Koraidon
Best Partners 2026
Koraidon's Orichalcum Pulse auto-sets Sun, powering Protosynthesis teammates and Fire attackers simultaneously. The six core partners below cover S-tier must-runs and A-tier situational picks, with a full breakdown of each synergy mechanism.
Core Partner Rankings
Koraidon's Orichalcum Pulse sets Sun automatically; Flutter Mane's Protosynthesis triggers in Sun to boost its highest stat (Sp.Atk) by 1.3× with no item cost. Flutter Mane is immune to Fake Out and Normal moves, covering Koraidon's weaknesses with near-zero overlap. Moonblast spread also pressures Dragon and Fighting threats that target Koraidon.
Fake Out gives Koraidon a free setup turn; Incineroar's Flare Blitz gains Sun's 1.5× boost as a bonus. Parting Shot lets Intimidate cycle by re-triggering on every switch, capping the opponent's physical offense across the entire game. Standard on virtually every top Koraidon team.
Beads of Ruin lowers all non-Chi-Yu Sp.Def by 25%. Sun boosts Fire moves by a further 1.5×. Stacked, Chi-Yu's Fire output treats opponents' Sp.Def as roughly 56% of its real value — almost nothing survives. The two effects together without item cost create unmatched special Fire pressure alongside Koraidon's physical offense.
Rage Powder redirects all opponent attacks to Amoonguss, letting Koraidon and Flutter Mane attack freely without being disrupted. Spore locks one opponent out of a turn. Grass typing is immune to spread Earthquake — Koraidon can use Earthquake without worrying about damaging Amoonguss.
Prankster Tailwind doubles the entire team's Speed — Koraidon hits 183 and Flutter Mane 267 under Tailwind, outspeeding virtually everything. Tornadus also threatens Taunt to shut down opposing setup and Tailwind. Note: Hurricane's accuracy drops to 50% in Sun, so non-attacking Tornadus builds are preferable in sun archetypes.
Sword of Ruin lowers all non-Chien-Pao Defense by 25%, directly boosting Koraidon's physical moves (Sacred Sword, Dragon Claw, Collision Course). The aura is passive and stackable with Intimidate debuffs — opponents can get down to 50% effective Defense before taking Koraidon's Sacred Sword.
Standard Sun Team Core Example
These three form the immovable sun team core. The remaining three slots typically draw from Amoonguss (speed control), Chi-Yu (Beads of Ruin), Tornadus (Tailwind), and Chien-Pao (Sword of Ruin) — pick three based on the current meta and your preferred style.
Frequently Asked Questions
Who is the best partner for Koraidon in VGC?
Flutter Mane is the top pairing — Protosynthesis boosts Sp.Atk 1.3× in Sun, and Fake Out + Normal immunity means almost zero weakness overlap with Koraidon. Incineroar is the standard second pick on virtually every top Koraidon team for Fake Out + Intimidate protection.
What are the weaknesses of Koraidon sun teams?
Primary weaknesses: ①Kyogre Primordial Sea overrides Drought instantly; ②Rayquaza Air Lock suppresses all sun effects; ③Amoonguss Rage Powder redirects partner moves; ④Fairy spread (Moonblast) hits Koraidon's Fighting type. Counter-strategies: Chien-Pao Ice Shard vs Kyogre, Tornadus Taunt vs opposing Amoonguss.
Does Koraidon team need Incineroar?
Strongly recommended but not mandatory. Without Fake Out support, Koraidon is vulnerable to turn-one disruption. If skipping Incineroar, Whimsicott's Prankster Encore offers alternative disruption, or run a pure speed-offense build with Tailwind from Tornadus.
