Description:
The energy of mega evolution was too much for Hydrapple to handle, granting its serpents increased strength and aggression, but causing the syrup apple the serpents inhabit to start overflowing. Now, not only does the syrup serve as an extremely durable protective barrier (if still extremely sticky), but it also emits a stench of overwhelming sweetness that slowly chokes out even the strongest warriors. Notably, the syrup's stench doesn't set in immediately. At first, you may not even notice the smell, but over time, it will set in, and when it sets in, you can expect nothing but trouble.
Syrup Bomb as a move is quite interesting on paper, being a move that lowers the opponent's speed over time. It obviously plays off of Dipplin and Hydrapple's very syrup-based flavor, but sadly in practice the move is basically never seen in a serious environment. Outside of its low power and extreme inaccuracy (sure, Supersweet Syrup exists, but considering it's only once per battle it's not very good), it also takes up a moveslot and any speed drops accumulated can be easily removed by switching out.
Sickening Sweetness is a way to exemplify Syrup Bomb's positives (lowering speed over time) with none of its downsides. It's an incredibly interesting way to subvert Hydrapple's weakness of extremely low speed, as it's a gradual effect instead of an immediate one-and-done. This ensures that even the fastest foes can eventually be outsped and overcome by Hydrapple, and incentivizes it to stay in longer and use its much improved defenses, somewhat useful (if a bit flawed) defensive typing, and access to Recover tank hits and rack up those speed drops. And unlike Syrup Bomb, the speed drops can't be easily removed via switching, since they will come back as long as Hydrapple is on the field. All of this ultimately seeks to augment Hydrapple's playstyle of tanking hits, healing off the damage, and eventually overwhelming the opponent with your special attacks. There's a lot you can do with this mon, from your prototypical NP user to a standard tank, to even abusing the famed SubSeed combo with the ability. Substitute can shore up damage for Leech Seed to damage the opponent and heal back the lost HP from having to set up a Sub, and the speed drop over time cripples the opponent and ensures that they will be too slow to be able to break past Hydrapple's Substitute (at which point you can finish them off with a powerful attack or let the Leech Seed chip damage finish them). Sure, even with the ability in mind, you still need to watch out for mons that pack super-effective moves, but the speed drops can ensure that even in the situations where you get forced out, those mons can also be forced out and by your allies too, as a single speed drop can be extremely undesirable in the long term.
And all of this is just in a Singles format, mind you! In Doubles, Sickening Sweetness can serve as an extremely potent form of speed control, essentially being the equivalent of using an Icy Wind every turn. Sure, Grass/Dragon isn't the best typing to have (what with all the Flutter Manes and Mega Tinkatons running around with no Tera to save you), and it lacks good spread moves, but even then it still has its perks. Notably, its typing provides an Earthquake resist (and notably no Heat Wave weakness for a Grass-type), and the other miscellaneous resists to Water and Electric can occasionally come in handy. To this extent, it can provide some form of support for your team in the Breaking Swipe, which while weak, can help cripple physical attackers, letting Hydrapple stay on the field longer. In addition, while it lacks proper spread moves, it can still dish out potent single-target damage, and its defenses are good enough to mitigate its defensive shortcomings, letting it function as a powerful support option and a flawed yet potentially effective attacker.
