Kinda feels weird in my opinion considering he's only part time and hasn't been heel since 2003. I feel like it was only done because of the Cody Rhodes fans not wanting to accept a Rock vs Reigns match at Wrestlemania so they had to do a major shift in the storyline

Surprisingly The Rock hasn’t been a heel much in 21 years. Based on the popularity of Cody Rhodes, The Rock will have an very lengthy heel run.
