>>>>Kid Buu Tips and Tricks<<<<

Pros and Cons:

+ Cancel System is his main pro.  It gives him an amazing and very powerful combo game, allowing him to build damage very quickly
+ Overall unpredictable.  With moves like his Neutral B, D Smash and Down B, he has great mix up potential
+ Powerful throws
+ Good gimping potential
+ Great recovery
+ Surprisingly solid defense

- Due to the Cancel System, Kid Buu's attacks are naturally slightly easier to DI out of
- He is extremely punishable if he wiffs an attack
- Substantial landing lag on his aerials
- Slow grabs (think Yoshi speed)
- Very light 
- Poor kill potential 

Tips:

- The main tip I can give you for playing as Kid Buu is to work on your button execution.  Think of him more like a Street Fighter character.  Timing and which buttons you press is key.  

- Don't use the same combo over and over.  It starts to get predictable and Kid Buu is anything but predictable.  Mix it up as much as you can.  Utilise the Down B and the Neutral B wiff to make quick exits out of combos you fear may not work as planned

- Use Kid Buu's aerials with caution.  They all have quite a bit of landing lag.  I'd recommend N Air and U Air for approach.  N Air because the hitboxes are long lasting and U Air because it's his fastest aerial and covers a large angle.  If you're feeling lcuky, go for a D Air gimp off the edge of the stage.  Be careful though, as this will result in an SD if you miss.
