Make a Negative Monster Game (because I have an obsession)

[|0P|]

    Pretty much the same as every other "Make a ___ Card" game just with my own (not particularly original) Sub-Type. And because I need something to do when I'm bored I'll try my best to make images to go with any cards that aren't given any and add them here

Rules

1. All monsters must have the "Negative" Subtype and have either the "Negative Clause" (see rule 2) or an effect that allows their Level or Rank to become a negative number OR must directly support/be supported by Negative monsters.

2. All monsters types can be Negative except Link due to the lack of a Level or similar attribute that can be given a Negative value, Links that require Negatives as tribute or benefit from being linked to them are allowed.

3. Suggestions can come in the form a card name, a Type/Attribute, an additional Sub-Type, an effect/premise, or any combination of the 4

beyond that it's the basic rules

4. If you create a card leave a prompt

5. You must respond to the most recent prompt only

(Not a rule, more a design note to keep in mind, Negative monsters tend to have strange effects such as having no Attribute or only being able to be summoned during your opponents turn)

to get the ball rolling here's some examples of what you can do with Negative monsters

Spoiler

 

A basic archetypal searcher aside from the "Negative Clause"

It's "Negative Clause" is worded differently to allow for it's Level changing effect, it also happens to be a Pendulum monster and Tuner that lets you Synchro Summon during your opponents turn by using it while in the Pendulum Zone

This one has the option to not even be considered a Negative monster, along with the Arcana gimmick of having different (but similar) effects depending on a coin flip.

"When this card is summoned flip a coin, if heads this card level is treated as -4, if tails this card is not treated as a Negative monster. While this card is a Negative monster you can tribute this card, special summon one "Discordian" monster from your deck, it must be treated as a Negative monster and it's level becomes equal to it's current level x-1. While this card is not a Negative monster you can tribute this card to special summon one "Discordian" monster from your graveyard, it cannot be treated as a negative monster and it's level cannot be changed."

an otherwise generic Xyz monster that happens to be Negative.

"2 Level -5 monsters
You can detach one Xyz Material from this card, activate one of the following effects;
- Target one card in your graveyard, return it to your deck.
- Draw one card then, if it was a Negative monster, draw one card.
After one of this cards effects resolves inflict 300 damage to your opponent. This card's Rank is treated as -5."

 

As for a suggestion how about a monster that has effects based on the combined Levels of all monsters on the field, the closer to zero the better the effect.

You never really explained how they work exactly.  I assume they're basically just Main Deck monsters, but with a negative level?

Escher Monstrosity
DARK -********
Beast/Negative/Effect
You can tribute 2 monsters whose combined total Levels equal 0: Special Summon this card from your hand or GY.  You can only control 1 "Escher Monstrosity".  If the combined total Levels of all monsters you control equals 0: You can destroy all other cards on the field.  You can only use this effect of "Escher Monstrosity" once per turn.  This card's Level is always treated as -8.
3000/3000

Next: Make another generic Negative Monster

my bad, thought it was self explainitory, it's just any monster who's Level/Rank is/has the capability of being a negative value

False God's Vessel

DARK
Psychic/Negative/Effect
Level 4 - 1100/2100

(This card's Level can be treated as Level -4.)

I got this one

"When this card is destroyed by battle and sent to the Graveyard: You can Special Summon 1 Negative monster with 1500 or less ATK from your Deck, in face-up Attack Position. This cards level is always treated as -4"

You can shuffle 1 Level 4 "Ying-Yang" monster from your GY into your Deck to Special Summon this card from your hand.  If a card(s) is shuffled from your GY into your Deck: You can target 1 monster on your opponent's side of the field or their GY; shuffle that target into the Deck.  This card's Level is always treated as -4.
1800/1400

 

Next:

Either: Another "Ying-Yang" monster OR a Level/Rank Neg-5 to Neg-10 monster (or both, if you're feeling really ambitious)

(By the by, can you repost Escher Monstrosity?  I don't think I ever saw it...)

I put all of them in a spoiler at the top as well as replying to with them to the original post

(Light/Dragon/Negative/Effect/8/2800/2400)

"This card is always treated as a "Ying-Yang" monster and "Light and Darkness Dragon", This card is also treated as DARK-Attribute. This card cannot be Summoned except by it's own effect. When "Light and Darkness Dragon" is sent from your GY to your Deck you can Special Summon this card. Once per chain, during either players turn, you can shuffle one "Ying-Yang" Monster or "Light and Darkness Draogn" from your GY into the deck, negate the activation of a Spell, Trap, or Monster effect and destroy that card. This card's Level is also treated as -8."

for some reason that was the first thing I thought of, anyways how about the "false god" from Lystêrns card as an upgrade for it

[Naidraug]

False God's Manifestation

Dark

Psychic/Negative/Effect

Level 8

3000/2100

(This card's Level can be treated as Level -8.)

