What does Dash Rendar look like?

This is the official promo art for Dash Rendar, drawn by concept artist Michael Butkus (l.) and modified by LucasArts' Jon Knoles (r.):

And that leads us down two divergent design paths. The Kenner action figure, for instance, clearly favors Butkus' original (because sculpting and producing toys takes so long):

Logically, Knoles' was used directly on the box for the Nintendo 64 game, and later inspired the art on the PC version:

The Brothers Hildebrandt were working from the Butkus design when they painted the trading cards, so they hired a man named Tom Kyte to model for the character:

A model is the reason Knoles' design looks the way it does, too: since the game was being developed for the N64, and the N64 still used cartridges instead of CDs, there wasn't enough room on the cart to make 3D cutscenes; LucasArts hired an unidentified actor to stand in for Dash, then based the 2D art on him; however, the model was slightly younger than they wanted, so Knoles and the other artists had to age him up every time, leading to him looking slightly different in every scene.

That's still better than when the game was ported to PC and could have 3D cutscenes, because WHOOF!

That doesn't look much at all like either of the two designs we've seen so far. But oddly, it does look like the original storyboards used to plan the blocking of the cutscenes:

And wherever that super baby-faced design came from, it seems to have influenced Mike Sutfin's art in 2002's New Essential Guide to Characters, because certainly nothing else looks like that.

At least it got the hair color right. The comic clearly favors the Knoles design (making Dash look like a cross between Dennis Quaid and Bill Paxton), but made his hair blonde in the first book and black in the sequel:

The confusion over his looks didn't abate in subsequent years, either:

Top row (l-r): Rogues and Scoundrels TCG set (2004), Shadow Syndicate expansion to the Star Wars Galaxies TCG (2009), Topps Galactic Files cards (2012)
Bottom (l-r): Fly Casual RPG supplement (2015), Star Wars Armada: Rogues and Villains expansion (2015)

And now we've got the Black Series action figure.

Basically, Hasbro had tons of options when it came to designing their toy, and they somehow managed to get it absolutely, entirely, wrong.
