Jellicent @ Sitrus Berry
Ability: Cursed Body
EVs: 252 Atk / 252 Def / 4 Spe
Bold Nature
- Will-O-Wisp
- Scald
- Ice Beam / Shadow Ball / Hex
- Recover
With the combination of its great bulk, typing and having the access to WoW and Recover, Mr.Pringles can handle pretty well Mega Kangaskhan, being immune to its main STABs and easily stalling Sucker Punches.
The only real ways that Kangaskhan has to hit Jellicent are with Earthquake or Scrappy Double-Edge, 4HKOing with Earthquake and 3HKOing with Double-Edge if Will-O-Will misses. This, of course, before it gets Burned.
252+ Atk Parental Bond Mega Kangaskhan Earthquake vs. 252 HP / 252+ Def Jellicent: 69-82 (33.3 - 39.6%) --
guaranteed 4HKO after Sitrus Berry recovery
252+ Atk Kangaskhan Double-Edge vs. 252 HP / 252+ Def Jellicent: 82-97 (39.6 - 46.8%) -
- 88.7% chance to 3HKO after Sitrus Berry recovery
Burned: 252+ Atk Parental Bond burned Mega Kangaskhan Earthquake vs. 252 HP / 252+ Def Jellicent: 34-40 (16.4 - 19.3%) --
possible 7HKO after Sitrus Berry recovery

Even with the rare Crunch or Thunder Punch (
before being burned) Kangaskhan has less then 1% chances to 2HKO Jellicent, with Crucnh (widely missing it when burned) , and will always miss the 2HKO with Thunder Punch.
252+ Atk Parental Bond Mega Kangaskhan Crunch vs. 252 HP / 252+ Def Jellicent: 110-132 (53.1 - 63.7%) --
0.6% chance to 2HKO after Sitrus Berry recovery
252+ Atk Parental Bond Mega Kangaskhan Thunder Punch vs. 252 HP / 252+ Def Jellicent: 104-124 (50.2 - 59.9%) --
guaranteed 3HKO after Sitrus Berry recovery
Burned: 252+ Atk Parental Bond burned Mega Kangaskhan Crunch vs. 252 HP / 252+ Def Jellicent: 55-66 (26.5 - 31.8%) --
Miniscule chance to 4HKO after Sitrus Berry recovery
Burned: 252+ Atk Parental Bond burned Mega Kangaskhan Thunder Punch vs. 252 HP / 252+ Def Jellicent: 52-62 (25.1 - 29.9%) --
guaranteed 5HKO after Sitrus Berry recovery
And all those calcs are made with Max Atk, Adamant nature. With a Jolly nature or less attack the match up will be even more ideal for Jellicent.
Things get even better if Cursed Body activates (and vs Parental Bond, this ability will have 51% chances to activate).
This is why, imo, Jellicent pretty much tanks Mega Kangaskhan, always checking it with Burns.
Bonus Calc: 252+ SpA Parental Bond Mega Kangaskhan Thunderbolt vs. 252 HP / 0 SpD Jellicent: 86-102 (41.5 - 49.2%) -- guaranteed 3HKO after Sitrus Berry recovery
I don't know if there are 252 SpA kanga out there, with a Modest nature, but you never know.
The only thing i would fear from a Mega Kangaskhan is Shadow Ball, still missing the 2HKO, but having 1/3 chances per round to lower Jellicent's Special Defense.
