It's Hard To Fight What You Can't See. It's been almost a month since Triboy's battle with R.D. and ever since he obtained a new move he calls the beam, he has been doing his very best to master it. So far he hasn't had much luck and it requires an immense amount of energy to perform. A new threat shows up after having disappeared for more than two centuries. It's known as the worst threat that's existed. Whatever it is has caused destruction not just in one city or country, but all over the world. People have feared it for a long time and could never figure out what it is exactly. Triboy learns about it and struggles to find out how to fight something he can't see or touch. He, along with the rest of humanity, is afraid of this terrifying paranormal anomaly. He must find out not only how to fight it, but how to defeat it. Especially since it's one of the things he fears most.
