In the Digimon Adventure franchise, Episode 16 of both the original series and the 2020 reboot represent major turning points.
Because Tai’s heart is filled with pride and force rather than true courage, Greymon undergoes a Dark Digivolution into SkullGreymon .
SkullGreymon is an mindless, rampaging skeletal monster that destroys everything in sight—including Etemon’s tower and even Tai’s friends. Eventually, he runs out of energy and reverts to Koromon, leaving Tai devastated and regretful for his recklessness.
Believing that danger and energy are the keys to evolution, Tai stuffs Agumon with food and then intentionally puts himself in harm's way to trigger a transformation.
While wandering the desert, the DigiDestined are lured into a Roman-style colosseum by Etemon. Tai, having recently acquired his Crest of Courage, becomes obsessed with forcing Greymon to evolve to the "Ultimate" level to defeat Etemon.
This episode is legendary for introducing "Dark Digivolution" and serves as a major lesson in leadership and pressure.
Joe finds his Crest of Reliability hidden under a soccer goal in the colosseum.
