Here's a few for you:
"I want to live my dream, instead of my... my... REALITY!" - James Morgan, who's covertly snuck into the League's shortcut route, and has just discovered that Jessie's there, Pokemon Series One.
"I'm proud of you, my son." - Vegeta, moments before he sacrifices his life for his family in Dragonball Z.
"Sky Ring Cube? Sounds intimidating..." - A characteristically frightened Kid Muscle, from one of my personal favourite animes, Ultimate Muscle.
"New deal, Slade - I lose my friends, you lose your apprentice. And I know how you hate to lose." - Robin, who's just discovered the only conceivable way to prevent Slade from pwning his friends, in Teen Titans.
"HIT THE ROAD, DUDES!" - Tyson's grandfather, who's royally aggravated with 'leeches' bugging his grandson for sponsorship deals, Beyblade G Revolution.
"Pikachu - THUNDERBOLT!" - An ecstatic James who, with the help of Meowth and the rodent's case of amnesia, has managed to convince Pikachu that he's his trainer and gets him to fry Ash, Pokemon Advanced Battle.
Not strictly meaningful quotes, but they all symbolise a lot to me, so that's why they're here.
