My custom titan is an armoured titan that ended up being forced to take on the power of a colossal titan as well, he was given a nickname by his hometown when he first transformed, he was called the "Dark Angel". No one knows that he is the dark angel, all they know is that he barely appears, unless absolutely necessary, and he protects as many people as possible. Unlike the armoured titan Reiner from Attack On Titans, he doesn't need to ever open his titan mouth to cool down after being attacked, he just needs to release colossal titan heat from body, which of course uses muscle power and that makes him unable to move while cooling down.
