The Flash Season 3: 10 Things You Need To Know About Kid Flash
5. His Powers Were Killing Him
Under the Kid Flash guise, Wally West was
living the dream of many. Not only was he under the wing of his hero, he also
had his own superpowers to play with. All was not entirely well for Kid Flash, though.
After Wally’s d*ckish behaviour as a Teen Titan resulted in many questioning what his problem was, Barry Allen decided to take his protégé for a professional examination. It was here that the bombshell was dropped that Wally West’s superspeed was actually killing him.
Each time that Wally would use his powers, not only was he put in great pain, he was actually ageing as a result. So extreme was the problem, it meant that his superspeed was slowly killing him each time he’d unleash his abilities.
With seemingly no other option, it was at this point that Wally actually gave up the Kid Flash mantle. In fact, he gave up the hero game full stop, hanging up his tights and retiring from the business.
