Let's see I first got into Fire Emblem back when I played an unfinished fanslation of Gaiden on the NES. A few years later, my brother found Fire Emblem 7 (just called Fire Emblem here in the U.S.) at a Gamestop on the shelf and bought it. I was so hooked I convinced him to buy his own copy and that was all she wrote for us.
As for favorite character, off the top of my head I'd say Hector is one of mine. He's brash, reckless, but loyal to a fault.
Hector: You’re not Marquess Laus’s assassins, are you? You’re too good, too professional. Nothing like those idiots over there.
Wire: You’ve no need to know, little Lord Hector. A fool like you, sneaking out of the country alone… You’ll go missing, never to return. Your body will never be found. Tidy story, eh? Ha ha...
Hector: Tsk tsk... Looks like your luck’s run out.
Wire: Our luck? What are you...
Hector: You see, I’m about as angry as I’ve ever been. I doubt that even a dozen of you could slow me down. Prepare to die!!!
Hector: ...Are you the one responsible for
death?
Uhai: ......And if I were? What would you do?
Hector: I’m not entirely sure... But I do know that you would not draw another breath!
Lloyd: You there, who are you?
Hector: Marquess Ostia’s brother, Hector! And you, lout?
Lloyd: The Black Fang commander’s son, Lloyd Reed... You remind me of my brother. Something about you...
Hector: Huh? What are you talking about?
Lloyd: My brother, whom you killed. My brother, Linus...It’s none of your business......
Hector: I have a brother, too. If someone killed him, I would make sure his killer paid dearly and suffered long...
Lloyd: ......Well spoken. If you don’t want to give your brother cause to mourn, you’d best fight well......Prepare yourself.
Hector: Ah!!
Linus: Hey, you! You think you’re tough, don’t you?
Hector: Tough enough to cleave you in two.
Linus: I am Linus Reed, son of Brendan Reed. You killed my brother, Lloyd! Take this! Rrraahh!!!
Hector: I am Marquess Ostia’s brother, Hector!! And I don’t know about Lloyd, but I’ll sure kill you
