Bowser vs Joker
Matchup Tips and Strategies
In the matchup against Joker, focus on controlling the ground to counter his aerial dominance. Utilize Bowser's neutral B to create pressure, forcing Joker to play defensively and allowing you to rack up damage since he is relatively light and can be KO'd around 80%. Be wary of Joker's edge-guarding capabilities, especially when he has Arsen; mix up your recovery to avoid his fair and potential footstool kills. When in the air, aim to capitalize on Joker's lower damage output by using Bowser's fair and side-B to dominate the aerial phase.

Keep in mind that Joker does not generate much percentage, face him in the air. I recommend the FAir and SIDE-B
