At first, J'onn adopted the more humanoid and superheroic Martian Manhunter look to put humanity at ease, and would only revert to his natural Martian appearance when he was relaxed in private, or under significant stress that couldn't maintain the 'transformation'. But after enough time on Earth he subconsciously started to feel like the Martian Manhunter appearance everyone came to know him by reflected his true current self and that became his default natural appearance which he didn't need to consciously maintain at all.
