Paralyze now halves speed instead of 1/3rding it.
You can insert Pokemon into your party as you catch them even if it's full, and also check their summary.
Z-moves are power and phys/special depending on the base move. Gigavolt Havoc from Thunderbolt is 175 base power. Nuzzle it has 100 and is Physical. Electro Ball it is 160 and Special
Ash-Greninja's Battle Bond boosts the power of Water Shuriken, which is now Special. If the demo version's is absolute it gets +50 to both Attack/SpAtk (145/153) and +10 Speed (132). So a slightly more potent, less consistent not-Mega Mega. It's basically like just giving it a souped-up Moxie+. Downside is that it seems "Everyone gets the same Greninja: 20/31/20/31/20/31 IVs, 128 Atk / 128 SpA / 252 Spe EVs, Hardy Nature, Souvenir Ribbon"
