As any Dark Souls player knows Oscar is the very first person we meet in the game. He gave use the key to our cell, our Estus Flask and tells use of the legend (not Giant Dad) of the choosen undead. Most people don't know about his cut content. Oscar wasn't supposed to die at the Asylum and hollow he was instead going to be a more like Solaire were he has overworld diaoluge and helps fight enemies. He was also destined to be your opposite. Depending on your ending he would try and kill you to become the right monarch (if you wanted to become the Dark Lord then he'd want to rekindle the first flame and visa versa). It's a shame that this didn't make it to the final cut of the game, it would have added more content and a different story overall.
