Technically, you could argue that this is his first appearance in the show as it's set before the events of 'Breaking Bad' - but who cares, it's Gus Fring and he's back on our screens.
The first teaser for the fourth season of 'Better Call Saul' has landed online and sees Bob Odenkirk, Jonathan Banks and Giancarlo Espositio making their long-awaited reunion on screen together as Saul, Mike and Fring respectively.
Fring, of course, may not be the only 'Breaking Bad' character to make an appearance as creator Vince Gilligan has been pretty open about the fact that he wants both Bryan Cranston and Aaron Paul to make an appearance as Walt and Jessie at some point before the spinoff series ends.
'Better Call Saul' will return to Netflix in August.
