Very early days of his pro wrestling career

Doctor of Thuganomics (or as one YouTuber said, YN Cena era)

The start of his world champion era (like 2005-2007)

When the John Cena hate really started to become pronounced

Make-A-Wish Cena / SuperCena / PG Cena

CM Punk’s frenemy/main rival during the Summer of Punk

Rise of Mic Monster Cena (Bray Wyatt and AJ Styles feuds)

Part-timer era (so you jumped on at the end of his wrestling career)

Total Divas, where John Cena was a straight up menace

Switch to movies, but NOT Peacemaker (so like The Marine or Fred)

Peacemaker John Cena

(Something I missed, feel free to comment what that is)
