Moves, quick question

[~Metallica~]

Hello my skarmony had night slash that had 70 power and could do a little more then half damage on a gardevoir but then i teach it dark pulse, which has 80 power and it doesnt even do 1/4 damage

Same goes for my arcanine, flamethrower (95) does less then fire fang(65)

That's because Skarmory has 80 base Attack and 40 base Special Attack. Night Slash is a Physical move and Dark Pulse is a Special move.
Arcanine has 110 base Attack and 100 base Special Attack which makes it a bit weird, maybe it's because of it's nature or it's EV's.

Plus, Gardevoir has a higher Sp. Def than Def, so that's taken into account too.
Which might also be the case with Arcanine, if you were using Flamethrower and Fire Fang against a Pokemon with a high Sp. Def and low Def.
