So instead of them ruining the series like Boba Fett, we could see Legends material like characters like Jax Pavan (who fought Darth Vader and live), Ferus Olin (he and Obi-Wan went on adventures with ghost Qui-Gon Jinn and he fought the First Grand Inquisitor Malorum) come into the series since Star Wars Rebels failed to do it, also I wanna see these guys,
Under the control of Emperor Palpatine and Darth Vader, these Inquisitors were considered the highest ranking of the Dark Side Adepts, outranking the Emperor’s Hands, Prophets of the Dark Side, and lesser Dark Jedi.
