Godzillo has the appearance of Ghido Goji, the Heisei Godzilla design from Toho's 1991 movie, Godzilla vs. King Ghidorah. He possesses a very dragon-like appearance, with a long tail and clawed paws for hands, although his head more closely resembles that of a bear. He is covered in dark gray scales and appears to be of quite a wide build, most prominently around his legs and torso.
His hero costume consists of a white coat with a high collar, ripped to match its tattered hem, and a pair of baggy white pants. Red flame patterns decorate his collar and most of the lower portion of his pants, all lined with yellow, and he wears a thick, golden belt with similar patterns around his waist. His clawed feet are decorated with bands of spikes, and he also wears silver-plated knee-pads.
It is noted that he has starred in many films. He is originally from Japan, but moved to the United States for unknown reasons.
Melissa and Izuku see him at the preview of the I-Island expo, where he greets the many onlookers and fans surrounding him.
- Godzillo's design and name are heavily inspired by the famous movie monster, Godzilla, which is owned by Toho.
- The Zillo portion of Godzillo’s name maybe a reference to Star Wars own Kaiju-like alien reptile known as the Zillo Beast.
- His current residence in the United States alludes to the 2014 American-produced movie Godzilla by Legendary Pictures, the most recent Godzilla movie at the time.
- According to the official website for My Hero Academia: Two Heroes, Godzillo is voiced by Godzilla, meaning his voice is recycled from Godzilla's roar from the Heisei Godzilla series of films.
- His Quirk name, Toho, is a reference to the company of the same name that co-produces and distributes the My Hero Academia TV series, films, and OVAs.
- His white pants and jacket appear to be a nod to iconic late musician Elvis Presley, who was regarded as the king of rock'n roll, much like how Godzilla is often referred to as the king of the monsters.
