Anime appearances

"Timelord", known as "Time Machine God" (かいしん, Jikaishin) in Japan, is an archetype of Fairy-Type Monster Cards used by Z-one.

According to Z-one, there are 10 of them, in which he refers to them as aspects to the Almighty God, the 11th member, "Sephylon, the Ultimate Timelord".

"Necrolancer the Timelord" is not a "Timelord" card, because it does not have 「かいしん」 in its Japanese name.


5Dx151 The Life Tree

The Tree of Life and the Timelords

The first 10 "Timelords" are based on the 10 attributes or emanations of the Tree of Life, the mystic symbol used in the Kabbalah, known as the Sefirot. The 11th member, "Sephylon, the Ultimate Timelord", is named after the Sefirot itself (also spelled Sephirot). The "Timelords" are depicted as machines with the faces of angels on screens in their chests. Their bodies are metal suits of armor manipulated by the angel they show.

The first 10 "Timelords" each reflect a Sefirah, as well as an archangel. "Sephylon" reflects the mystical state where all 10 Sefirot become one, Da'at, and God.

Timelord Lineart


The "Timelords" are Level 10 Fairy-Type monsters of various Attributes, except DARK. The majority have 0 ATK and 0 DEF, except for the last two ("Sandaion" and "Sephylon").

In the anime, the first 10 "Timelords" (excluding "Sephylon") all share the following effects:

"Negate this card's destruction by battle or by card effects. You can reduce any Battle Damage a player takes from battles involving this face-up Attack Position card to 0. [...] While you control this face-up card, you cannot Summon monsters. During your Standby Phase, return this card to the Deck.

In Yu-Gi-Oh! 5D's Tag Force 6 and in the OCG/TCG, the shared effects are instead:

"Cannot be Special Summoned from the Deck. If you control no monsters, you can Normal Summon this card without Tributing. Cannot be destroyed by battle or card effects. You take no battle damage from attacks involving this [Attack Position] card. [...] During your Standby Phase: Shuffle this card into the Deck."

In Tag Force 6, the first 10 "Timelords" provide battle damage immunity only while they are in Attack Position; in the OCG/TCG, this limitation only applies to "Metaion", the first one.

In addition to the above, each of the first 10 "Timelords" has a unique effect of their own. In the anime, this effect activates right after they battle; outside of the anime, the effect instead activates at the end of the Battle Phase in which they battle (except for "Raphion", whose effect activates at the end of the Damage Step). These effects all involve returning one or more cards back to the hand or Deck, raising the player's LP, and/or lowering the opponent's LP (aesthetically, the cards and the player's LP are "sent back in time" to where they used to be, or the opponent's LP may be "sent forward in time"). "Lazion" and "Zaphion" also have an additional effect outside of the Battle Phase.

When the "Timelords" were first made playable in Tag Force 6, many of these unique effects were toned down; some effects were further changed when released in the OCG/TCG.

A full list of unique effects follows:

