Name of the Eternal Pokémon: Wooper-Eternal
New Type: Ground/Fire
New Stat distribution: 55 / 55 (+10) / 45 / 105 (+80) / 55 (+30) / 114 (+99) | 429 BST
Signature Move: Axolotl Flare - Fire, Special, 80 BP, 15 PP, 100% Acc | Deals 3* damage in rain. | Z-Move: 160 BP Inferno Overdrive
Design/Flavor: One Wooper traveled alone from the Ruins of Alph all the way to the top of Bell Tower. There, Ho-Oh granted it a blessing that made its body glow every color at once, in addition to turning its rami white and its belly markings black. Since then, its body has been capable of producing a heat surpassing the coolness of any rain.
Competitive Analysis: Sports perfect coverage in dual STAB and Ice Beam. Can use Acid Spray to great effect, or check Ferrothorn if used on a rain team.
Name of the Eternal Pokémon: Marshtomp-Eternal
New Type: Water/Flying
New Stat distribution: 89 (+19) / 85 / 60 (-10) / 90 (+30) / 110 (+40) / 100 (+50) | 534 BST
Signature Move: Creepy Stare - Flying, Special, 70 BP, 10 PP, 95% Acc | Has a 25% chance to lower one of the target's main five stats (basically 5% for each). | Z-Move: 140 BP Supersonic Skystrike
Design/Flavor: A motley crew of Hoenn scientists found appeal in the stare of a particular Marshtomp and had the idea to preserve it for years to come. Whatever means they used (not even they can say), it ended up making the Marshtomp have a completely black body with unchanged eyes, along with granting it the power to fly with its dorsal fins.
Competitive Analysis: Stealth Rock setter and potential Z-Refresh user with effective coverage in Scald and Creepy Stare. Can potentially go mixed with Work Up.
Name of the Eternal Pokémon: Barboach-Eternal
New Type: Ground/Psychic
New Stat distribution: 50 / 38 (-10) / 75 (+32) / 125 (+69) / 77 (+36) / 102 (+42) | 467 BST
Signature Move: Luscious Lure - Psychic, Other, 5 PP | Priority +4. For the duration of the turn, the user evades all moves with finite accuracy. If the user survives next turn, then opposing Dark-types are rendered prone to Psychic-type attacks. Fails if used twice in a row. | Z-Move: Speed +1
Design/Flavor: From the lake of Paniola Town, a Barboach left its kin and flopped its way south all the way to the ocean of Heahea City, whence it made its way to Akala Outskirts and continued flopping until it got to the Ruins of Life. There, the guardian deity Tapu Lele blessed it, making its body white with a pink nose and fins. Its body additionally can glow with an irresistible and divine allure yet disappear in a flash like a quantum particle.
Competitive Analysis: Potent special attacker that actually has a use for Future Sight. Alongside its STABs, it sports adequate coverage moves in Ice Beam and Scald.
Name of the Eternal Pokémon: Palpitoad-Eternal
New Type: Water/Normal
New Stat distribution: 80 (+5) / 79 (+14) / 95 (+40) / 80 (+15) / 105 (+50) / 69 | 508 BST
Signature Move: Good Vibrations - Normal, Other, 10 PP | Clears entry hazards from the user's side, and removes status conditions from the user's party. Sound-based. | Z-Move: Fully heals user
Design/Flavor: In a turn of pure whimsy, Meloetta appeared to a Palpitoad and taught it special singing techniques to soothe its soul and those of others. The Palpitoad honed the techniques to mastery and even took an appearance inspired by its master: white belly, green stripes, and black hide.
Competitive Analysis: Vaguely like Tranquill-E, except it doesn't clear its own hazards or screens and can even set up Stealth Rock itself. It's also Normal/Water, a typing shared only with Bibarel and Taillow-E so far. If running Rest, it can prove viable on a rain team.
