There’s no “h” in “Thomas” so you know he’s science-fictiony.  Those who experienced the Thrawn Trilogy through the novels tend to bristle at the visual translation of some of the characters in the comic book adaption.  The depiction to the right does not find my mind’s eye image of Gillespee.  I have seen fan art depictions that feel more appropriate.  Nevertheless, Hasbro would need an official visual representation and this is what we’d get.

Gillespee doesn’t appear until the final chapter of the trilogy, but is instrumental to the final outcome.  Together with Talon Karrde, Gillespee arranges a gathering of smugglers at Whistler’s Whirlpool to form the Smuggler’s Alliance and assist the New Republic in the fight against the resurgent Empire.
