I find it strange that some fans refuse to accept robot gods but can acknowledge the existence of robot demons. Then again, a few fans would avoid deities altogether. Anyway, because a lot of stories make use of demons, and I think maybe TF can draw from these stories to make its own - Hellboy – an infant demon is adopted and raised to be a hero struggling with his demonic heritage and potential to damn the world, no matter how hard he tries to save it. - Devilman – a hero gains a demon’s skull and uses it to become a super anti-hero - DC’s Capt Marvel faced off with the Seven Deadly Sins (demonic avatars of pride, wrath, envy, greed, gluttony, sloth and lust) - Kimetsu no Yaiba - a young boy joins a league of demon hunters to save his sister, who was attacked by demons and is gradually turning into one. - Seven Deadly Sins - a demon and angel fall in love, and are punished to be separate from each other. It’s worth noting though that Japanese culture portrays demons as anti-heroic characters who generally only follow their nature. So in a story that can allows the existence of demons, there is some great storytelling potential. It's bound to be degrees of scary and horror-themed, but the older fans may be able to endure and appreciate it. The idea of a Transformers version of Hellboy is particularly appealing IMO.
