If the character is fictional, watch the show or film or book. If the series has a wikia, read it. Write down anything that can be referenced or make a pun. If you have a beat, constantly listening to it like it's ERB. Generally, Wikipedia and Google are your friends.

Also, small tip if you're a lazy researcher, use the character that you know deeply so you can at least cut down half of the research
