As DASH was completing their seasonal tour of showing children Base Titan, the monster Metacisus showed up out of nowhere. The inter dimensional monster wrecked havoc and before DASH could fire at him Metacisus would disappear, and he soon disappeared for good. After analyzing Metacisus, DASH concluded that he came to Earth to feed on the radioactivity in microwaves, but that only increased the possibilities of where on Earth he would go. DASH had the idea to find Masayuki, a child from the tour that could predict where Metacisus was going, to help them find where the inter dimensional monster would strike next. As Toma found Masayuki he was forced to chase him, leading him to Metacisus. After Metacisus absorbed the microwaves of a cell phone tower Kaito Touma turned into Ultraman Max. Max was having trouble with so much as hitting him, but once Masayuki revealed that cell phones give away his position DASH began to hit Metacisus and soon they led Max to the inter dimensional monster. Max threw the Maxium Sword and sliced Metacisus until he exploded.
