At present they're added manually per their very first appearance in any medium, no need to note when they appear in a secondary medium; however, keep in mind that it should correspond to the actual date of their debut, for instance, if a game came out January of 2015, but the character wasn't added until July of 2017, then the manually added category should be "2017 Character Debuts."

Also, if you have any question on what era something is, Golden-Age is Pre-1955, Silver-Age is 1955-1969, Bronze-Age is roughly 1970-1982 and Copper-Age is roughly 1983-1991 (though the exact break is subject to debate), and anything post-1991 is Modern-Age.
