Ivysaur Matchup (Sonic)

Matchup Summary (Win Condition and Game Plan)

This matchup goes bad when Sonic runs straight into Ivysaur’s vine range, Razor Leaf lane, or anti-air space, because one clean hit often becomes a juggle or upward kill route against Sonic’s light weight, but Sonic can use the speed gap and spin feints to force those large hitboxes out first.
As the table shows, Jab 1-2, forward tilt, up tilt, down tilt, dash attack, every smash, neutral air, forward air, down air, Neutral B, Side B, and Up B are all punishable by Sonic’s Up B (4f) and often by his faster aerials, grab, or up smash as well, so blocked medium-commitment options should never be left unclaimed. By contrast, back air and up air mostly only lose to Up B, so swinging big after every shielded aerial just lets Ivysaur drift out and set the lane again.
The win condition is not to wait forever. Show spin, make Ivysaur jump or place a vine early, then hit the recovery frames with down tilt, grab, fair, or up tilt and keep the landing trap going. Ivysaur’s close-range cycling and landing escapes are not that strong, so once he is above or cornered, Sonic should stay under him and keep center closed.
For kills, it is more reliable to finish with ledge up smash, bair, and upward chase than to overchase offstage into down air or Vine Whip reversals.

Win Condition Checklist

• Do not throw spin in from the same height every time. Use charge feints and pullback movement to make Ivysaur commit to fair, Side B, or down tilt first, then punish the recovery.
• After shielding Jab 1-2, forward tilt, up tilt, down tilt, dash attack, any smash, neutral air, forward air, down air, Neutral B, Side B, or Up B, answer with Up B (4f) first and extend with fair, uair, nair, or grab when the spacing allows.
• After blocking back air or up air, avoid forcing a bigger punish than is there. Track the landing and the escape route toward ledge, then win on the second touch.
• Once Ivysaur is airborne, stay underneath and deny time to throw leaves again or walk back to center.
• Even at kill percent, prefer ledge up smash, bair, and upward chase over deep offstage commitments.

Actions to Avoid

• Repeating Side B or Down B from the same distance and driving directly into the vine tip or projectile lane.
• Throwing out oversized retaliation after every blocked back air or up air and giving Ivysaur an easy reset into midrange control.
• Letting punishable down tilt, dash attack, Neutral B, Side B, or Up B go unpunished and allowing the same zoning cycle to start again.
• Chasing too deep offstage for the stock and getting the whole exchange reversed by down air or Vine Whip.
