The player is challenged to make it through seven rooms, but before each one they are given a choice of three rooms to enter. In any room, one of the following eight events may occur:
Single battle: A Trainer with 3 Pokémon walks up to the player and battles.
Double battle: Two Trainers each with 1 Pokémon walk up to the player and battle.
Single battle and healing: The Single battle Trainer is more difficult than usual and the winner's Pokémon are completely healed.
No event: An NPC stands in the room but does nothing.
Status effect: A surprise attack will inflict a status on one or more of a player's Pokémon. The status includes Kirlia's burn, paralysis, poison, or sleep and Dusclops's burn or freeze.
One or two recovery: One or two of the player's Pokémon will be healed.
Full recovery: All three of the player's Pokémon will be healed.
The player may not change the order of his/her party during a challenge.
In the area where the player must pick one among the three rooms, a lady standing outside will name one room and hint at what is in that room. Each quote has two possibilities, but the first is more common than the second.

Pike Queen
The Frontier Brain of the Battle Pike is Pike Queen Lucy. She challenges Trainers who complete two passes through the pike (Silver) and 10 passes through the pike (Gold). By beating her, one is awarded with the Luck Symbol.
The Battle Pike has a battlefield with both land and water portions, allowing aquatic Pokémon, such as Lucy's Milotic, to battle effectively as well. In the Battle Pike, challengers have to defeat the Pike Queen in two consecutive Single Battles. Using his Donphan and Pikachu, Ash was able to defeat Lucy, earning the Luck Symbol, his fourth Frontier Symbol.
Pokémon used in the Battle Pike
The following is a list of Pokémon used in the Battle Pike:
Lucy's signature Pokémon is Seviper. It appeared for the first time fighting Jessie's Seviper and later battled Ash's Donphan, defeating the former and losing to the latter.
Milotic was Lucy's second choice after defeating Seviper. It was able to defeat Ash's Donphan with a single Hydro Pump. In the fight against Ash's Pikachu, Milotic managed to deal severe damage to Pikachu, but Pikachu won after using Volt Tackle in one of Milotic's Twisters.
The Battle Pike appeared in An Infinite Bond!!, where Ash battles and defeated Lucy there, just like in the anime.
In the Pokémon Adventures manga
The Battle Pike first appeared in As Luck Would Have It, Kirlia, where Emerald challenged it as his second Battle Frontier challenge during the Battle Frontier's seven-day opening ceremony. Using a team of Pokémon he had borrowed from Crystal, Emerald eventually made it to the 140th room, where Lucy was located, and begun battling against her. Although he seemed to be at a tight spot by the end of the battle, he managed to make a comeback and defeat Lucy, earning him the Luck Symbol.
After the battle, rather than exiting through the back door, Emerald chose to take the long way back through the rooms he had traveled through during his challenge. Accompanied by Todd Snap, he met Latias, who had disguised herself as one of the Battle Pike maids in order to secretly support him. Using his special mud pellets, Emerald calmed down a group of wild Pokémon that had been about to go berserk before exiting the facility, including a Dusclops, which would later start following him.
In the Pokémon Battle Frontier manga
The Battle Pike appeared in The Predestined Battle!, where Enta challenged the facility, eventually facing Lucy. His Zangoose, which he had caught shortly before entering the Batte Frontier, was full of anger, especially in the face of its natural enemy, Seviper. However, when Enta protected Zangoose from Seviper's Poison Tail, it calmed down and ended up winning the battle, earning Enta the Luck Symbol.
Trivia
A girl inside the Battle Pike says "I've completed the challenge 10 times now, but I've never had to battle a Trainer once." This information would be false, because after two straight wins and again at ten straight wins, she would have to battle Lucy. However, it should be noted that she did not state whether or not she beat the Battle Pike ten times in a row, so this might not necessarily be an error.
