1. He came out from an egg, and i believe he never met his parents cause they died before he was hatched (i may be wrong here tho, take it with a grain of salt)
2. As a baby he was already super powerful. It was said that around he started waking on 2 legs he thrown a tantrum because his granny couldn't dine with him. It resulted in him freezing his castle and his servants. They had to call for Lilia to calm him down.
3. Lilia is scary when angry, so baby Malleus was prepared to face the worst, but Lilia were practicing gentle parenting and treated him kindly
Also plz look at this silhouette of Lilia from times when MalMal was a lil hatchling
People headcanoning him with long hair we're winning today
Edit: for those wondering if Mal has belly button: yes he does. Reptiles does have belly buttons, but in different form. It's more of a scar that goes along their abdomens
The emotional damage that talk between Malleus and Silver gave me cannot be measured with human knowledge.
Silver talks about how Llilia has done everything for him in these past 17 years since he found him - he raised him, fed him, taught him. And now as an adult Silver cannot repay him for all of it cause Lilia wants to leave and live alone. Malleus reply that Lilia truly raised a good son, to which Silver responds that he's not good son at all cause he cannot fulfill he's last wish - to keep a smile for their farewell.
Can we talk about it? Like, Silver, who we know from being the calm and collected character, started bawling in front of his older brother about being scared of loosing his father, while he remains powerless. This scene gave him so much more depth. And as a person with older parents who might be gone any day now it hits too close to home.
Also hearing his voice actor, Shimazaki Nobunaga, who I usually hear voice mostly calm characters (like Silver and Kazuha from genshin impact) giving such a strong performance was a very nice change of pace, even if the topic was so devastating.
