Alternatively called The Last Of These Is Not Like The Others A character makes a list of items or individual and then deviates heavily with the last one. Basically this is the supertrope to Bread, Eggs, Milk, Squick and Arson, Murder, and Jaywalking and Arson Murder And Life Saving. One particular variation I've noticed is where you list a load of individual with some praise or titling (Grothar the Mighty, Elacor the Wise, Merthia the Powerful... Stinky Steve) which relates them to another trope that I can't quite remember the name of.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
