Another show I'm glad I watched (on YouTube), though I needed to settle for most episodes in Spanish w/English Close Captions.

The hero forms have some serious detail in the designs. They took some work, especially when I accidentally used outdated reference on some tricky parts!

And the main cast was a blast to draw, including the sphere-centric layout, and maybe the cutest lizard/dino I've seen.
