Haley: HEY! When's the last time either of you were the American Dragon? Well as the little troll girl currently filling the position, let me tell you it's stinkin' hard! I can't imagine doing it two more days let alone two more years. And to think about everything Jake's gone through; he's had to save magical creatures on a daily basis, lie to his own dad about who he is, say good-bye to the girl he loved, all to protect a mystical world that nobody knows about. He may be the American Dragon but he is also a 14 year old kid who just wanted a couple days off. If that makes him immature, fine, but self-serving? With all due respect to both of you, STEP OFF!!
Trixie suiting up in plate armor during "Siren Says" to face down a mind controlled Jake. Besides the fact she moves pretty fast in heavy armor (the suit alone would be about twenty kilograms (forty-four pounds), never mind the flail and round shield), she also holds her own fairly well and eventually gets the drop on Vikki.
Jonathan gets one in "The Long Weekend" and later in "Bite Father, Bite Son." The normally bumbling human dad fights to protect Jake from the Jersey Devil and vampires, respectively. He later helps save the day in the series finale as well.
