• If this monster is Special Summoned by the effect of "Ultimate Insect LV3", but is then flipped face-down, or removed from play with "Interdimensional Matter Transporter" or "Dimensionhole", its effect is reset, so even if flipped face-up again, it will no longer decrease the ATK of the opponent's monsters.

• You can Special Summon "Ultimate Insect LV5" with the effect of "Ultimate Insect LV3" even if that "Ultimate Insect LV3" was not Special Summoned by the effect of "Ultimate Insect LV1".

• Ultimate Insect LV7: If "Ultimate Insect LV7" is Summoned by the effect of "Ultimate Insect LV5", but is then flipped face-down and then face-up again, its effect is reset and will no longer be applied.

• Ultimate Insect LV7: If you have 2 copies of "Ultimate Insect LV7" each Summoned by the effect of "Ultimate Insect LV5", then the ATK and DEF of your opponent's monsters are reduced by 1400 points.

• If a level monster fulfills its condition to Special Summon the next-highest level (for example, if "Armed Dragon LV5" destroys a monster as a result of battle), and the level monster is then flipped face-down, or removed from play permanently, or sent to the Graveyard and then Special Summoned from the Graveyard, then its condition is reset and it is no longer considered to have met the condition to level up to the next level.^{[13][14][15][16][17]}

• If you don’t have "Horus the Black Flame Dragon LV6" in your hand or Deck, you cannot send "Horus the Black Flame Dragon LV4" to the Graveyard to activate its effect.^[14]

• "If Banisher of the Light" ^[sic] is in play, you cannot send "Horus the Black Flame Dragon LV 4" to the Graveyard, so you cannot activate its effect.^[14]

• You don’t have to send "Horus the Black Flame Dragon LV 4" to the Graveyard if you don’t want to, even if it destroyed a monster as a result of battle. But if you activate its effect by sending it to the Graveyard, you must Special Summon "Horus the Black Flame Dragon LV 6" if possible.^[14]

Mentions in Other RulingsEdit

• Divine Wrath: You can activate "Divine Wrath" when a "LV" monster is sent to the Graveyard to Special Summon the next level version (an Ignition Effect), and "Divine Wrath" will negate that effect, even though it cannot destroy the "LV" monster because it is already in the Graveyard.

• Level Down!?: You can use “Level Down!?” on a “Neo-Spacian Dark Panther” that is copying an LV Monster. But since it is no longer copying the LV Monster after it has been returned to the Deck, no monster will be Special Summoned.

• Level Modulation: An “LV” monster that normally cannot be Special Summoned except by the method in its text CANNOT be Special Summoned from the Graveyard with “Level Modulation” unless it has been previously Special Summoned by the correct procedure. The “ignore the Summoning conditions” text allows for these monsters to be Special Summoned only after they have been properly Summoned by their own effect. This applies to “Horus the Black Flame Dragon LV8”, “Armed Dragon LV7”, “Silent Swordsman LV7”, “Silent Magician LV8”, and “Winged Kuriboh LV10”.

• Neo-Spacian Dark Panther: If you target an “LV” monster, you could Tribute the “Neo-Spacian Dark Panther” to activate the Spell Card “Level Up!”. It will be in the Graveyard when “Level Up!” resolves, so it will no longer have the copied effect, so there is no monster name to reference and therefore the effect disappears.
