Female Mando, Dengar and anthropromorphic shark man. Seems like the show has more recurring baddies than it can use, actually. Especially when 3 episode long arcs eat away at the 22 episode seasons.
Though, I doubt shark dude will be recurring.
Dengar...there's a make or break character. Will they make him, the least cool of the classic six ESB hunters, more appealling...or will we see some teen Dengar loser?
Lux Interiour as a Ahsoka's love interest. A dead rocker? Wrong guy.
It's better they don't reveal too much. Because we get these previews and wait 6 months for some episodes to air, having been partially spoiled already. What should be new is old news.
