foliage back in its place.
By collecting seed pods and accomplishing various feats, players can thwart Ivy and earn new pets and base decor. Swamp Thing’s a part of this too, although he’s kind of the gassy part of spring. Good luck!
