Great offensive stats, overall defenses that are better than most dedicated walls, and a wide movepool all make Arceus a top-notch threat in Ubers. Furthermore, Fighting Arceus has several advantages over other Arceus formes. First, Fighting Arceus lacks common weaknesses, which makes Him rather hard to take down, especially after a few Calm Mind boosts. Resistances to common attacking types in Dark, Rock, and Bug also allow Fighting Arceus to switch into attacks with relative ease. However, Fighting Arceus isn't without His cons: for example, Fighting-type STAB is not great in Ubers thanks to the popularity of Psychic-types. Nevertheless, Fighting Arceus should not be taken lightly, as He is still a threat every team should prepare for.
Like every other Arceus forme, Fighting Arceus possesses awesome base 120 stats across the board, and is blessed with a wide special movepool, including coveted moves in Calm Mind and Recover. Fighting Arceus separates itself from the pack with its uncommon typing, which gives it some oddly useful resistances and few weaknesses. All these traits come together to make Fighting Arceus one of the best users of Calm Mind in Ubers.
Judgment is its primary STAB move, and can severely dent any Pokemon who doesn't resist it after Fighting Arceus has notched up two Calm Minds. Two Calm Minds propels Fighting Arceus's naturally great Special Attack stat to a mammoth 554. Ice Beam widens Fighting Arceus's coverage, and hits several important Uber sweepers, namely Zekrom, Groudon, Rayquaza, Garchomp, and Shaymin-S, for super effective damage. Volcarona and Chandelure are the only Pokemon who resist the combination of Fighting and Ice, and fortunately, neither are seen much in Ubers play. Dark Pulse allows Fighting Arceus to hit Ghost-types, who are immune to Fighting Arceus's primary STAB, for super effective damage; it also hits the horde of Psychic-types in Ubers, especially Mewtwo, Mew, and Psychic Arceus, for super effective damage. However, Ice Beam is generally the better option because of its higher Base Power and specific coverage.Team Options & Additional Comments >>>
Fighting Arceus is an excellent Calm Mind sweeper, but it is equally adept at taking on a more supportive role. Arceus has a great support movepool, boasting access to moves such as Recover, Will-O-Wisp, and Stealth Rock. Fighting Arceus's great bulk, excellent 120 / 120 / 120 defenses, and lack of common weaknesses all help it in its role. Judgment has good neutral coverage in the Uber tier and does respectable damage even when unboosted thanks to Arceus's great base 120 Special Attack stat and STAB. Ice Beam has great coverage and is especially useful for taking out the ubiquitous Dragon-types in Ubers, most notably Rayquaza, which Fighting Arceus is an excellent check to. With Recover, Arceus can heal up during battle, increasing its overall longevity.
Toxic is the primary status move, and is chosen over Will-O-Wisp due to its ability to cripple Fighting Arceus's four greatest checks: Ho-Oh, Mewtwo, Latias, and Lugia. Will-O-Wisp also provides less general utility, as the only semi-common Steel-type that can switch into Fighting Arceus is Jirachi; physical attackers and support Pokemon such as Dialga and Ferrothorn can be smacked with a super effective STAB Judgment instead of relying on residual damage from Will-O-Wisp.Team Options & Additional Comments >>>
A Swords Dance set can be used with Brick Break, Shadow Force, and Recover as the remaining moves; Earthquake can also be run for its great neutral coverage. However, such a set is better done by Normal Arceus. Fighting Arceus can also use Cosmic Power to boost its defenses. Arceus has a huge support movepool and has no dearth of options; unfortunately, it often finds itself outclassed at many of them. For example, Arceus can set up dual screens, but is outclassed by Lugia at this job.
Checks and Counters
Ho-Oh is a great counter to Fighting Arceus thanks to its huge Special Defense and HP, as well as its useful typing: it resists Judgment and takes little damage from Ice Beam and Dark Pulse. Ho-Oh also gets Brave Bird to OHKO Fighting Arceus, and even has access to Recover or Roost to heal off any recoil damage taken. Soul Dew Latias can win the Calm Mind war thanks to the additional boost from her item and access to Psyshock, which not only bypasses Arceus's boosts, it also hits for super effective damage. Ho-Oh's legendary companion, Lugia, walls Arceus quite nicely too; it easily shrugs off Fighting Arceus's attacks, can set up Light Screen to further reduce the damage it takes, and proceed to stall out Arceus with a combination of Toxic and Roost. If Arceus tries to set up, Lugia can just blow it away with Whirlwind. If Fighting Arceus forgoes Dark Pulse for its coverage move, Wobbuffet becomes a massive pain as it can Encore Fighting Arceus into Calm Mind or Recover.
Mewtwo can outspeed Fighting Arceus; offensive variants can OHKO with Psystrike, while defensive ones can use Taunt to prevent Arceus from using Recover or setting up. Mewtwo also resists Judgment, and an unboosted Dark Pulse will only 2HKO. Shaymin-S is resistant to Judgment and can 2HKO Fighting Arceus with a speedy Air Slash, but if Fighting Arceus is lucky enough not to flinch, an Ice Beam will have Shaymin-S crying. Psychic Arceus is a good counter to Fighting Arceus; both can Calm Mind up, but the war will be won by Psychic Arceus thanks to its type advantage and access to Psyshock. Calm Mind Kyogre can defeat Fighting Arceus with its strong STAB moves and high Special bulk. Reshiram can come in on a Will-O-Wisp from the support set and 2HKO Arceus with Blue Flare. Jirachi is not OHKOed by any attack and can cripple Fighting Arceus with Thunder Wave and then take it out with Zen Headbutt or repeated Iron Heads.
