Why would you ever delete a character. I could understand not using this or that character . . . maybe it just wasn't selling well. Maybe she/he/it didn't fit into your current story line.BA did not delete leaked characters back then. Now they do.
But delete? Criminy, we are talking about a well drawn comic image. It's not like your executing the character or something. If you deleted a character and then later brought it back, would there be world-wide repercussions? Famine in India? Flooding? Cosmic misalignment?
