Matchup Summary (Win Condition and Game Plan)
Mythra can tear through the front with run speed, neutral air, forward air, down tilt, and dash attack, then keep the scramble going with grab or Up Smash once Plant is stuck blocking. The more Piranha Plant swings big first in center stage, the easier it is for Mythra to turn whiff punishes into long advantage.
The stable answer is to stop racing her in open space. Ptooie should sit over Plant’s head to cut off jump-ins, while Poison Breath narrows the ground lane and pushes Mythra toward the ledge first. Mythra still struggles to kill and her recovery is fragile, so even at high percent Plant gets more value from surviving the burst and cashing out with fair, Up B, or Up Smash once Mythra is offstage.
The table shows clear punishes on Jab 1-3, Rapid Jab Finisher, Up Tilt, Dash Attack, every smash attack, and Side B, where Grab, OOS Uair, OOS Fair, OOS Nair, Up Smash, and Up B can all take the turn back when Mythra overcommits or throws Photon Edge carelessly.
Forward Air, Back Air, Down Air, and close Neutral B are still too safe to challenge every time. It is stronger to keep the punish list tight, then use Ptooie and fair at the ledge to pin down Mythra’s height choices and jump escape before her speed can reset the stage.

Win Condition Checklist
- Do not chase Mythra through center stage. Keep Ptooie above Plant to cut off jump-ins, and use Poison Breath to narrow the dash lane on the ground.
- After blocking Jab 1-3, Rapid Jab Finisher, Up Tilt, Dash Attack, any smash attack, or Side B, answer immediately with Grab, OOS Uair, OOS Fair, OOS Nair, Up Smash, or Up B.
- After blocking forward air, back air, or down air, do not swing automatically. Watch the fade-back or landing spot first, then place Up Smash or the next Ptooie where Mythra has to end.
- Treat kills as a ledge and offstage problem, not a center-stage brawl. Use Ptooie, fair, Up B, and Up Smash to collect the narrow recovery routes once Mythra is forced out.
- Even at high percent, stay calm enough to take center back instead of panic-jumping, because Mythra still has to work hard to finish stocks cleanly.
Actions to Avoid
- Throwing out big Up Smashes or Long-Stem Strike in center stage first and giving Mythra free whiff-punish starters.
- Trying to punish every blocked forward air, back air, down air, or close Neutral B and getting clipped by a grab or Up Smash on the failed answer.
- Repeating Ptooie and Poison Breath at the same height until Mythra simply jumps or dodges through and forces close-range pressure.
- Overchasing offstage so hard that Mythra’s return route or Side B escape takes the ledge situation back for free.
