Is there any damage calculator with the new ORAS megas?

Question

I want to know a Pokémon that OHKO a full HP Mega Slowbro.

Answer 1

No but you can do this yourself.

On smogons calculator, you can change the abilities, stats etc. so using this, you can change the stats and abilities to that of the mega check.

P.S Mega Sceptile can ohko Mega Slowbro I think

Hope I helped.
