Mii Gunner Matchup (Piranha Plant)

Matchup Summary (Win Condition and Game Plan)

Mii Gunner can pin down Piranha Plant’s large body and poor horizontal mobility with charge shots, missiles, and planted coverage, so taking a straight projectile war usually means getting cornered. If Plant keeps advancing on the same plane, Gunner can watch both the ground approach and jump-ins with forward air, up smash, and anti-air shots.
That said, Mii Gunner is much less stable once Plant gets close. Instead of trying to win from full screen, Plant does better by blocking once, placing Ptooie above Gunner’s next jump path, and using Poison Breath to dirty the retreat lane so Gunner is forced into a narrower jump-or-back-up choice.
The frame table shows that jab 1-3, forward tilt, up tilt, down tilt, dash attack, all smash attacks, up air, and down air are all punishable enough for grab, OOS uair, OOS fair, OOS nair, up smash, or up B, so shielding the close-range panic buttons is where Plant can steal momentum back.
By contrast, neutral air, forward air, and back air are mostly too safe to punish directly. If Plant swings out of shield every time, Gunner simply resets the spacing and returns to projectile control. KOs are more stable when Plant pushes to ledge and layers Ptooie, fair, up smash, and Poison Breath onto jump and high recovery instead of forcing center-stage reads.

Win Condition Checklist

• Do not sit at full screen trading shots. Walk and shield forward, then place Ptooie above Mii Gunner’s path so jump and retreat are both taxed before committing.
• Punish jab 1-3, forward tilt, up tilt, down tilt, dash attack, all smash attacks, up air, and down air on shield with grab, OOS uair, OOS fair, OOS nair, up smash, or up B whenever the spacing allows.
• After blocking neutral air, forward air, or back air, avoid forcing an immediate OOS swing. Keep the positional advantage instead and cover the next jump with Ptooie or fair.
• Once Gunner is at ledge, use Poison Breath to dirty neutral getup space and layer Ptooie or fair onto jump and higher recovery routes.
• Vary Leaf Floater height and timing on the way back so Gunner cannot line up charge shots, forward air, or down air on a fixed route.

Actions to Avoid

• Do not freeze near the corner and accept a long projectile exchange against charge shots and missiles.
• Do not swing OOS after every neutral air, forward air, or back air and give Mii Gunner a free reset to long range.
• Do not over-show Long-Stem Strike from far away and let projectile pressure and jump-ins beat the charge together.
• Do not recover at the same Leaf Floater height every time and invite pre-aimed edgeguards.
