Dread. That's what the Doctor's enemies feel when met with his legendary wrath. Aside from Eccleston's post-war incarnation the new series' Doctor's, while having their own intensity, had almost too much of a boyish look to them to match the fury that Capaldi throws out while play as Tucker. Fans got a glimpse of the furrowed brow and fiery gaze in the Day of the Doctor but it did only to leave fans wanting more, imagining the possibilities of what these eyes bring with them. Staring down the opposition with Tucker's burning eyes would make the times the Doctor got angry even that much more powerful which could enhance the darker vibe the show has been hinted at taking. Putting that extra dash in to the already explosive personality could improve almost every aspect of his character, all with just a change of facial expression. Imagine all the energy and power that can be channeled with the right look and lead to even more passion to the already noteworthy speeches from the character's new face.
Writer, musician, and history buff. I write short stories, comedy, and various other things. Have an almost unhealthy interest in all things Doctor Who and Star Wars with a little obsession time left for video games and music. Love horror novels and fantasy most of all, Stephen King is a huge inspiration.
