Before I worked on ThunderCats, I knew nothing about animation. (I can think of a couple of people who’d say I still don’t!) My only experience of design stemmed from some time in advertising, and that confined largely to graphic design and illustration. ThunderCats enormously widened my horizon and one of its great
pleasures was getting out from under the endless words and working with artists – storyboard, character, background. The gamut.
I met Dennis when he was contracted to develop the secondary characters in Season Two. He had been working in animation for about ten years and was much admired for Galaxy Rangers. A terrific artistic talent, Dennis’ designs were very close to animation-ready.
(Anyone who has been lucky enough to compare Mike Germakian’s original concept arts with Kubo-san’s animation designs will understand what I mean by ‘animation-ready’ – and will see it in the designs included here.)
Even on Season Two, we were working under great pressure. Dennis was always calm and equable, by no means a given either in designers or writers. Certainly he made my life – and Lee’s – easier than it might have been. 
Shortly after he joined, he put his hand up to write some episodes. Shortage of time and opportunity confined him to just two: Shadowmaster and Well Of Doubt. I don’t know if he continued to write for other shows but, if he didn’t, he should have.
After ThunderCats, Dennis worked on a number of successful shows, notably ExoSquad (which still has a considerable fan base), Gargoyles and NASCAR Racers. He’s active on social media. He has a lot of up-close information about ThunderCats (and the business in general). Here’s a link to begin with: Dennis Woodyard.
