At least for these 2, we get more than just their name & appearance:

Dipplin is 40 cm to Applin's 20. I'd wonder how much of it is the stick, but it's also 4.4 kg to Applin's 0.5 kg; Almost 9 times heavier!
I wonder how it'll evolve. Will the apples for Applin's other Evolutions be accessible in Kitakami's Orchards?

Dipplin’s Ability: Supersweet Syrup
Dipplin’s Supersweet Syrup Ability appears for the first time in Part 1: The Teal Mask. When Dipplin first enters battle, the scent of its syrup spreads across the battlefield, lowering the evasiveness of opposing Pokémon."
Is making it activate upon Switch in & not costing a move slot (Like Intimidate vs Growl?) enough to make Sweet Scent viable...?
Then again, the opponent could just switch, so it's not like this is Pseudo-Gravity.
Sadly, I suspect this'll be more relevant in Doubles, as Pokemon often tries to cater to.

New Move: Electro Shot
With this Electric-type special move, Archaludon gathers vast quantities of energy and fires off a high-voltage bolt of electricity. Under rainy weather conditions, Archaludon can immediately fire off this attack without having to spend time charging it up."
Electric-type Solar Beam for Rain?
On one hand, I hope other Electric type get this. On the other, this better have some good upsides to compete with Thunder. Maybe it's Physical? Archaludon seems to get Electricity Manipulation, based on the text & images.
Duraludon can learn Thunder by TM, & has the 120 Sp. Atk to go with it, too.
Since Archaludon's an evolution of a 535 BST Pokemon, I wonder if it'll get any BST increase at all, or if it'll just get a rearranging like Scyther to Scizor.
