How do you call a Replacement Scrappy that has total no respect for his predeccesor? A fictional example using CSI: After replacing Gil, Raymond Langston is constantly saying bad things about him like "Gil was a terrible boss", "He couldn't do things right" or "Things are now better with me".

Does this still count as this trope, or should it be another one?

Can we switch it to "Scrappy Replacement"? "Replacement Scrappy" sounds like a scrappy replacing another scrappy. "Scrappy Replacement" is Exactly What It Says On The Tin though, so it's clearer.

Edit: ... Never mind, it'd be just as bad.

Most of the Tekken examples don't belong here. Characters being replaced is only half the trope. Almost all of the replacements mentioned are well-liked.
