This page is about elements in the Battle Network and Star Force series. For the Zero and ZX series, see here.

In the Mega Man Battle Network and Mega Man Star Force series and the game Rockman Xover, there is a set of Elements that are attached to Battle Chips, Battle Cards, Battle Memories, bosses, enemies, and transformations.

History

There are five basic Elements, known as Attributes (属性, zokusei) in Japan, introduced in the first Mega Man Battle Network game: Fire, Aqua, Elec, Wood, and no element. If a virus element is weak against a chip used, the virus will take twice damage. They would also gain territorial advantages on certain panels. The first two Mega Man Star Force series and Rockman Xover also use the five basic elements.

The element cycle is not applied strictly to characters with that characteristic, but rather only applied as a weakness to them (e.g. ToadMan is a Aqua element Navi but he can use Elec attacks, DarkMech is weak to a Cursor but it doesn't use Break attacks).

In Mega Man Battle Network 4 and 5, the system's name was reformatted into Types^[1], known as Systems (系統, keitō, can also mean "family line")^[2] in Japan. This was done as 9 new types are introduced and the Double Soul ability requires the sacrifice of a Battle Chip of the same element or type to be used. The 4 elements are now categorized as types. The 9 new types aren't strong or weak against other types.

In Mega Man Battle Network 6, there was another change due to the Cross System. In addition to the 4 traditional element weakness cycle, there is now a 4 type weakness cycle consisting of Sword, Wind, Cursor, and Break. Obstacle and Plus are still present in Battle Chip icons, but they do not inflict extra damage. There are a number of rules set upon certain attacks due to this new type implementation:

• Not all attacks that pierce guards are Break type.
• Certain chips like Yo-Yo (None and Sword) and ElecSword (Elec and Sword) have an element and type but are not indicated on the chip's info page. They are Sword chips as well, but will not be boosted by Slash Cross' attack boost.

In the first two games Mega Man Star Force series, only the elemental types is shown, but type properties are on a number of attacks. But in Mega Man Star Force 3, the Sword, Wind and, Break type icons return due to the Noise Change system. Unlike Battle Network 6, a Battle Card can have both elements and types and up to three icons (an element and up to two types) will be listed on its info page. Also, all guard pierce attacks are considered Break-type attacks.

• Star Force 3 has a created a distinction between a form's body and their weakness. Noting that forms can have a non-elemental body but still have an elemental or type weakness.

Elemental Attributes

None

The None ^[1] (無, Mu) element (Non-elemental in the Mega Man Star Force series) has no weaknesses or strengths. Also known as Null,^[3] Non-element,^[4] Elementless,^[5] and No Attribute.^[6]

Non-element attacks are neither vulnerable nor advantageous in battles against foes of a particular element. However, they are usually supported by the most number of forms, even if they're aligned with other elements.

Fire

The Fire (炎, Honō) element is strong against Wood element, and weak against Aqua element. Also known as Flame.^[7] Fire attacks tend to inflict large amounts of damage in one hit, which makes them extremely useful when combined with the double damage bonus to enemies on Grass Panels. However, these chips have a tendency to cause invisible frames.

Abilities

• If a target is standing on a Grass Panel, Fire attacks do double damage on the target, while also burning away affected Grass Panel(s). This stacks with the damage multiplier when a Fire attack hits a Wood enemy.
• In Mega Man Battle Network 2 to 5, Fire element Navis and viruses are unaffected by Lava Panels.
• In Mega Man Battle Network 5, Sea panels deal steady damage to Fire-types.

Aqua

The Aqua (水, Mizu) element is strong against the Fire element, and weak against Elec element. Also known as Water.^[4] Aqua attacks tend to be balanced, with a mix of status-inducing, multi-hitting, or powerful single hits. Starting in BN6, Aqua attacks are being able to induce Freeze or Bubble status, Aqua attacks have shifted to being used to support Breaking and Elec attacks which deal double damage to enemies in said status effects.

