"Ferroseed, the Thorn Seed Pokémon. It defends itself by launching spikes, but its aim isn't very good at first. Only after a lot of practice will it improve." – Pokédex entry for Ferroseed.
"A Ferroseed seems like an odd Pokémon for Kaori Nakaseko to have." Kumiko commented, thinking back to her battle with Reina against the Elite Four member. "When you look at its spiky body, you immediately think that it's going to attack first and ask questions later. That contradicts what you've told me about Ms. Nakaseko's defensive battling style."
"Contrary to popular belief, Ferroseed and Ferrothorn are more defensive than offensive." Reina explained. "Their Grass and Steel typing allows them to resist most attacks, and their Trainers often equip them with Leftovers to help them passively recover health. In fact, the main battle strategy for Ferroseed and Ferrothorn is to first lay out Stealth Rock to damage incoming opponents, then plant a Leech Seed on them to drain their health, and attack whenever possible."
"Now that you say it out loud, it all makes sense." Kumiko was always impressed by Reina's comprehensive knowledge of battling strategies. "With how much you know, you're making me want to research what my own Pokémon can do!"
