And... there. I think that should be just about all you need for your infobox. The first section includes their physical attributes, such as age, height, and weight. When you go into edit, you can input the information for these and the picture for him along with a caption if you wish.
As for Powers and Affiliations, I placed those in the secondary section called "Other Attributes". You can input the information for these as well, but they will only show up once their information has been filled. Does this work for you? ^_^
