Taichi was and always will be the Face of Digimon, Daisuke and Takato are somehow a resemble of Taichi, Agumon line is the Symbol of Digimon, Wargreymon is the Peak of Digimon coll designs. Dukemon took the Spotlight away from Wargreymon then we got Omegamon which is a Wargreymon and Metalgarurumon combined that made Dukemon out of the spotlight again.

Adventure 01 is always the best and always the reference for Digimon hands down.

Series wise, Final villain Apocalymon (01) Vs Red Rubbish Reaper thing (tamers) WTH is even that or had to do with Digimon....
