Wave Attack

Shockwaves (also known as Wave Attacks) are a special ability/attack in The Battle Cats and can be created by a few Cat characters and Enemy characters at a random chance or at a 100% chance.

Shockwaves hit all enemies/cats in their range but doesn't hit bases. (Levels are based on how many "explosion" sounds there are.) The damage done by Shockwaves is the same as a normal attack of the cat or enemy. Wave attacks tend to have more range than they seem to, as they have one extra hitbox in front of the last wave burst. This can be annoying sometimes, as a unit that should not have been hit can sometimes still be hit by the shockwave.

Trivia

• Kory is the first enemy in the game that can create a shockwave at a 100% chance.
  • Crazed Gross Cat is the first cat that can do a shockwave at a 100% chance.
• Enemy characters will create blue shockwaves and cat characters will create purple shockwaves.
• Shockwaves resemble the blast from a Cat Cannon.
• Certain units have the "Unharmed by Wave Attacks" ability, which means that they will always take no damage from any shockwaves that pass through it. However, they still can take damage from the attack triggering the shockwave if they are too close to the attacker. There is also a "Wave Blocker" ability, which stops any shockwaves that pass through it, and also seems to remove the final invisible hitbox of the shockwave, meaning that units like Eva Unit-00 can protect an Awakened Bahamut even if A. Bahamut has less range.
• Shockwaves operate at a delay, and they are a separate hitbox from the attack which triggered it, meaning that if the original unit which cause the shockwave is interrupted, the shockwave will still progress and deal damage independently. This can be seen when a Crazed Gross Cat attacks the enemy base in the Challenge Battle, triggering the summon of Assassin Bear, and even though the Crazed Gross Cat's attack has ended, the wave still progresses forward, killing Assassin Bear. 
• It is said that a shockwave's range works by adding range to a base value. According to various sources, the base value is 266.875 and for each level, add 200 range to it. This means that a Pigeon de Sable (level 1 shockwave) would have 1 x 200 + 266.875 = 466.875, explaining why it's able to hit Bahamut Cat, who has 450 range. Berserkory with its level 12 shockwave would have 12 x 200 + 266.875 = 2666.875 range in total.
  • For Cat units, however, the base value is smaller (~133). This means that, for example, Crazed Gross Cat's shockwave (which is a level 3 shockwave) will have range 200 × 3 + 133 = 733.
