Първоначално League of Legends е трябвало да се достави с 20 героя, но Riot Games, разработчикът на MOBA, в крайна сметка удвои този брой, което доведе до пълното пускане на играта в Северна Америка на 27 октомври 2009 г.
Към 28 септември 2021 г. – повече от 10 години по-късно – този брой се е увеличил четири пъти, като нараства до цели 157 героя. Последният в непрекъснато нарастващия списък на шампионите е Vex, The Gloomist, тъмен и раздразнен йорд.
