I'm fine with you defeating Devimon just by punching him, but logically speaking you wouldn't get the vaccine advantage. If Gigan had been built to defeat Digimon, maybe, but Gigan's creators aren't even aware digimon are a thing.

About that... His original creators? No idea. Current masters? Heard of it, took a look inside the Digiworld and wants to do SCIENCE and RESEARCH on the inhabitants without drawing the attention and ire of the Lawmen (The Royal Knights), to little success and was only able to get basic but relatively useful data and information through remote viewing. Pretty much like using nature documentaries as basis for one's own research.

Also, if [i]Humans[/i] were able to come up with programs against/for Digimon and know quite a few things about them, even those who were initially unaware of their existence; what's stopping an incredibly advanced alien race that can trek the Multiversal Sea and unlocked the secrets of FTL travel from doing the same?
