They also changed up Lucario. Those who played alot of 2D fighters by companies such as Capcom, Arksys, or Lab Zero maybe familiar with the Magic Series. For those who are not familiar with it, the Magic series is essentially a game mechanic that makes characters perform combos or attack combinations in a Light-Medium-Heavy-Laucher-Finisher order... Lucario does alot of this and some! He also has EX variations to his moves!
As you can see here Lucario has Glowing Hands. That means he can use an EX special move! An EX move is a powered up version of Lucario's Special Attacks, the Project M peoples decided to change Lucario's Reward by Getting the Crap Beaten Out of You system, and change it to Reward by Kicking Ass system. Lucario's Attacks deal low damage, but his combos and finishers scale up quickly and effectively! Those who master Lucario's combos and use of EX specials will be a force to be reckoned with!
