Name of the Eternal Pokémon: Rhydon-Eternal
New Type: Rock / Dragon
New Stat distribution: 95 (-10) / 88 (-42) / 90 (-30) / 130 (+85) / 50 (+5) / 81 (+40)
Signature Move: Breakthrough - Rock, Special, 135 BP, 5 PP, 100% Acc | The user takes 1/3 recoil and loses its Rock typing for the rest of the battle. Can only be used if the user is Rock-type. | Z-Move: 200 BP Continental Crush
Design/Flavor: Heralded as a mining king by those fortunate enough to find its elusive red body and golden horn. It frequents areas deep underground.
Competitive Analysis: High Special Attack with a recoil move allows it to make use of its otherwise useless Abilities. Hits like a truck with Breakthrough (especially if it has Reckless or a Lightning Rod boost), even though it can only use the move once. Also has strong coverage in Dragon Pulse and Earth Power for use after the move. However, it is rather slow and frail, requiring the use of Rock Polish for offensive prowess.
Name of the Eternal Pokémon: Lairon-Eternal
New Type: Steel / Water
New Stat distribution: 80 (+20) / 80 (-10) / 115 (-25) / 80 (+30) / 145 (+95) / 29 (-11)
Signature Move: Mineral Bath - Water, Other, 10 PP | If there are entry hazards on the user's side of the field, the user recovers 2/3 HP, and the hazards are removed. Otherwise, the user simply recovers 1/2 HP. | Z-Effect: +1 Defense
Design/Flavor: Having received the blessing of an enchanted hot spring, this Lairon has become cyan with brown plating. It enjoys cleaning filth from bodies of water.
Competitive Analysis: Bulky thang with a move that simultaneously recovers HP and provides hazard removal utility. It's a bit lacking on the offensive front, though, only having Water Pulse for Water STAB and only physical Steel STAB...and the stat distribution doesn't help its cause. Ah, well. Metal Burst.
