King K. Rool vs Marth

To effectively play King K. Rool against Marth, focus on utilizing your armor and heavy attacks to withstand his sword pressure. Use your Down Special to absorb Marth's projectiles and punish him when he overcommits with his aerials. Position yourself carefully to exploit his lag after missed tippers, and use your Forward Smash to punish his approaches. Remember to control the stage with your large hitboxes, keeping Marth at bay while looking for opportunities to edge guard with your crown or Gator Grab.
