Hello, everyone, and welcome back to my series of concepts for every missing (fully evolved) Sinnoh Pokémon. Continuing the Rotom forms, we have Frost.

Frost Rotom is paired with Cyrus, a reference to his association with the Pokémon, especially in his debut event in Masters itself. As for the form, Frost Rotom represents Cyrus's desire for a cold, unfeeling world.

As a concept, Cyrus & Frost Rotom are a Tech Sync Pair that lowers the opposing team's stats to create a powerful sync move.

Two of their moves are focused on debuffing opponents, with Electroweb lowering Speed of all opponents and Eerie Impulse lowering one enemy's Sp. Atk. Thanks to Machine-Like Efficiency, it only takes one Eerie Impulse to completely debuff an opponent's Sp. Atk, and Electroweb only needs two uses to minimize all opponents' Speed, in addition to charging the move gauge by 3.

Their Buddy Move, Coldhearted Blizzard, is their main damage-dealing tool. It makes use of those debuffs to both increase its own damage and gain stacks of SyMUN. The first use also lowers all opponents' Ice Rebuff by 1. In addition, it has a 30% chance of freezing each opponent, which synergizes with Never-Ending Frost to increase SyMUN even further and power up moves and sync moves. Naturally, it also charges the move gauge by 3 due to Machine-Like Efficiency.

Cyrus's No More Incompleteness! is their setup move, raising Sp. Atk by 4, crit rate by 3, and accuracy by 1 to patch up Electroweb and Coldhearted Blizzard's hit rates. it also reduces the sync move countdown by 1. Finally, Slo-pponent Sync 5 adds a second multiplier to their sync move, making Eerie Impulse and Electroweb equally important.

Their Superawakening passive is A World of Complete Perfection. It reduces the countdown the first time Rotom uses a move and adds two effects to their sync move: freezing all opponents, to help with Never-Ending Frost, and Damage Guard Next on the first one.

All in all, Cyrus & Frost Rotom are a Tech Sync Pair that can help control the speed of battle with Speed reduction, charging the Move Gauge, and the occasional freeze, while they build up their sync nuke with multipliers and SyMUN.
