Kevin (Boss)

Kevin is an O.O.V.A.L. member and a boss in the Dark Storm series

Dark Storm
Since he's an early boss, Kevin has low HP and his attacks deal fairly low damage. However, he does have one attack that will threaten Stephen. Kevin will start this attack by riding his bike towards Stephen and preparing a Bob-omb attack. Press "A" at the right moment to deflect the Bob-omb and stun Kevin.

Another strategy is to use Eddy's "Schemin Dreamin" attack and keep barraging Kevin with coins.

Dark Storm 2
Again, Kevin has low HP, but has a different moveset. He only has three attacks; a weak dash attack, a wheelie attack, and a barrage of eggs. Dodge all these attacks and use your best attacks to bring Kevin down.
