Horrorboros

"That's a orange. Do I even need to tell you to avoid the bombs that it periodically launches out of its mouth?"

- Mr. Grizz

Horrorboroses are King Salmonid that appear in Salmon Run Next Wave during an Xtrawave. They are the second type of King Salmonid to debut in Splatoon 3.

Description
A Horrorboros is a large, dragon-like Salmonid. It has a large mouth with a weapon device similar to that of the Steelhead's bomb. It spawns at the water's edge, slowly rises into the air, and slowly moves around the map, floating in a dragon-like manner. It uses an attack similar to the Booyah Bomb weapon as its main attack (albeit larger), charging it up using the contraption in its mouth and launching it down towards the players. Players can attack Horrorboros' body directly, or attack the bomb from its mouth until it bursts. Its bomb takes 2,500 damage to burst (each damage hurts Horrorboros directly), and the burst damage is 5,000. In other words, each successful burst cycle deals 7,500 damage to Horrorboros. Since each Egg Cannon shot only deals 800 damage to its body, it is advised to aim the shots at its bomb for massive damage.

A Horrorboros' health, like Cohozuna, is linearly correlated to the room's hazard level, using the formula, where HL denotes the hazard level percentage (capped at 60) and MaxHP is set at 55,000 for Horrorboros. For example, a team of Apprentice 40/99 (hazard level 8%) will meet a Horrorboros with 40,700 HP. When facing a team of Overachievers 0/99 (hazard level 60%) or above, Horrorboros has the maximum 55,000 HP.

Tips

 * In a similar manner to the Steelhead, the bomb Horrorboros charges up can be attacked. The bomb has 2,500 HP, and any damage to the bomb also reduces Horrorboros' health by the same amount. If destroyed, the explosion deals a huge amount of damage (5,000) to Horrorboros and cancels its Booyah Bomb attack.
 * Additionally, try to hit the bomb early before it gets too big. This way it is easier to destroy and can be done much faster.
 * Throwing Golden Eggs at the bomb can deal significant damage (800 each) to the bomb, which is faster than most supplied weapons. If you cannot connect a clear shot with a Golden Egg to the bomb, do not hesitate to throw the Golden Egg at Horrorboros normally, as every second counts.
 * Like Steelhead's bomb, any damage dealt to Horrorboros' bomb carries over to the next cycle (with the bomb painted partially in players' ink color) if players are unable to destroy it in the current cycle, until it is destroyed.
 * Horrorboros' large size and floating nature allow the team to deal damage to it virtually anywhere on the map.
 * Only using Egg cannon on Horrorboros without hitting its bomb at all would take 69 Golden Eggs to defeat it on the highest difficulty (55,000 HP), which is impossible in lower difficulties like Overachiever (due to not enough Boss Salmonid spawns) or could be extremely hard to perform if the team has trouble defeating Boss Salmonids. Instead, you should focus your Egg cannon shots on Horrorboros' bomb, and remember to use your main weapons against Horrorboros as well. Weapons with high damage per second are exceptionally good for this role.
 * For and, it is recommended to focus on shooting the bomb because of the main weapon's overstanding damage and range.
 * It is recommended to use on the bomb as well. The Crab Tank can theoretically deal 7,110 direct damage (by landing all 111 bullet shots with and one finishing ball of ink blow with ) on the King Salmonid, not including weak point damage, so use that to your advantage.
 * All other Special weapons help with defeating Boss Salmonids, dealing damage to the King Salmonid, or crowd control, so do not forget to use the one you get.
 * Remember that using the Egg cannon does not cost any ink and can take most of the Boss Salmonids in one shot, trading one Golden Egg for three most of the time.
