This requires some time. First, catch a Gazimon from the BIOS Domain and a SnowGoburimon from SCSI Domain. Digivolve them into Nanimon and Hyogamon. Train then until they stop growing. DNA Digivolve them, but select the Digimon with the highest level second. You should get Gazimon. Now, catch another SnowGoburimon and Digivolve it, then continue training it until it stops growing. Then, DNA Digivolve it with either a Data or Virus champion, but make sure the strongest one is second. The result is a SnowGoburimon. Train it to Hyogamon and train the Gazimon into Nanimon. When they stop growing, DNA Digivolve again, the strongest second. The result will be Gazimon. Digivolve it to Nanimon and train Nanimon until it reaches level 21 and Digivolve it into Tekkamon. If it does not reach that level, DNA Digivolve the Nanimon with another Hyogamon, strongest second, and train the newborn Gazimon. Once you get Tekkamon, keep training it until it stops growing. It should now know a large selection of different attacks. To make it better, DNA Digivolve it with another ultimate (Data or Virus) that result is Nanimon, which you then train to Tekkamon.
