Yay, I was second place in two of them!
Name of the Eternal Pokémon: Gabite-Eternal
New Type: Fire / Ground
New Stat distribution: 96 (+28) / 120 (+30) / 80 (+15) / 113 (+63) / 80 (+25) / 110 (+28)
Signature Move: Cinder Assimilation - Fire, Psychical, 70 BP, 10 PP, 100 Accuracy, A Fire/Ground attack. If targets realizes a KO with this attack, it will increase users' Attack, Special Attack and Speed by 1 level: Z-Move: 140 BP Inferno Overdrive
Design/Flavor: There is a strange guardian in Wela Volcano Park. It was supposed to be an ancient Gabite who adapted to the volcanic terrain. With the time it learned how cinders can make the volcanic ground so fertile and learned to use to its own benefit in its exclussive attack. Its skin is now deep grey, like it were covered with ashes and its claws look like red hot metal.
Competitive Analysis: A mixed attacker with a excellent offensive typing and with an attack can become it in a dangerous set up sweeper if it gets a KO. Weakness to Water and a general subpar bulk will be crippling and it needs to be mexed because Earthquake and Fire Blast are its best STAB moves. It doesn't have the best moveset either, but it'll have not that much trouble to get a set up under the right circunstances
Name of the Eternal Pokémon: Zwelious-Eternal
New Type: Ghost / Dragon
New Stat distribution: 84 (+12) / 110 (+25) / 100 (+30) / 145 (+80) / 100 (+30) / 60 (+2)
Signature Move: Specter Strike - Ghost, Psychical, 100 BP, 15 PP, - , This attack never misses, 30% of chance of disabling foe's item for three turns: Z-Move: 180 BP Never-Ending Nightmare
Design/Flavor: The hostility between the two head ended really bad when one of them gave a fatal blow to the other. Now the dead head is hanging of its body and started rotten Eternal-Zwelious's body. Its body has a tune between grey and green, its fur is falling in some parts the the thin wings are now starting to fall apart
Competitive Analysis: Trick Room abuser! Its new attack is pretty spammable, and it has a very good special attack to use its wide array of special moves. It stacks weakness with Ash-Greninja, which is terrible for Trick Room archetypes and outside Trick Room it'll face some terrible troubles due to its weakness to some common types
Name of the Eternal Pokémon: Sliggoo-Eternal
New Type: Dragon / Electric
New Stat distribution: 110 (+42) / 89 (+14) / 105 (+52) / 115 (+32) / 100 (+13) / 80 (+20)
Signature Move: Magnetic Charge - Electric, Other, -, 10 PP, -, At start of the turn, the user charges itself in a really hot plasma courtain, then it heasl 50% of it max HP. If hitted during the charge phase with a contact move, the attacker will be burned (It's a mix between Beak Blast "heating" phase and a Recover move): Z-Move: Reset user's lowered stats
Design/Flavor: This Sliggoo was abandoned by its trainer in the Chargestone Cave, it had to adapt to the enverioment and as a result it learned to control the electricity in its body as a mechanism defense. Its antennaes are now charged with electricty and have small deep blue bolts at the end, its body is not yellow and its shell is now a deep blue and has a shape is more similar to the Chargestone Cave's stones
Competitive Analysis: Sliggoo-Eternal will take advantage of two things: Gooey and the terribly misused effect of Beak Blast. Punishing contact with lowering speed is bad enough, but now U-Turn abusers will have a hard time because Sliggo-Eternal can burn them, and it's also resistan x4 to Volt Switch. It also has a good plethora of resistances, has a decent moveset and it's not terribly passive, so it can be used as a bulky utility attacker.
Name of the Eternal Pokémon: Hakamo-Eternal
New Type: Dragon / Steel
New Stat distribution: 79 (+24) / 130 (+55) / 100 (+10) / 95 (+30) / 90 (+20) / 105 (+40)
Signature Move: Copper Spin - Steel, Physical, 100 BP, 15 PP, 95 Accuracy, This attack will do 50% of damage if target uses Protect, 20% of chance to bad poison the target: Z-Move: 185 BP Corkscrew Crash
Design/Flavor: Their scales are way bigger, harder and made of copper, some of them even have spikes on them, specially the recent granted scales on its back. Despite being harde, its body is way more flexible, being able to curl up and spin to attack its foe.
Competitive Analysis: Powerful set up sweeper with a barren but decent enough phsycial moveset. Its special move is also dangerous because it crushs target's Protect and it might intoxicate target (I based this effect in copper poisoning). Steel typing is not the best offensive type ever, and it's walled by thing like Skarmory. It doesn't have the best defense either
