This could be something - or this could be nothing however in the last few issues of the Walking Dead we've been seeing glimpses of a Savior by the name of John - and the eagle eyed of you out there will no doubt have noticed he's been popping up on the covers for future issues.
To avoid any spoilers we'd encourage you to check out the Whiperer War Arc however it seems like John is set for a little bit of involvement.....
As you will see from Issue #165 (above) and Issue #166 (below) John gets 2 x cover appearances.
Whether this is the only spot we will see him on or if there is something bigger behind this only time will tell - however he's got the look of a Walking Dead antagonist about him that's for sure.
The question however is what's his first appearance. The answer to that is Issue #104.
His appearances are limited right now but he's one to keep a watch on incase there is future development for him.
