Diaboramons rookie form Karamon sends Tai and Izzy a letter again. Jennai and the digi-destined digimon make contaced using Izzys computor. most of the other digidestined are busy so Agumon and Tentomon have to fight Karamon alone. Agumon and Tentomon "sneak up on" Karamon. Agumon and Tentomon digivolve to champion. Kara mon bypasses champion and jumps to ultimate. Greymon and Kabuterrymon are defaeted before fully digivolving. Infermon starts calling everone in the the world. Izzy gets a satillite uplink for the computor. Matt and T.K find a computor and send patamon and gabumon. WARGREYMON and METALGARURUMON fight DIABOROMON and are defeated. with the help of there human partners the 2 mega digimon digivlove into omnimon and stop diaboromons nuclear strikes.
