Bowser's become my main in Smash 3DS. While he certainly has a lot of improvements to his agility, recovery, and KO power, he still has a lot of glaring weaknesses. Even so, Bowser makes up for the lack of pressure from a distance by having a sense of pressure just by his mere presence on the battlefield. Let Bowser get close to you, and he can kill you at as low as 55%. Fighting a projectile spammer like Mega Man is extremely difficult as Bowser. Luckily, Bowser has a lot more tools in Smash 4 to deal with them than in previous Smash games. Elite players still wreck me, but hey, there is always someone out there better than me.
