By consuming the essence of the Digimon Tamer, you gain several boons:
*Perfect memory with infinite storage.
*Beyond genius level intellect, process and calculate faster than super computers.
*Ability to create real living, breathing Digimon by coding them into existence on a computer. You can make any official Digimon, but also completely new, original Digimon, which are 100% loyal to you, see you as a parental figure, and can freely travel between the real world and the internet. But the more powerful the Digimon you want to make, the more time it takes to properly write their program. For example, a 1 level Digimon only takes a few hours to write up. But a Mega would take YEARS to create, due to the absurd complexity of their programs. It's advised that you make lower-level Digimon, then take the time to raise and train them in the real world until they Digivolve.
*Encyclopedic knowledge of every official Digimon ever made across the franchise, including how to raise them and how to use their abilities to their fullest potential.
*Expertise in making any Digivices or similar devices seen in the anime, mangas, and video games, as well as supplemental items you may need to bring out their full potential. This includes Crests, Digimentals/ Armor Digi-E8gs, Hyper Colosseum Cards, Legendary Spirits, Digi-Memories, etc. These can be given to others for them to use, but you have the ability to shut them down remotely if they are ever used against you. You can even mix and match Digivice models if you want a specific set of features all on one device.
*Ability to generate and control Digisoul/DNA from the Data Squad/Savers anime and the NEXT manga. Even if you don't use it with a Digivice to digivolve a partner Digimon, it can greatly enhance your physical capabilities. The maximum enhancement you can use with this is anything displayed by Masaru Daimon/Marcus Damon. You can give others the ability to use Digisoul/DNA via direct physical contact, but they have to learn how to use it the old-fashioned way like the characters in the source material.
*When a Digimon you made dies, it's reborn as a Digi-Egg on the spot unless their data's absorbed by another Digimon like in Tamers, or someone uses a device on them that's designed to permanently delete them, like Akihiro Kurata in Data Squad/Savers used.
