There's a reason Deoxys has stayed relevant since Gen 3. Psychic typing and outspeeds nearly everything without investment — it checks a lot of boxes at once. Only weak to Bug, Ghost, and Dark. Known as the DNA Pokemon.
The stat bars tell the story: Attack carries everything and HP's dead weight. But this DNA Pokemon still yields 3 Attack and Sp. Atk and Speed EVs per fight on a slow 1.25M XP grind.
A POKéMON that mutated from an extraterrestrial virus exposed to a laser beam. Its body is configured for superior agility and speed.

Hard to wall, honestly. Deoxys threatens 12 types beyond its own STAB, with Normal and Ghost standing out. Pair that with Psycho Boost and Dream Eater and switchins need to think twice.

Best Locations
Deoxys is a Mythical Pokemon rated S-Tier on our tier list. At 600 BST, it hits hard. It excels as a sweeper. That 150 base Attack does the heavy lifting.
Deoxys's biggest threats include Heracross (Bug), Misdreavus (Ghost), and Houndoom (Dark), all carrying super-effective STAB moves. Deoxys's base 150 Speed lets it outpace many threats and strike first, which matters more than trying to tank hits.
Deoxys doesn't evolve. As a Mythical Pokemon, it stands on its own without an evolutionary line. It's a Psychic type with 600 BST.
Pressure is the go-to ability for Deoxys. It increases the PP cost of moves targetting the Pokémon by one. It's Deoxys's only ability.
Deoxys is a mixed attacker — base 150 Attack and 150 Sp. Atk. Fragile — can't afford to take many hits, too. But the speed tells the real story — base 150 Speed lets it outrun most of the field. Fits the sweeper role.
