Gen 4 Beta Pokémon 

Evolves from: Lickitung [ β ]

An early version of Lickilicky.

Shows a completely different, more wheel-like design, which fits with how Lickitung must learn Rollout to evolve but makes less thematic sense.

Evolves from: Kricketot [ β ]

An early version of Kricketune.

Evolves into: Beta Gabite or Gabite [ β ]

An early version of Gible.

Uses a completely different, orange-and-cream design. Only the general "land shark" theming was kept for the final version. Is quadrupedal instead of bipedal.

Evolves from: Beta Gible or Gible [ β ]
Evolves into: Beta Garchomp or Garchomp [ β ]

Evolves from: Beta Gabite or Gabite [ β ]

An early version of Garchomp.

Uses a completely different, orange-and-cyan design, though much closer to the final version than its pre-evolutions.

Evolves from: Togetic [ β ]

An early version of Togekiss.

Completely different design. Its basic body shape is the same, but its overall appearance is more angular and less cute, and it lacks the blue and red highlights on its crest.

Evolves into: Beta Hippowdon or Hippowdon [ β ]

An early version of Hippopotas.

Uses a completely different, possibly placeholder design, resembling nothing more than a cartoonish baby hippo.

Evolves from: Beta Hippopotas or Hippopotas [ β ]

An early version of Hippowdon.

Uses a different, larger design, with its primary color scheme being orange and blue instead of brown/gray and black.

Evolves into: Beta Lumineon or Lumineon [ β ]

An early version of Finneon.

Both sprites use an early design that is smaller and thinner. Its blue parts are black and white, it has one head crest instead of two, and its tail more closely resembles a ribbon than butterfly wings. Its eyes are more almond-shaped and are purple instead of pink.

Evolves from: Beta Finneon or Finneon [ β ]

An early version of Lumineon.

Completely different design. Has a more dolphin-like face and tail, and lacks the blue stripes on its body. Its fins have iridescent stripes.

Evolves into: Beta Abomasnow or Abomasnow [ β ]

An early version of Snover.

Early sprites use a thinner, less stocky design with a more menacing expression. Its eyes match Abomasnow's.

Evolves from: Beta Snover or Snover [ β ]

An early version of Abomasnow.

Early sprites use a completely different design with a more humanoid body, a ruff of fur around its neck, and visible sclerae. The bits on its back appear to be embedded in its fur rather than growing out of it.

Evolves from: Yanma [ β ]

An early version of Yanmega.

Both sprites use an early design and were completely redrawn. The yellow-green shade was kept, but the darker shade became black and the orange became more red. Its wings are a solid shade of pea green instead of white with orange tips, and its legs are shorter and orange instead of black.

Does not evolve.

An early version of Rotom.

Uses a very simple design consisting of little more than a stylized electric spark with eyes and hands.

Does not evolve.

An early version of Darkrai.

Initial sprites use a different, potentially unfinished design. Instead of the red jaw-like ruff around its neck, it has a single red stripe starting from the tip of its crest and reaching down to its chest. Its shoulders are less broad, and it's a bit less gaunt.

Does not evolve.

An early version of Shaymin.

Initial sprites use a highly simplified, smaller design more clearly inspired by a hedgehog. It only has one Gracidea flower on its left ear, leaving the other exposed. Its entire body is visible in its back sprite.

Does not evolve.

An early version of Arceus.

Uses a very crude, possibly placeholder design, depicting a cloudy gray figure with orange circular eyes. Only the goat-like silhouette was kept for the final version.
