 * Underestimating Badassery: Several people have underestimated him because he usually avoids conflict. In one case, a possessive immortal who hates that Methos slept with his slave tracks him down in the present day, using both Joe Dawson and as bait. Said immortal thinks Methos is a weakling and a coward, and expects to easily beat him. Instead Methos curb stomps him, and the last words the other immortal hears is Methos saying "Just because someone doesn't like to fight doesn't mean they can't."
 * Also, in the bad timeline shown in the last episodes where Duncan was never born, Methos went on one hell of a Roaring Rampage of Revenge when the Watchers are taken over by Horton, who begins slaughtering immortals and kills Methos' mortal lover in an attempt to get to him. Methos promptly teams back up with his old partner Kronos and begins leading the war against the Watchers. Their actions are described thusly: "They made the Russian Mafia look like choir boys."
 * What Could Have Been: Methos was slated to die but the producers like what the character brought to the series and he became a recurring character.
 * Would Hit a Girl: He has been alive for thousands of years before the idea of chivalry, after all.
 * He might have done this for fun when he was Death of the Horsemen, but in the present? They're gonna need to deserve it a lot.
