The Mutant Named Godzilla

(Mutated Human) Gojira - The original monstrous mutant that revealed the existence of mutants to modern humanity. Not much is known about him. He’s Godzilla’s father, but the trauma of the whole event and his young age made Godzilla forget almost everything about him. His wife died in childbirth and while at first he had complicated feelings towards his monstrous newborn that took his wife away, he quickly grew past that and dedicated himself to hiding and protecting his child. He was slowly mutated over time due to exposure to Godzilla and the radiation that he had to consume for energy. 

(Born Mutant) Godzilla - The Godzilla throughout the Showa and Heisei era events. The original ‘king of the mutants’. His earliest memories are fear and pain, though he doesn’t know exactly what the memory is, not realizing it’s memories of the rampage of the mutant known as ‘Gojira’, his own father. These early memories have become weak and lost due to the trauma of the event, but despite this he still had his father’s instance of staying hidden internalized and so spent years hiding from humanity. It’s not until he ran into Anguirus that he would become more widely known. While at first he had a lot of distrust and hostility towards humans for how they always tried to hunt down his kind just for existing, he did come to be more kind and protective of them, enjoying the attention he received as a kind of ‘protector’. Because of his ability to beat almost anyone, other mutants ended up flocking to him for protection and leadership. He was a bit goofy and cocky in his youth, but mellowed out a lot with age. When Mutant Island was destroyed in bomb testing, killing many mutants including his son Minilla, he lost all love and care for humanity, going back to resenting them, though now full of hatred. He no longer cared about being a ‘protector’, instead only doing what was needed to defend himself and his kind (all Heisei era enemies either attacked him or his son).

(Born Mutant) Minilla - Godzilla’s adopted son in the Showa era. While known for being a bit of a weak coward compared to his dad, he’s also known for being very kind and welcoming, especially to humans. In the split timeline, where he makes it to adulthood, he becomes a representative in human to mutant relations. He’s best friends with Baragon, mostly because they were the only children growing up on Mutant Island, and in the split timeline is a responsible and attentive older brother to Junior. While younger, he just kind of follows along with whatever Godzilla tells him, but as an adult he learns to stand his ground against him and the two often butt heads when it comes to decisions about the management of Mutant Island and relations with humans.  

(Born Mutant) Godzilla Junior - Godzilla’s adopted son in the Heisei era and known as Godzilla throughout the Millenium era events. As a child, much like his brother Minilla, he was noted as being very sweet, kind, and especially friendly towards humans, though for him it has to do with having developed a close relationship with a human when he was born. When he was a teenager, his dad sent him away suddenly, not giving him much explanation. This was Godzilla not wanting him to see him slowly die, though the lack of explanation left a bit of an abandonment issue, especially after being given away by the humans as a baby. His subsequent death at the hands of Destoroyah and being brought back only to find his father dead, all after humans drew them to the fight, breaks something in him. He not only loses all trust in humanity, but others period, becoming extremely defensive and aggressive towards anyone. This negative state is what leaves him open to being possessed by Gojira’s spirit, having always had a spiritual sensitivity since birth. The efforts of Leo, Baragon, and Anguirus to bring him back to himself, at the cost of Anguirus’ own life, finally calms him down enough to stop going out of his way to pick fights and start to regain some trust, finding and taking in Minya 2 years later helping even more. The event that really seems to bring him some closure and relief is when himself, Leo, and Minya go back in the past, and he has the opportunity to interact with his dad again, in the end splitting the timeline and risking his own existence by warning them of the destruction, in order to save Minilla’s life. 

You're just not a proper son of godzilla if a full grown kaiju doesn't wanna beat your child ass for some reason.

LEGENDARY (Minya)

POV: You walk in on the villains making out in a broom closet

I was trying to rework some designs and these were the only two of the four that I liked enough to straighten up.

With Anguirus, I wanted to solidy his hair shape which usually just turns into a bunch if random spikes, and brought in some of the curve we see in his horns. I also wanted to bring in a bit of a longer face shape to match his long snoot.

For Minilla, I've drawn him a lot, but I've never been fully satisfied with his design. Big thing was fixing the eyes and mouth, which are the most stand out parts of his otherwise plain design. I also wanted to make his hair a bit shorter, mostly taking away those curl bangs since I've since given those to Baragon.
