I've been using Mega Kangaskhan for a bit, and the PuP set is actually a pretty threatening sweeper. Unlike using an Arceus forme, using Mega Khan has very little opportunity cost (in Ubers, the only viable Megas are Mega Gengar, Mega Kangaskhan, and Mega Blaziken), and it is deceptively hard to revenge kill after it boosts:
+2 252+ Atk Parental Bond Mega Kangaskhan Sucker Punch vs. 4 HP / 0 Def Palkia: 280-330 (86.9 - 102.4%) -- 18.8% chance to OHKO
+2 252+ Atk Parental Bond Mega Kangaskhan Sucker Punch vs. 4 HP / 0 Def Kyogre: 306-360 (89.4 - 105.2%) -- 37.5% chance to OHKO
Two of the best Scarfers in Ubers are nearly OHKOed by +2 Sucker Punch, and outright OHKOed after Stealth Rock. Faster, frail threats are outright KOed by Sucker Punch:
+2 252+ Atk Parental Bond Mega Kangaskhan Sucker Punch vs. 0 HP / 0 Def Mewtwo: 612-720 (173.3 - 203.9%) -- guaranteed OHKO
+2 252+ Atk Parental Bond Mega Kangaskhan Sucker Punch vs. 0 HP / 0 Def Shaymin-S: 354-417 (103.8 - 122.2%) -- guaranteed OHKO
It also cannot be revenged by Extreme Killer Arceus:
252+ Atk Silk Scarf Arceus Extreme Speed vs. 0 HP / 0 Def Mega Kangaskhan: 163-193 (46.4 - 54.9%) -- 66% chance to 2HKO
Adamant Extreme Killer fails to net a guaranteed 2HKO (in other words, at +2 it cannot guarantee an OHKO), while in return Return OHKOes
+2 252+ Atk Parental Bond Mega Kangaskhan Return vs. 0 HP / 0 Def Arceus: 456-537 (119.6 - 140.9%) -- guaranteed OHKO
and +2 PuP deals heavy damage to non-bulky variants:
+2 252+ Atk Parental Bond Mega Kangaskhan Power-Up Punch vs. 0 HP / 0 Def Arceus: 240-285 (62.9 - 74.8%) -- guaranteed 2HKO
Furthermore, 105/100/100 defenses provide enough bulk, even uninvested, to take a hit and set up:
252 Atk Ho-Oh Brave Bird vs. 0 HP / 0 Def Mega Kangaskhan: 196-232 (55.8 - 66%) -- guaranteed 2HKO
252+ SpA Dialga Dragon Pulse vs. 0 HP / 4 SpD Mega Kangaskhan: 169-199 (48.1 - 56.6%) -- 88.3% chance to 2HKO
252 SpA Lustrous Orb Palkia Spacial Rend vs. 0 HP / 4 SpD Mega Kangaskhan: 217-256 (61.8 - 72.9%) -- guaranteed 2HKO
In return, Mega Kangaskhan outspeeds Ho-Oh and Dialga and can KO with Return and Earthquake respectively, while Palkia is KOed by +2 Sucker Punch.
It also deals heavy damage to bulky Steels which are hit neutrally by Earthquake:
+2 252+ Atk Parental Bond Mega Kangaskhan Earthquake vs. 252 HP / 252+ Def Ferrothorn: 208-246 (59 - 69.8%) -- guaranteed 2HKO
+2 252+ Atk Parental Bond Mega Kangaskhan Earthquake vs. 252 HP / 252 Def Mega Scizor: 217-256 (63 - 74.4%) -- guaranteed 2HKO
+2 252+ Atk Parental Bond Mega Kangaskhan Earthquake vs. 252 HP / 252+ Def Forretress: 198-234 (55.9 - 66.1%) -- guaranteed 2HKO after Leftovers recovery
Unfortunately, the PuP set is completely shat on by the Giratina formes and Ghost Arceus. Giratina-O is immune to PuP, EQ, and Return, and can use Will-O-Wisp to cripple Kangaskhan. Giratina can be hit by EQ, but takes a pittance from unboosted EQ and prevents Kangaskhan from setting up; the same goes for Ghost Arceus. Even replacing Sucker Punch with Crunch doesn't help much; they have the same BP, and while Crunch lets Kangaskhan hit Giratina as it gets burned, it doesn't do much:
252+ Atk Parental Bond Mega Kangaskhan Sucker Punch vs. 252 HP / 252 Def Giratina: 195-231 (38.6 - 45.8%) -- guaranteed 3HKO after Leftovers recovery
Furthermore, not having a priority move reduces its potency as a sweeper, as it is now liable to being revenge killed.
Overall, I'd say that while Mega Kangaskhan is nowhere near the threat level of the Extreme Killer, it is still an extremely powerful sweeper should it be given the opportunity to set up. Unlike, for example, Mega Blaziken, it has priority and doesn't rely on recoil moves to sweep, meaning it can take a huge hit during its setup turn and then attempt a sweep by taking out slower threats with Return and faster threats with Sucker Punch. It's biggest flaw is that not only is its sweeping set heavily walled by Ghost-types, it also cannot set up in front of them (Arceus and Blaziken can both set up with Swords Dance as the Ghost switches in, then deal heavy damage with Shadow Claw and Knock Off, respectively).
