Counter Tips

Short Hop > PK Fire to condition Incineroar to jump or shield. If they jump, Full Hop > PK Fire. If they shield, Grab.

Don't challenge Incineroar's recovery. You'll either get grabbed by Side B, they'll escape with their quick Up B, or even catch you in the Up B if you're too close.

Mess with Incineroar's recovery with PK Thunder.

If Incineroar tries to land on stage with Up B, watch out for the hitbox, especially if they have Revenge, as it can kill. Dash away, then grab them during end lag, and throw them offstage again.
