Pokédex entries

Slowbro

Red Blue	The SHELLDER that is latched onto SLOWPOKE’s tail is said to feed on the host’s left over scraps.
Yellow	Lives lazily by the sea. If the SHELLDER on its tail comes off, it becomes a SLOWPOKE again.
Gold	If the tail-biting SHELLDER is thrown off in a harsh battle, it reverts to being an ordinary SLOWPOKE.
Silver	Naturally dull to begin with, it lost its ability to feel pain due to SHELLDER’s seeping poison.
Crystal	An attached SHELLDER won’t let go because of the tasty flavor that oozes out of its tail.
Ruby Sapphire	SLOWBRO’s tail has a SHELLDER firmly attached with a bite. As a result, the tail can’t be used for fishing anymore. This causes SLOWBRO to grudgingly swim and catch prey instead.
FireRed	When a SLOWPOKE went hunting in the sea, its tail was bitten by a SHELLDER. That made it evolve into SLOWBRO.
LeafGreen	The SHELLDER that latches onto SLOWPOKE’s tail is said to feed on the host’s leftover scraps.
Emerald	Its tail has a SHELLDER firmly attached with a bite. As a result, the tail can’t be used for fishing anymore. This forces it to reluctantly swim and catch prey.
Diamond Pearl Platinum	Though usually dim witted, it seems to become inspired if the SHELLDER on its tail bites down.
HeartGold	If the tail-biting SHELLDER is thrown off in a harsh battle, it reverts to being an ordinary SLOWPOKE.
SoulSilver	Naturally dull to begin with, it lost its ability to feel pain due to SHELLDER’s seeping poison.
Black White Black 2 White 2	Though usually dim witted, it seems to become inspired if the Shellder on its tail bites down.
X	An attached Shellder won’t let go because of the tasty flavor that oozes out of its tail.
Y	When a Slowpoke went hunting in the sea, its tail was bitten by a Shellder. That made it evolve into Slowbro.
Omega Ruby Alpha Sapphire	Slowbro’s tail has a Shellder firmly attached with a bite. As a result, the tail can’t be used for fishing anymore. This causes Slowbro to grudgingly swim and catch prey instead.
Sun	It spaces out while gazing at the sea. With Shellder’s poison flowing through its body, it becomes even spacier.
Moon	Whenever Shellder bites down hard on its tail, it gives Slowbro a flash of inspiration...which it forgets a moment later.
Ultra Sun	Spacing out is basically all it does. It turns back into Slowpoke if its tail, along with Shellder, breaks off.
Ultra Moon	Shellder, in its greed to suck out more and more sweetness from Slowbro’s tail, has metamorphosed into a spiral-shaped shell.
Let's Go Pikachu Let's Go Eevee	Lives lazily by the sea. If the Shellder on its tail comes off, it becomes a Slowpoke again.
Sword	Slowpoke became Slowbro when a Shellder bit on to its tail. Sweet flavors seeping from the tail make the Shellder feel as if its life is a dream.
Shield	Being bitten by a Shellder shocked this Pokémon into standing on two legs. If the Shellder lets go, it seems Slowbro will turn back into a Slowpoke.
Brilliant Diamond Shining Pearl	Though usually dim-witted, it seems to become inspired if the Shellder on its tail bites down.
Scarlet	When a Slowpoke went hunting in the sea, its tail was bitten by a Shellder. That made it evolve into Slowbro.
Violet	If the tail-biting Shellder is thrown off in a harsh battle, this Pokémon reverts to being an ordinary Slowpoke.

Mega Slowbro

Sun	All the energy from Mega Evolution poured into the Shellder on its tail, leaving Slowpoke to be swallowed whole.
Moon	When bathed in the energy of Mega Evolution, Shellder converts into impregnable armor. There is virtually no change in Slowpoke.
Ultra Sun	Tremendous energy strengthened the power of the Shellder on its tail, but it doesn’t really affect Slowpoke.
Ultra Moon	Having been swallowed whole by Shellder, Slowbro now has an iron defense. It’s pretty comfortable in there, too.
Let's Go Pikachu Let's Go Eevee	Under the influence of Shellder’s digestive fluids, Slowpoke has awakened, gaining a great deal of power—and a little motivation to boot.

Galarian Slowbro

Sword	A Shellder bite set off a chemical reaction with the spices inside Slowbro’s body, causing Slowbro to become a Poison-type Pokémon.
Shield	If this Pokémon squeezes the tongue of the Shellder biting it, the Shellder will launch a toxic liquid from the tip of its shell.