This monster cannot be Normal Summoned/Set. this monster cannot be Special Summoned, except by its own effect. You can tribute 2 Negative monsters you control; Special Summon this card from your hand or GY. You can only use this effect of "False God's Manifestation" once per turn. If this card battles an opponent's monster (Quick Effect): you can banish 1 Negative monster from your GY; banish the opponent's monster this card is battling, then your opponent takes damage equal to half the combined ATK of the monsters banished by this effect. If this card was Special Summoned by tributing a "False God" monster, this card gains the following effect:

- Once per turn, during your End Phase; you can return 1 banished Negative monster to your hand.

"1 Tuner + 1 or more Negative Monsters
When a monster is Synchro Summoned using only this card and other Synchro Monsters as Materials Special Summon the other Synchro Material Monsters. This card's Level is always treated as -5."

I wanted to try for something that, while difficult to use with Link monsters being a thing, can theoretically be splashed into any deck seeking to quickly fill the board with synchro's, more specifically for when you don't have enough zones to get out materials and you don't want to lose the Synchro's you already have. I also really wanted to come up with a name who's acronym is "GAS"

how about a Fire monster?

[Tinkerer]

Charcoal Slime

FIRE -**

Aqua/Tuner/Effect

If this card is Summoned: You can Special Summon FIRE monster from your GY with 200 ATK and a negative Level. This card's Level is always treated as -3.

200/900

 

A Negative monster that supports an irl archetype.

what do you think of the different borders and text box?

[Tinkerer]

Definitely has a more distinctive look, I'll give it that. I like it more than the original design, personally.

Also, I realize I messed up a few things on the last card. I wanted it to be Level -2, but I forgot to change it in the effect text. I think you caught the other mixed up stuff though.

Subterranean Arachne

Level -6

DARK Insect

Dark Synchro/Effect

"Underground Arachnid" - Any number of DARK Tuner monsters

ATK: 2400

DEF: 1200

When Synchro Summoning this monster, instead of adding the values of the levels, you subtract the combined value of the Tuner monsters levels from the level of the non-tuner monster.

When this monster is Synchro Summon, equip as many monsters your opponent controls to this card as possible. This card equipped with a monster cannot be destroyed. If a card on the field is destroyed, you can equip it to this card. If your opponent would activate a spell or trap card or effect, you can banish a card equipped to this card to negate that card or effect and shuffle it into the deck.

 

Next: Negative XYZ "Number" monster.

while your participation is appreciated, this is technically an invalid submission, "Dark Synchro" and "Synchro/Negative" monsters aren't the same thing and have different summoning requirements, along with that, due to not being a Negative Monster, this card wouldn't be able to support/be supported by an cards that synergize with Negative monsters. a more appropriate submission would be

Subterranean Arachne

Level -6

DARK Insect

Synchro/Negative/Effect

1 tuner + 1 or more monsters including "Underground Arachnid"

ATK: 2400

DEF: 1200

When this monster is Synchro Summon, equip as many monsters your opponent controls to this card as possible. This card equipped with a monster cannot be destroyed.

on a more personal note, i'm not a big fan of this one. what's the point of giving an existing archetype access to negative monsters if you aren't going to give them a way to play around with all the nonsense math you can do with positive/negative number interactions?

I'm sorry, I'm not quite sure I understand what this is supposed to mean. I could do it again with another one if you want?

Edited July 20, 2025 by eseer

[|0P|]

as an example, a monster with a Burden of The Mighty style effect (-X00 atk per level) would actually raise a negative monster's atk, let's say we've got a lvl -4 monster with 1000 atk and the effect reduces by 100 per lvl, that would be 1000 - -400. anything minus a negative value is equivalent to that same number plus the positive equivalent of that value, so 1000 - -400 = 1000 + 400 = 1400

[eseer]

Alright, now, lemme do another one.

 

Super Quantum Enemy Demoniacal

EARTH Fiend

Level -6

Negative/Effect

ATK: 2000

DEF: 2000

This card's Level is always treated as -6. Banish this card if its level becomes 0 or higher. Shuffle this card into the deck if its level becomes -12 or lower. Once per turn, you can reveal 1 "Super Quantum" monster from your deck and choose either 3, 4, 5, or 7. Special summon that revealed monster, increase this monsters level by the difference (A negative value reduces this monsters level) and change that monsters level to the declared level. If you control a monster(s) with a level equal to this monsters level *-1, this monster and those monster(s) cannot be removed from the field.

as someone who's never tried super quant but loves their aesthetic, this is a fascinating idea. could easily see this being a whole sub-archetype build around rapidly changing levels and "corrupting" the main super quantum monsters! hoipe you don't mind, i changed the wording slightly to what i think would make the effect easier to understand, though i did end up making it a lot wordier;

"This card's original Level is always treatd as -6. Once per turn, you can reveal 1 "Super Quantum" monster from your deck and choose either 3, 4, 5, or 7; Special summon that revealed monster, then increase or decrease that monsters and this cards Level until the summoned monster's Level becomes the chosen number. If the combined levels  of monsters you control equals 0, they cannot be removed from the field except by this card's effect. if this card's level becomes -12 or lower, Shuffle this card into the deck, if this card's Level becomes 0 or higher Banish this card."

oh fuck I just had a genius idea, mind if I make another one?