Abilities

• Starting in Battle Network 3, Aqua element Navi/virus will not slide on ice panels.
• In Mega Man Battle Network 5, Sea panels hide certain Aqua element characters, rendering them immune to all attacks, except attacks that have Elec element or hit panels underground.
• In Mega Man Battle Network 6 and the Mega Man Star Force series, certain Aqua attack will bubble the enemy. While bubbled, an Elec element attack will do double damage to them.
• In Mega Man Battle Network 6 and the Mega Man Star Force series, attacking an enemy standing on an Ice Panel with an Aqua attack will consume the Ice Panel and freeze them. While frozen, a guard pierce attack will do double damage to them.

Elec

The Elec (電気, Denki) element is strong against Aqua element, and weak against Wood element. Also known as Electric,^[8] and Electricity.^[6] Elec attacks favor inducing status effects over anything else, at the cost of raw power. Some will be able to inflict paralysis, which will allow for otherwise clumsy chips to be aimed better, while also allowing for an immediate follow-up attack.

Abilities

• In Battle Network 2 to 4, When a Navi/virus is standing on an Ice panel, an Elec element attack will do double damage to them. This property is completely gone in later games.
• In Battle Chip Challenge, When a Navi is standing on an Aluminum panel, an Elec element attack will do double damage to them.
• In Battle Network 5, When a Navi is standing on a Sea panel, an Elec element attack will do double damage to them.
• In Battle Network 6, if the enemy is encased in a bubble, Elec attacks will do double damage to them.

Wood

The Wood (木, Ki) element is strong against Elec element, and weak against Fire element. Many Wood attacks are notable for not causing invisible frames. This means that after such an attack connects, the enemy is still vulnerable to getting hit again, allowing for many attacks to be made in succession.

Abilities

• When a Wood element Navi/virus stands on a Grass panel, they will regain HP.

Other Types

Sword

See also: Sword (Battle Chip) and Sword (Battle Card)

Sword (ソード, Sōdo) chips have been part of the series from the very beginning but did not become a type until Mega Man Battle Network 4. It would retain its type status in Mega Man Battle Network 6, being part of a new type cycle, where it became strong against Wind type and weak against Break type. This element is also present in Mega Man Star Force 3.

Most Sword attacks tend to be swift and strong, but lack range. Sword attacks are the only ones capable of hitting shadowy viruses such as Shadows and Nightmares. It's also a heavily used as a type, assigned to chips such as Yo-Yo and TomahawkMan.

Recovery

See also: Recovery

The Recovery (リカバリー, Rikabarī) chips are main stays of the series, but is only a type in Mega Man Battle Network 4, 5, and Rockman.EXE 4.5 Real Operation. Recovery chips tend to lack offensive capability, instead focusing entirely on restoring one's own HP or providing support while in a pinch.

Plus

The Plus ^[1] (数値付加, Sūchi Fuka) chips, denoted with +/-, are another of the series mainstays that became a type starting Mega Man Battle Network 4. Also known as Bonus Point ^[4] and Add Numbers.^[9] Plus is support type, designed to raise the attack of one's own chips or Buster. One of this type's most common chips is the Atk+10 chip, which is always included in every starting folder.

Panel Destruction

The Panel Destruction (地形破壊, Chikei Hakai, "Terrain Destruction") type was only present in Mega Man Battle Network 4. Also known as Earth Shattering.^[9] These form of chips are designed to crack or break panels on the field, in order to deprive the enemy of any territorial advantages caused by panel types or to control their movement space. Metal panels cannot be cracked.

Invisible

The Invisible (インビジブル, Inbijiburu) chips are main stays of the series, but is only a type in Mega Man Battle Network 4, 5, and Rockman.EXE 4.5 Real Operation. These kinds of chips make it harder for enemies to hit the user, usually by providing some form of invisibility.

Obstacle

The Obstacle ^[1] (召喚, Shōkan, "Summon") type was added in Mega Man Battle Network 4. Also known as Summon ^[4] and Ornament.^[9] Obstacle chips summon obstacles, most often immediately in front of MegaMan. They will have an HP that must be reduced to be destroyed, but guard piercing attacks will automatically destroy them. Obstacle-related transformations always have the capability of converting obstacles on the field into a means of offense.

Wind

The Wind (風かゼ, Kaze) element was added in Mega Man Battle Network 4. It was retained in Mega Man Battle Network 6 for the new Cross system, becoming strong against Cursor type and weak against Sword type. This type is also present in Mega Man Star Force 3, although none of MegaMan's forms is weak to it.

