Trivia

 * It works similarly to Guts, except only for Poison. Marvel Scale and Quick Feet also work similarly for Defense and Speed respectively.
 * The ability is likely derived from Zangoose's inspiration as the mongoose, which are known for fighting snakes.
 * Flare Boost seems to be a direct counterpart to this ability. It is a signature hidden ability that is caused by a status affliction (Burn) and boosts an attacking stat by 50%
