Poison Plant

The Poison Plant (ポイズンプラント) is a Heartless Boss exclusive to Kingdom Hearts 358/2 Days. Similar to the Creeper Plant, it appeared before Roxas in the Underground Concourse in Twilight Town. Xion aids Roxas in this battle, using Magic rather than a Keyblade. The Poison Plant is in the same family of Heartless as the Fire Plant, Creeper Plant, and Blizzard Plant. Poison Plant is fought on Days 23, 51, 76, 95, 151, and 353.

Kingdom Hearts 358/2 Days
These large plant Heartless are rooted to the ground. They strike from afar with poison shots that cannot be blocked. ''At close range, they'll attempt a head-butt, after which they'll be wide open. They are also susceptible to Fire magic.''

Strategy
At the start of the battle, the Poison Plant fires a ball of poison in your direction which can blind you or take away your jumping ability. Try jumping to dodge it, and then use Lock-On. You may then begin to hammer the stationary boss with the Keyblade. Use caution, as the boss soon begins to slam its head against the ground to deal damage. It is impervious to physical damage when it does this, so do not bother to attack it. It lasts for a few seconds, so use this advantage to get away and use magic or heal yourself. The slamming attack can be prevented with a combo finisher. The Fire Spell will also burn the Heartless Boss, dealing extra damage for a few seconds after the initial hit. Do not worry though, if you do not do this, as Xion often uses Fire Magic on her own.

Bring as many healing items as possible into this battle, and remember to dodge.

Trivia
