#2 Edge could surprisingly betray Christian after their WWE Royal Rumble 2021 reunion
While Edge and Christian are mainly regarded as an iconic WWE tag team, they were fierce rivals at one point in time.
After Edge had won the King of the Ring tournament in 2001, Christian turned on his friend out of jealousy. Both of them had an excellent rivalry, and the two would only reunite several years down the road.
While Christian was the one to trigger their feud the first time around, could Edge surprise audiences and turn on his friend in modern-day WWE? Both of them had a highly-publicized reunion at the 2021 Royal Rumble, where Christian also returned to in-ring action.
It doesn't seem like Edge could turn on Captain Charisma right now (or vice versa), but it is a possibility that needs to be considered sometime later in The Rated-R Superstar's current WWE run.
Undoubtedly, if Edge and Christian were to feud again, it would be an intensely personal feud between both of them. Also, given that Edge and Christian aren't young men anymore, their feud may even lead to a 'career on the line' match down the road.
