Ok, in my experiance the people i find difficult to approch are ness, Zelda, and someties lucas. If anyone has starts on a good way to approach, please post.
Now for the meat of this post:
some of the things i find very fun and very effective with bowser are:
Jump towards ur opponent with a side B, if it is missed or dodged, there is no lag time between the move and hitting the ground, which makes it perfect to Up B while on the floor, popping the opponent into the air. while in the air, u do Up airs, up tilt, and side B are some good ways to injure the opponent, keeping him in the air, due to Bowser having an AMAZING aerial game. Although, his moves are very slow, and will require some mindgames to hit.
another thing that i find effective is dashing at ur opponent, into an Up B when ur close enough. most of the time it will hit, pooping ur opponent into the air. But, if missed, u can still avoid being hit, or if the last part of the up B hits ur opponent, it can be a good spacer.
hope this helps
