In theory, Exodia could be negated by certain card effects that specifically negate the activation or effects of a card. For example, cards like "Solemn Judgment" or "Solemn Strike" could be used to negate the summoning of Exodia or its individual pieces. However, since Exodia's win condition is based on having all five pieces in the hand, negating one piece may not prevent the opponent from winning with the other pieces. Ultimately, while Exodia can be negated in theory, it may not always prevent the opponent from achieving victory. **

A negated subnet mask is a subnet mask that has been inverted or "negated" to represent the opposite of the original subnet mask. In a negated subnet mask, the bits that were originally 0 become 1, and the bits that were originally 1 become 0. This is often used in network calculations to determine the range of IP addresses that are not included in a given subnet. It can also be used to identify the network and broadcast addresses for a given subnet. **

Additionally, certain monster effects or spell/trap cards can prevent Obelisk from attacking altogether, effectively negating its attack. **

No, the effects of Chaos Dragon cannot be negated. Chaos Dragon's effect is not able to be negated by cards that negate the effects of monsters, spells, or traps. This makes Chaos Dragon a powerful and difficult card to counter once it is on the field. Players must find other ways to deal with Chaos Dragon's effects, such as removing it from the field or preventing it from being summoned in the first place. **

No, not all Special Summons are negated by Solemn Strike. Solemn Strike specifically negates the Special Summon of a monster, but there are other types of Special Summons that it does not affect, such as the Special Summon of a Spell/Trap card or the Special Summon of a monster from the hand or Graveyard by a card effect that does not specifically Special Summon the monster. It is important to read the card text carefully to determine if Solemn Strike can negate a particular Special Summon. **
