How many wrestler's career was destroyed by john cena?

While John Cena is known for his significant impact on WWE and Wrestling as a whole, it's subjective to say how many wrestlers' careers he "destroyed." Some wrestlers have struggled to find success or prominence in the shadow of Cena's popularity, but it’s more accurate to view these dynamics as part of the competitive landscape of wrestling rather than a direct result of Cena's actions. Many wrestlers have also credited him with helping elevate their careers through feuds and storylines. Overall, the effects of Cena's career on others vary widely and are open to interpretation.
