yes.
But is it better than fire spin/overheat?
In short: Not really
But still a good option if you want machamp raids. But the question is: should I tm my only shiny moltres or keep it sky attack?
Ther are still superior options
And I would say no, even if you will use it
Okey dokey
@bagguille , @Jormdeworm , an issue.
@bagguille was the first to post it and put it in the General Disscussion.
@Kevin260709 posted it and then put in in the right category.
What should happen? Now there is two…
I literally just asked this earlier 
Why did you move my post?!
You should have kept @Kevin260709 ‘s one as it was in the correct area to begin with, @Jormdeworm
I am @Pokemon , not @Jormdeworm
Oh sorry I didn’t mean to reply to you 
Sky Attack Moltres would be better than Overheat Moltres against Machamp, it may surpass Rayquaza’s neutral DPS in clear weather.
The article was really helpful. I was considering TM-ing my 100% Moltres to get a fire-type charge attack, guess I won’t do this… But I WILL power it up, just because it’s a perfect legendary (my first one)…
Nice! Great achievement!
I wouldnt recommend it if you dont have a ton of dust lying around
I’m at 2.4 million, so a ton might be exaggerated. I don’t push any mons to max level all at once anyway (in most cases I lack the candy), I keep most power-ups for when I have a “power up x Pokémon” quest… 
@kRe same as you, I keep most power-ups for when I have a “power up x Pokémon” quest.
I might power one Sky Attack Moltres as a flying type attacker since it’s the 2nd best flying type now and will most likely remain the same after gen 4 hits
But here’s the catch: Heatran and Mewtwo outclass him
