Kaden the Hero is an Attack Type Story Hero.
A corrupted version of him is faught at the end of Hero Temple (10-6), after which he is purified, and joins the group.
Kaden was originally a God Tier hero. As of the 1.5 update, which brought with it the release of Erina the Legendary Hero, Kaden has been bumped down a tier, due to being outclassed by her. Despite this, it is important to note he is still one of the most powerful heroes out there.
