Adamant Nature
- Substitute
- Return
- Sucker Punch
- Focus Punch
I don't choose my Kangaskhan to be too fast, the point of my move set is to set up sub.
Once Substitute is around, Focus Punch is just so much fun to use, and because of scrappy, later generations with those pesky ghost steel type Pokemon will be hit HARD. Return is for stab, I would replace it with Double-Edge for gens like 8 and so on, and if you also want it to hit hard. Lastly Sucker Punch, not only is it priority, but with my move set for Kangaskhan, there will always be some enemy Pokemon with 20 hp or lower, so you can get rid of the thing before it gets the last hit.
