Impostor

Multiple luchadors have used the name Impostor:

• El Cobarde II
• Impostor Jr. - son of El Cobarde II, changed name to just "Impostor" eventually
• Hijo del Impostor - son on Impostor Jr., later renamed to El Cobarde

There MAY be another "Hijo del Impostor" who switched to "Hijo del Cobarde" after the original changed to Cobarde NG. Presuming luchadb is, of course, infallible.
