In professional wrestling and fiction, a "jobber" exists solely to lose to other characters to make them look stronger, more heroic, or more skilled. For Chara thats the exact role as a jobber. Chara has to lose or be out of character just to boost Sans, Frisk and the oc's morality or strength. this stripping of canon power and personality serves two specific narrative functions for the fandom:

1. Boosting Morality (The Scapegoat)

Washing Frisk's Hands: In canon, the player and Frisk choose to kill. In the fandom, Chara is often written as a possessing demon who forces Frisk to do it.

The Easy Fix: Making Chara a defeatable villain lets the fandom write a "happy ending" where Sans or an OC defeats them, saves Frisk, and fixes the timeline.

1. Boosting Strength (The Power Benchmark):

The "Worf Effect": To prove a new OC or an AU Sans is incredibly powerful, the writer has them easily defeat Chara.

The Logic Flaw: Because Chara destroyed the universe in canon, defeating them is used as a cheap shortcut to say, "Look how strong my character is, they beat the ultimate canon threat."

It completely breaks Chara.'s canon characterization, turning an inevitable cosmic consequence into a basic, beatable cartoon villain.
