Crests (Digimon)

Crests
In Digimon Adventure, crests were used to allow the digimon that belonged to the digidestined to digivolve into the ultimate level. They also allowed Tai and Matt to digivolve to their Mega Levels. The Crests are, Courage, Friendship, Love, Knowledge, Sincerity, Reliability, Hope, Light and Kindness. In the second series, called Digimon Adventure 02 (or zero two in Japan) the crests were put on the Digi-Eggs, which allowed the new 'ancient' Digimon to digivolve to the next Level. After Kimeramon was destroyed along with the digimon emperors base, Ken Ichijouji, who vowed to never become the digimon emperor again, got the crest of kindness after the dark spore inside of him had been deactivated.
