Obstruct protects the user from any moves except status moves for that turn. Additionally, if Obstruct blocks an attack that would make contact with the user, the attacker's Defense stat drops by 2 stages. If Sucker Punch is used on a Pokémon that has used Obstruct, the move fails and the Pokémon's Defense does not drop. Obstruct causes the Defense stat to drop even if the user of Obstruct was immune to that contact move.
This move enables the user to protect itself from all attacks. Its chance of failing rises if it is used in succession. Direct contact harshly lowers the attacker's Defense stat.
Bold indicates a Pokémon gains STAB from this move. Italics indicates a Pokémon whose Evolution or alternate form receives STAB from this move. A dash (−) indicates a Pokémon cannot learn the move by the designated method. An empty cell indicates a Pokémon that is unavailable in that game/generation.
The user takes up a defensive posture. Using this move again will make the user leave this defensive posture. No other actions can be taken when in this defensive posture. Nullifies an attack move that targets the user while it is in this defensive posture, then the user leaves the defensive posture. If the move was a physical attack move, lowers the Defense of the opponent that used it by two stat ranks.
