For Charizard's Final Smash, see Mega Evolution (Charizard).
When Lucario undergoes his Mega Evolution, his appearance changes slightly, though his size and movement do not. Lucario's Aura attacks are now at maximum strength, and do an incredible amount of damage and knockback. Lucario can still be damaged in this form.
In Lucario's Final Smash, it Mega Evolves into Mega Lucario. The attacks it can use don't change but its Aura abilities become more powerful than ever, letting it deal more damage and launch opponents farther. It can also resist being launched by other fighters, but the more attacks it takes, the sooner it will transform back.

Note: Mega Lucario does appear in Super Smash Bros. Ultimate when using it's final smash, but it's only for a few seconds shooting a blue beam downwards. See Aura Storm for more information. Plus, this final smash exists in Super Smash Bros. Brawl but Mega Lucario doesn't appear as Brawl was released way before Mega Evolutions became a thing.
