Let's look at the moves Kangaskhan would normally use.I was close to using BoldCaps on you because even power drills aren't sufficient enough to get through your skull. Kangaskhan has perfect coverage with Return, Crunch/Sucker Punch, Earthquake, and Power-Up Punch. If Power-Up Punch were to be removed for some reason, replace with Fire move and PRESTO!
What he said.
I used a picture earlier explaining how I feel about this thread and those that don't listen. I won't repeat it again, but you should honestly know what you're saying BEFORE posting.
Oh the irony...
Power-Up Punch
Crunch
Sucker Punch
Earthquake
Fire Punch
Return
Assuming Return and Power-Up Punch are staples, this leaves us with only two available move slots. Which are usually the combination of Sucker Punch/Earthquake, Sucker Punch/Crunch, Crunch/Earthquake.
The set lacking Sucker Punch can easily be taken out by faster Fighting Pokemon.
The set using Sucker Punch/Earthquake can be easily countered by any Flying/Levitating pokemon.
The set using Sucker Punch/Crunch can be countered by steel types that can deal enough damage back.
