Neophobia suddenly appeared while the Dynazenon pilots and Kaiju Eugenicists went to a water park. It started to deflate objects with its powers. Onija, Juuga and Mujina went to pick Sizumu up so he could control it. Sizumu did so and started to fight Dynazenon's components, and targeted Dynawing until Dynasoldier and Dynastriker combined to shoot at it. They eventually combined into Dynazenon and fought against Neophobia, managing to turn it upside down only for it to reveal a mouth on its underside. After a brief fight, Dynazenon changed into Dynarex and destroyed the monster, with one of its severed antennae flying toward Onija, nearly crushing him.
