Curb-Stomp Battle: Implied against Cress, the Striaton City Gym leader, by Shane. Also implied by all of Nick's Pokemon by a Volcarona.
Saber vs. Zeus lasted all of one Ember and then Shock Wave attack.
Darker and Edgier: Than the regular Pokemon anime. In this, for instance, one of the heroes had to fight his way out of the villainous team's base with his bare hands, and the enemies are generally much better organized.
Disc One Nuke: Although it's not too powerful, since the Unova region had been cleared prior, all areas of the region are unlocked and various T Ms are now available to the cast. Most notable is TM 26 (Earthquake). Which everybody seems to want.
Dynamic Entry: Blackjack enters through a window to rescue Shane, even carrying a Garvantua Shield to intercept a Darkrai's attack.
Eagle Land: Zeal, Kaitlyn's Rufflet, is pushing for Type-1, but to some, Type-2.
Egg Sitting: Kaitlyn finds a Larvesta egg. Since then she has put it into an egg case since apparently it emits large amounts of heat. It has now since hatched.
Obfuscating Stupidity: Most of the time Nick spends with his Pokemon has this as his default mode.
Playing with Fire: Apparently a Larvesta egg emits enough heat to light even campfires. And now that it has hatched, it really likes to play with fire.
Worthy Opponent: Cobalion to Nick. Only time will tell if Virizion, Terrakion, and Keldeo have the same opinion towards whoever they meet.
You Shall Not Pass: Villainous example. Quatra and Siete attempt to pull this off. Unfortunately, they're guarding the wrong place. Johnny sets them straight.
