Appendix:F.E.A.R.

F.E.A.R. is a widely-known strategy used in competitive battling, often used as a last resort. A Pokémon with the ability to have the moveset below is called a F.E.A.R. Pokémon. This Pokémon is capable of defeating a full-HP opponent at virtually any level (most notably L.100) while itself is only at Lv.1 or 2. The most common Pokémon used for this strategy is a Rattata. F.E.A.R. generally stands for:

Focus Sash
Endeavor
Attack (Quick Attack)
Rattata

Alternatively, it is known to stand for "F---ing Evil Annoying Rodent".

How to use F.E.A.R.

After one of the player's Pokémon faints, the F.E.A.R. Pokémon can be sent out against an opponent's Pokémon with (preferably) full HP (though other situations will work, albeit possibly not as well). During the first turn, the F.E.A.R. Pokémon will use Endeavor, and the opponent will most likely use an offensive attack to try to defeat the F.E.A.R. Pokémon (assuming, of course, that the opponent isn't aware of this strategy). The F.E.A.R. Pokémon would indeed faint, if it were not holding the Focus Sash, which allows the user to hold on to 1 HP after a hit which would otherwise knock it out from max-HP. When the Pokémon uses Endeavor, the HP of the opponent's Pokémon will equal the HP of it's own (which is now, assuming Focus Sash triggered, equal to 1). During the following turn, the F.E.A.R. Pokémon can use Quick Attack to wipe out the remaining 1 HP of the opponent's Pokémon. Obviously, this strategy works only once per battle, seeing as Focus Sash will not work twice.

Countering F.E.A.R.

While an impressive strategy, F.E.A.R. is very widespread, making it next to useless, as many teams are able to counter it and players are aware of how it works and how to stop it from working. The following are six ways to counter the F.E.A.R. strategy:

Knowledge: The simplest strategy and perhaps the most effective. If the opponent knows the F.E.A.R. strategy, they won't attack as needed for it to work (a damaging move), or they will switch out for a Pokémon immune to it or easily able to counter it. Besides the other three counters listed here, a player could switch out after the opponent's F.E.A.R. uses Endeavor, leaving it with 1 HP and another Pokémon to sweep the F.E.A.R. However, if the F.E.A.R.-using player predicts correctly, this problem can be solved using Pursuit.
Ghost-types: As Ghost-types are immune to Normal- and Fighting-type attacks, Endeavor and Quick Attack are useless against them. It should be noted however, that a F.E.A.R. Kangaskhan with Scrappy will still be able to use Endeavor against a Ghost-type Pokémon.
A Pokémon with Quick Attack, ExtremeSpeed, Sucker Punch, Ice Shard, or other automatic, first-hit effects: If the opponent uses an increased-priority move at the same time as the F.E.A.R. Pokémon does, the large difference in level will almost always result in the opponent's Pokémon landing the hit first, leaving your opponent with little HP, but leaving the F.E.A.R. player with one Pokémon down.
A move that damages foes upon switching in (like Spikes or Stealth Rock) can cancel out the Focus Sash effect, thus causing the foe to be unable to withstand a one-hit KO. This only works if the F.E.A.R. Pokémon isn't released prior to that move.
Moves, abilities, and statuses that deal damage every turn (like Sandstorm or Burn) can cancel out Focus Sash's effect. This can also work without using a turn if a Pokémon like Tyranitar, Hippowdon, or Abomasnow activate their abilities. (Note that F.E.A.R. Phanpy are immune to Sandstorm.)
Embargo prevents the foe from using any item, in this case Focus Sash.
Leftovers return some HP to the users Pokémon, and more than likely, more than the opposing F.E.A.R. can deal with its increased-priority move.
F.E.A.R.: Ironically, a way to combat a F.E.A.R. Pokémon is having it face another F.E.A.R. Pokémon (or some other low-level Pokémon). Having roughly the same HP, both F.E.A.R.s would do little damage towards each other. It isn't, however, practical or useful to carry a F.E.A.R. Pokémon just for the sake of combating another F.E.A.R., as both Pokémon are about evenly-matched.
