After the recent events, in spite of relative peace on File Island, your team is still wary and wants to be prepared for another possible attack. Even though you trained your team well and the experience they gained after defeating countless enemies is immense, you feel that your Digimon might not tell you how exhausted they might be.
Trying to find a solution, you scout the Digi-web for any information on how to increase the power level beyond their current state, and indeed, on some extremely obscure website you found a hint that might help you further: the X-Antibody.
Talking to the team about this mysterious element, you begin asking around via encrypted messages all over File Island's servers. And soon enough, you receive a ping:
"Hello, Tamer. I have a deal for you: I shall give you the X-Antibody Indicator which can detect the X-Antibody you're searching for, in exchange for your strongest team member. If you're not convinced, then reach these coordinates to see it for yourself of the sheer power it possesses."
This is utter madness, but clearly the source of this message must be caught and put to justice before it can harm the whole Digi-World!
After devising a sound plan, you and your team teleport to the indicated location: as thought, it's not a known place on File Island, but it looks more like an artificial platform brimming with power cables in its floor, on a parallel network. There's nothing in sight except for countless huge metal spikes, tens of meters high.
"Whoever had the power of accessing this location is no weakling... " but before a team member could finish its sentence, an extreme power surge shot up in the horizon and began a straight trajectory towards you. Then an ominous voice boomed: "I was not joking when saying that you may see it for yourself. Prepare to engage one of my greatest warriors: Nefertimon X Antibody!"
