The only way to get TM15 Hyper Beam in Pokémon Platinum is to purchase the TM from a vendor on the third floor of the Veilstone Department Store. It costs 7500 PokéDollars, and you can buy as many copies of the TM as you want.
As for the move itself:
Hyper Beam is a damage-inflicting Normal-type special move. It has an extremely high base power of 150, but forces the user to spend the next turn recharging and unable to act.
TM15 Hyper Beam Location
TM15 Hyper Beam can be acquired at any time after you first arrive in Veilstone City, by purchasing it at the Veilstone Department Store.
To locate the Department Store, first head north from the Veilstone Pokémon Center.
Then turn to the west at the houses you see.
The massive orange and pink building is the Department Store.
Use the elevator or the escalators to reach the third floor—the TM floor—and speak to the clerk behind the southwestern counter.
She will sell you TM15 Hyper Beam for 7500 PokéDollars, making it the most expensive TM in the store.
This is the only means of obtaining TM15 Hyper Beam, but it can be purchased as many times as needed.
Hyper Beam Details and Uses
Hyper Beam is a damage-dealing Normal-type special move. It has an extremely high base power, but it requires the user to rest afterwards, essentially skipping a turn.
|Hyper Beam Move Details|
|PP||5 (max. 8)|
When Hyper Beam first debuted in the Gen I Pokémon games, it was devastating – due largely to the user being able to skip the recharge turn if the target was knocked out by the attack.
This was fixed in subsequent games, and Hyper Beam is no longer as feared as it once was.
The 150 base power is still one of the highest in the game.
But since it’s spread out over two turns, it might as well have a base power of 75. Normal-type moves are also not super-effective against any Pokémon type, so there’s little strategy involved with using Hyper Beam outside of needing a sudden blast of brute force.
One notable exception is Porygon-Z with the Adaptability Ability.
Porygon-Z has an extremely high Special Attack stat. And being the same Normal-type as Hyper Beam means it will add STAB damage to Hyper Beam’s already high base power.
Adaptability further increases STAB’s 1.5x damage multiplier to 2x, bringing Hyper Beam’s base power to a stratospheric 300 – and allowing it to knock some of the strongest Pokémon in the game out in one hit.
This is especially useful against notoriously high-HP Pokémon like Blissey and Snorlax.
Miscellaneous information about Hyper Beam:
- If Hyper Beam misses, the user skips the subsequent recharge turn.
- If the user has the Truant Ability, the recharge turn will take place during the “loafing around” turn, with no further penalties.
- When used in a Pokémon Contest, Hyper Beam earns the user 2 Appeal Points, plus 3 bonus Appeal Points if the user hits max Voltage with the move.
