Suggested by Sonic Wario has his Wario Man form at the ready in case things get hairy. Still, that won’t save him from Ken’s attacks. Being able to fly does help Wario keep his distance, but eventually he’ll need to close in and that’s when Ken will be victorious. Ken’s significantly better in close quarter combat than Wario to the point where he can win many different ways. Wario won’t be able to anticipate Ken’s moves ahead of time. Ken wins.
