Re: Robin or no Robin?
He could be used as a device to instill fear though. Imagine a scene where a criminal is already fleeing Batman, and thinks he's escaped. But in the shadows he can hear something else following, too light to be fully grown man, then laughter stalks him through the alleyways, manic, unceasing and penetrating and as his heart rate increases, beating through his ribcage he is beaten by this laughing devil dressed in ashen black, and a flaming red and yellow demon child.
Robin could work as an extension of Batman being a weird creature of the night.
