Hazard Trigger

"Hazard on! (Organic Fullbottle name)! (Inorganic Fullbottle name)! Super Best Match! Don Den Kan! Don Den Kan! Gata Gata Gotton! Zuttan Zutan! Uncontrol Switch! Black Hazard! Yabei!" - The transformation sound into any Hazard form.

Hazard Trigger (ハザード トリガー Hazādo Torigā) is according to Soichi Isurugi that it is the forbidden item from the devil's scientist Takumi Katsuragi. Similar to Sclash Driver, it has a side effect, in which prolonged use will make the user lose their sense of self. When used on a Smash, it will die once defeated. It is able to upgrade Best Matches in Hazard forms and upgrade Smashes into Hazard Smash.
The device was already created by Katsuragi and was kept away due to how dangerous it is. Blood Stalk was able to get his hands on it and uses it to upgrade the Hokuto Three Crows. He later gave it to Sento, who uses it to upgrade his Best Matches into its Hazard forms.
