King K. Rool Matchup (Roy)

Matchup Summary (Win Condition and Game Plan)

King K. Rool can slow the approach with crown and blunderbuss, then swing the match back with armor and huge single hits, but his defense and close-range speed are still poor enough that Roy gets enormous value every time he reaches point-blank range. Roy should not linger in front of the projectile wall longer than needed. He should burst through with dash speed, jumps, nair, and fair, then turn close-range hilt hits into damage and ledge carry immediately.
The table shows that jab 1-3, forward tilt, up tilt, down tilt, dash attack, every smash attack, Neutral B, and Side B are all punishable on shield by OOS uair (8f), OOS nair (9f), Up B (9f), or grab (10f), with stronger follow-ups available on the slower swings. By contrast, shallow neutral air, fair, and bair are less consistent immediate punishes, so Roy gets more by tracking the landing and the post-armor movement than by forcing an answer every single time.
This matchup is much easier when Roy finishes from ledge and offstage rather than waiting for weight to extend every stock. K. Rool’s recovery path is large and exposed, but Roy’s own recovery is also fragile, so edgeguards should stay selective and switch back to ledge trapping whenever the deeper chase is not clearly winning.

Full Move Frame Quick Reference

Win Condition Checklist

• Burst through crown and blunderbuss quickly with dash, jump, nair, and fair so Roy can start close-range hilt pressure before K. Rool stabilizes.
• After blocking jab 1-3, forward tilt, up tilt, down tilt, dash attack, any smash attack, Neutral B, or Side B, punish with OOS uair (8f), OOS nair (9f), Up B (9f), or grab (10f) every time.
• Do not mindlessly continue into belly armor after the first touch. Read the post-hit landing, shield, or panic option and hit the second opening instead.
• Convert every clean opening into ledge carry, then use fair, bair, Up B, and ledge traps to end the stock before K. Rool’s weight drags the exchange out.
• Edgeguard only when the route is clearly covered. If Roy’s own recovery becomes exposed, reset to ledge pressure and keep the advantage there.

Actions to Avoid

• Standing in front of crown and blunderbuss long enough for K. Rool to start the one-hit exchange he wants.
• Ignoring belly armor and repeating the same pressure string into the exact reversal window K. Rool is waiting for.
• Treating shallow nair, fair, and bair as automatic shield punishes and giving away Roy’s turn for free.
• Diving offstage too aggressively and turning K. Rool’s weak recovery into a losing stock race because Roy’s own return path is shorter.
