Harry Potter: My Plants Are a Little Too Savage

After being dropped into the world of Harry Potter, Leonard awakened a plant cultivation system. Any plant he touched could be massively enhanced, even absorbing materials from Magical Creatures to gain entirely new abilities.

Chomping Cabbage can't move? Only good for potion ingredients? Speed boost! Split! Shield breaker! Self-destruct! Cabbage, get in there and bite him!

Venomous Tentacula doesn't reach far enough? Dragon Breath! Poison Spray! Transform into an unfeeling artillery piece. What used to be plants that were only a little dangerous became the sworn enemies of wizards once Leonard got his hands on them.

Then the Second Wizarding War erupted. Voldemort led his Death Eaters in an assault on Hogwarts-only to be met by rolling hills of Chomping Cabbages and Whomping Willows sprouting legs and covered in dragon scales. The battlefield turned into an all-out Plants vs. Wizards war.

Voldemort: I'm losing my damn mind.
