Well, Kong is trying to end the warring between the Kong and Mushroom kingdoms, but he's doing so by traveling around learning to get special powers via mushroom ingestion, while becoming better at beating things. So he's attempting a good deed, but I'm not 100% convinced he acts in a good manner. Beating things for the sake of beating things better, no matter how good the end result of this skill, doesn't scream good to me. So I'll say CG (CN leaned), though so long as there's beatings involved, I doubt he'll care much about anyone's alignment.
You've got, what, three pokemon so far? I'd just get the shotput enhanced; gives you plenty of time to see what your team needs, and it'll make you so much more useful in combat personally.
Unless you're only using the shotput as a backup...?
