Dig, SolarBeam, Razor Cut, Leaf Blade, Pound, Tackle, Leer, and a few more I'm unaware of.
the cool kind my friends that's what they learn
you should be lucky to be a treeko! he can learn a variety of moves at the start, such as pound, absorb, bullet seed, and much more, which will help against groudon quickly
Solar beam. (grovyle learns leaf blade and it is like razor leaf)
at level 11
Learn pursuit with a male treeko then breed it with a female larvitar.
Lv 16 after he/she evolves from Treeko.
Yes. You can teach it either by TM or have it learn it at level 51 if you don't evolve it.
You must breed it with a Snover or Abomasnow that knows GrassWhistle (they learn it naturally by leveling up)
In Generation IV, Sceptile can be taught TM19 Giga Drain. In Generation V, only Treeko can learn Giga Drain at level 46. Treeko evolves into Grovyle at level 16 and Grovyle evolves into Sceptile at level 36.
it can learn Grass and Psychic moves
there is bprobably more but these are all i know: pound leer absorb screech leaf blade
Of course it can learn dragon moves such as dragonbreath and dragon dance and also can learn moves like twister and waterfall.
