What are your thoughts on Vaneé? Darth Vader's castle servant?

I thought he was really cool and mysterious in Rogue One, he was very funny and entertaining when voiced by Tony Hale in Lego Star Wars: Terrifying Tales, and I like his creepy personality in Cavan Scotts Vader's Castle Halloween comics, (in which he is the villain of).

I made this post because he is probably going to appear in Charles Soule's upcoming comic series Legacy of Vader, so in preperation for that I would like to hear what you think of him as a character.
