Grants the user protection for the rest of the turn and poisons any Pokémon that tries to use a contact move on it.

Baneful Bunker protects the user from all damaging moves and effects except for end of turn damage such as weather like sandstorm or major status conditions.
When Baneful Bunker blocks a contact making move, the attacker is also poisoned unless they are immune to poison.
Pokémon are immune to poison if:

• they are a Poison-type Pokémon
• they are a Steel-type Pokémon
• they have the ability Immunity
• they are behind a Substitute

A contact making multi strike move such as Arm Thrust only counts once per use.
This is also the case if the user was type-immune to the contact move.
Once blocked, the move will not activate other effects that require contact such as Rocky Helmet
Baneful Bunker has a highly increased priority meaning that it moves before most other moves.
If Baneful Bunker still goes last in the turn, it fails.
The list of unprotectable moves is the same as Protect.
Each time Baneful Bunker is successfully and consecutively used, its chances to succeed are lowered by 66.67%. This is also shared with other protection moves that only protect the user, Endure, Quick Guard and Wide Guard.
The list of unprotectable moves is the same as Protect.
Damaging Z-Moves and Max Moves do 25% of the original damage except G-Max One Blow and G-Max Rapid Flow which are not protected from.
