4) Dream Of The Endless
Neil Gaiman’s seminal The Sandman comic series created a unique mythology that took place in the outer realms of the DC universe and starred a character named Dream AKA Morpheus AKA the Sandman.
One of the seven family members of the Endless – personifications of universal concepts – the Lord of Dreams has a fascinating character arc over the 75 issue run. Due to being trapped on Earth, the Sandman learns human emotions such as compassion and mercy. He’s always aloof and removed – and occasionally cruel – but he becomes more of a hero as time goes on, facing Lucifer himself, various demons and his cruel sister Desire. Nearly twenty years after the end of the series, the character later reappeared in the limited prequel series The Sandman: Overture.
Also, a shout out is in order to Dream’s other sister, Death of the Endless AKA the Grim Reaper. Presented as a perky goth girl, Death is the breakout character of The Sandman comics and has even occasionally appeared in the regular DC universe.
