Answer 1

Without Intimidate
> 252+ Atk Glalie Ice Shard vs. 0 HP / 0 Def Mega Salamence: 168-204
> (50.7 - 61.6%) -- guaranteed 2HKO

With Intimidate

-1 252+ Atk Glalie Ice Shard vs. 0 HP / 0 Def Mega Salamence: 112-136 (33.8 - 41%) -- guaranteed 3HKO

Answer 2

-1 252+ Atk Glalie Ice Shard vs. 0 HP / 0 Def Salamence: 148-180 (44.7 - 54.3%) -- 34% chance to 2HKO
This is calculated with Mega Glalie's base 120 Attack and Mega Salamence's base 130 Defense.
