Well, you could have an OC that is a genius inventor who gets caught in the Joker's crosshairs. The Joker wants to use their inventions for his evil schemes, but the OC manages to escape and teams up with Young Justice. They use their tech skills to outwit the Joker at every turn. Also, an OC with the power to manipulate emotions could be interesting. They try to understand the Joker's psyche through his emotions and end up being a key figure in a plan to stop him.
One idea could be to create an OC who is a former victim of the Joker's madness and now has powers as a result. They could join the Young Justice team to seek revenge against the Joker. Another idea is an OC who is related to an existing character in the Young Justice universe and is lured into the Joker's chaotic world. For example, a relative of Robin who the Joker tries to corrupt.
