Thrawn isn’t the only legends character that deserves a canon storyline

Starkiller

Star Wars canon has a way of honoring legends lore in subtle ways in its material, especially when naming its characters. Jacen Syndulla is a semi-cameo tribute to Jacen Solo, one of Han and Leia’s sons in the legends storyline.

Galen Erso and Starkiller Base both also borrowed their names from a beloved legends Sith apprentice-turned-hero.

Galen Marek (a.k.a. Starkiller) was taken from his homeworld as a child following the events of Revenge of the Sith and secretly trained in the ways of the Sith by none other than Darth Vader.

Similar to canon events following the Jedi Purge, Vader was tasked with hunting down former Jedi and Force-sensitive children. He used Galen/Starkiller to serve as a trained assassin on his behalf, but his apprentice eventually turned on him and became a hero the galaxy would never forget.

Starkiller was responsible for the original formation of the Rebel Alliance, sacrificing himself to save Mon Mothma, Bail Organa, and company from his dark master.

In canon, the Inquisitorius have mostly covered his original purpose as a Jedi hunter following the Purge. But that doesn’t mean Vader can’t still kidnap a Force-sensitive baby and … oh wait. He already did. (See Darth Vader: Dark Lord of the Sith #19.)
