Mario and Luigi Superstar Saga came out in 2003.

Mario and Luigi Bowser's Inside Story came out in 2009.

Mario and Luigi Dream Team came out in 2013.

The Black Cauldron came out in 1985, that's 18 years before the oldest of the games mentioned.

If anything, the three characters you mention are ripoffs of the Horned King, not the other way around.