Wind attacks focus on shifting the positions of enemies and obstacles. In Mega Man Battle Network 6 and the Mega Man Star Force series, Wind attacks are able blow away Barriers and Auras regardless of their strength.

Break

The Break (ブレイク, Bureiku) type was added in Mega Man Battle Network 4. This type is also present in Mega Man Star Force 3. Also known as Breaker.^[5] Break attacks all have the ability to damage guarded enemies. In Mega Man Battle Network 6 and Mega Man Star Force series, Break attacks also cause double damage to any frozen enemies in BN6.

Cursor

The Cursor (カーソル, Kāsoru) type was added in Mega Man Battle Network 5. In Mega Man Battle Network 6, it became part of the new type cycle, where the Navis and viruses of this element became strong against Break type and weak against Wind type.

Cursor chips focuses on attacks that having homing or targeting abilities. In Mega Man Battle Network 6, they can destroy ???? traps (such as AntiDmg and ElemTrap) and damage the target at the same time.

Battle Chips

Battle Chips related to elements.

• Anti Fire (カキゲンキン, Kakigenkin in Japan, a word used for warnings of flammability), Anti Water (ダイコウズイ, Daikouzui in Japan, "Deluge"), Anti Elec (ヒライシン, Hiraishin, "Lightning Rod"), and Anti Wood (マヨイノモリ, Mayoi no Mori, "Lost Woods") are four Battle Chips that can counter attacks from the specific element.
  • In Mega Man Battle Network 6 they were consolidated into Element Trap (エレメントラップ, Erementorappu, "Elementrap" or "Element Wrap" in Japan),which can counter any of the four basic elements.
  • Anti Sword (シラハドリ, Shirahadori in Japan) is a Battle Chip that counters attacks with the Sword property, which includes all Sword element attacks.
  • Anti Recovery (バッドメディスン, Bad Medicine) is a Battle Chip that reverses healing, which most Recovery element Chips provide.
• Fire +40 (ファイア＋４０), Aqua +40 (アクア＋４０), Elec +40 (エレキ＋４０), and Wood +40 (ウッド＋４０) are Battle Chips from Mega Man Battle Network 2 that increase the attack power of a specific element Battle Chip by 40. In Mega Man Battle Network 3 their bonus was reduced to +30 (＋３０).
• In Rockman.EXE 4.5 Real Operation a Mega Chip series was made: Fire Plus (ファイアプラス, Faia Purasu), Thunder Plus (サンダープラス, Sandā Purasu), Aqua Power (アクアパワー, Akua Pawā), and Wood Power (ウッドパワー, Uddo Pawā). They're similar to the earlier Element+ chips but must be used first and provides more effects. Fire Plus create a Grass Stage upon use, and Thunder Plus makes the Elec chip paralyze. Aqua Power and Wood Power don't provide additional effect but provides a x2 damage boost.

Other games

• Mega Man Zero and Mega Man ZX series have a simpler element system consisting of Flame, Thunder, and Ice.
• Mega Man X: Command Mission has a system similar to the Mega Man Zero and ZX series, with Thunder being strong against Water, Water against Fire, and Fire against Thunder. Besides these three, the game has Shot and Combat attributes that are taken into account for some contents.
• Rockman Strategy uses the four classical elements: Fire, Wind, Soil (Earth), and Water.

Trivia

• In the English games, when addressing elements, Battle Network usually writes it as "element-based", while Star Force writes it as "element-elemental". Example: "Fire-based chip" and "Fire-Elemental card". In the English Battle Network 4, a distinction was made with "-based" for elements and "-type" for types.
• Mega Man Battle Network 3, 4, and 6, almost had all of their Wood Battle Chips and attacks not cause invisible frames, but they were always one or two chips short of it all having that property. In the Mega Man Star Force series, all singular element Wood attacks MegaMan performs (except for Star Force's Elemental Cyclone) do not cause invisible frames.
• In Mega Man Battle Network 6, the Obstacle and Plus types remain even though none of the forms use them for abilities. They likely kept it so they wouldn't have to make it None element, where it then can be used for Beast Out's special attack chip charges.