  • "Metaion" returns all monsters the opponent controls to the hand, and inflicts 300 damage to the opponent for each monster. In Tag Force 6 and the OCG/TCG, it returns all other monsters on the field to the hand (instead of only the opponent's) and inflicts 300 damage to the opponent for each.
  • "Lazion" shuffles all monsters the opponent controls and all cards in the opponent's Graveyard into the Deck; in addition, it inflicts 1000 damage to the opponent whenever they draw during the Draw Phase. In Tag Force 6, it shuffles only the opponent's Graveyard into the Deck without affecting their field; also, the additional effect has no Draw Phase restriction, but the damage is reduced to 500. In the OCG/TCG, the damage is 1000 like in the anime, but is once per turn.
  • "Zaphion" shuffles all Spell and Trap Cards the opponent controls into the Deck; in addition, it allows its controller to draw until they have 5 cards in their hand whenever it leaves the field, including by its own effect. In Tag Force 6, this additional draw effect was removed. In the OCG/TCG, it allows its owner to draw 1 card if it is sent from the field to the Graveyard.
  • "Sadion" makes its controller's LP become 4000, if their LP is lower than 4000.
  • "Kamion" shuffles all monsters the opponent controls back into the Deck, then inflicts 500 damage for each one. In Tag Force 6, it targets and shuffles 1 opponent's monster into the Deck, then inflicts 500 damage. In the OCG/TCG, it shuffles back 1 opponent's card (of any card type) and inflicts 500 damage, also neither player can activate cards or effects in response.
  • "Michion" inflicts effect damage to the opponent equal to half their LP. In Tag Force 6, it directly halves the opponent's LP.
  • "Hailon" inflicts damage to the opponent equal to the difference between the controller's LP and the opponent's LP. In Tag Force 6, this effect only activates if the controller's LP is lower than the opponent's.
  • "Raphion returns the monster it battled to the hand, and if it does, it inflicts damage to the opponent equal to the ATK of that monster. In Tag Force 6, it only inflicts damage and does not return the monster.
  • "Gabrion" shuffles all cards the opponent controls into the Deck. In Tag Force 6, it targets 1 card the opponent controls and shuffles it into the Deck.
  • "Sandaion" inflicts 4000 effect damage to the opponent. In Tag Force 6, this damage is lowered to 2000, and additionally, the opponent takes no battle damage from attacks involving it.

"Sephylon" is in a class of its own, having none of the effects of the first 10 "Timelords". In the anime, it cannot be Special Summoned, except by "Infinite Light", but can be Normal Summoned/Set. Each turn, it could Special Summon as many of the other "Timelords" as possible back from the hand, Deck, or Graveyard, and make the ATK of those monsters become 4000. It also gains ATK equal to the combined ATK of all other "Timelord" monsters on its controller's field, negate the effects of any monster it battles, and protect itself from destruction, and its controller from battle damage (if any), by banishing another "Timelord" monster the controller controls. In Tag Force 6 and the OCG/TCG, "Sephylon" cannot be Normal Summoned/Set, but can be Special Summoned by having any 10 or more monsters in the Graveyard. Once per turn, it can Special Summon 1 Level 8 or higher Fairy-Type monster from the hand or Graveyard and make its ATK become 4000, but it has its effects negated.

So far, the "Timelords" released in the OCG and TCG are "Metaion", "Lazion", "Zaphion", "Sadion", "Kamion", and "Sephylon". A number of Tokens have also been shown off as Boss Duel exclusives.

While the "Timelords" cannot be destroyed, they are not invincible, and can still be removed from the field by other means, such as by being banished or Tributed. It is also possible to remove them from the field by returning them to the hand or Deck, although returning them to the hand is less useful since they can simply be Summoned again next turn. Their Summon can also be negated by a card like "Solemn Warning". To overcome these weaknesses, cards that protect against direct attacks can be useful.

In addition, cards that can negate a "Timelord's" effects are extremely useful, as that will strip them of all their protection, generally leaving the opponent with a 0 ATK monster that cannot do anything. (However, this will be less useful against "Sandaion" and "Sephylon".)

Since all "Timelords" are Level 10, cards like "Level Limit - Area B" and "Gravity Bind" can easily prevent them from attacking and being able to use their powerful effects. Since it is very difficult to control more than 1 "Timelord", cards like "Scrap-Iron Scarecrow" and "Threatening Roar" are also very effective at stopping their attacks.

Cards that can attack the opponent directly, such as "Earthbound Immortal" or "Toon" monsters can be very useful against "Timelords", as they can bypass their protection and effects and deal your opponent significant damage in the process.

"Timelords" rely on attacking for their effects to go off, so any number of basic stall cards that aim to block the opponent's attacks will stop them as well, including battle position changers. However, this weakness can be overcome by using cards that force the "Timelord" monster to be attacked.


  • In the anime, all the Timelords have a Rare rarity with exception of "Sephylon", which has an Ultra Rare rarity instead.
  • Time Lords are of a race of time-manipulators from the series Doctor Who.
    • "Sephylon" was originally named "Sephylon, the Ultimate Time Lord", but this was later changed to "Timelord" to be consistent with "Metaion".
