Weaknesses

If Sento uses the Hazard Trigger for too long, it will overstimulate his nervous system and send him into a mindless rampage. However, using devices built to counter the overstimulation or having a high enough hazard level will render the weakness null.

Ranked tied for #3 of 279 in Kamen Rider by strength.
