This Godzilla stands out from all the other Godzilla incarnations as he is completely green. His first three dorsal plates are unlike those in any Godzilla, but from the fourth downwards are similar to Godzilla's trademark maple leaf-shaped dorsal plates. Another notable thing is how his arms are very flexible, like late Showa Godzilla's, whose arm flexibility was human-like and different from the Godzillas of the rest of the franchise.
- Unlike his Toho counterpart, this Godzilla actually does breathe fire from his mouth.
- Godzilla fires red Laser Beams from his eyes.
- Godzilla has Super Regenerative Powers.
- Godzilla is very agile.
- Godzilla is an extraordinary jumper.

Hanna-Barbera's Godzilla does not use the iconic roar he used in the Godzilla movies in the show because that roar was trademarked by Toho Studios, so voice actor Ted Cassidy was brought in to voice Godzilla's roars, which sound significantly different from the roar used in the movies, on the show.
