Frost Walrus

"They sent a kid like you after me? I promise to end this quickly..."

- Frost Walrus

Frost Walrus, known as Frost Kibatodos (フロスト・キバトドス) in Japan, is a large walrus-based (sealion-based in the Japanese version) Reploid and one of the Maverick bosses in Mega Man X4.

History
Frost Walrus was a short-tempered, rowdy Reploid whose destructive behavior got him marked for disposal as a Maverick. However, he was saved when General gave him a chance to join the Repliforce, a military organization of Reploids. Walrus would continue his violent ways, and felt that rampaging through enemies was a military man's duty. When the Great Repliforce War started, Walrus was impressed as it was a perfect excuse for him to riot as much as he liked. Walrus was stationed at Repliforce's base in a snowy region and put in charge of guarding their secret weapon under construction. The Hunters eventually found out about the secret project, and dispatched members of their elite team to stop Walrus. Walrus refused to surrender or stop his actions in the coup d'etat, and the Hunters were forced to destroy him in battle for his Maverick actions, his luck finally running out.

Power and abilities
Frost Walrus has great physical strength and is able to jump pretty high despite his size.
 * Body Blow - Frost Walrus slides on the floor to crush enemies with his large body. He will sometimes leap at the start of the slide.
 * Ice Blade - Frost Walrus either launches ice blades directly from his shoulders or uses his cold breath to create an ice block, then shatters it to release ice blades. The ice blades stay on surfaces.
 * Frost Tower - Frost Walrus creates an ice block and shatters it, sending spiked ice pieces across the room. The ice stays on surfaces.

Strategy
In battle, Frost Walrus will constantly walk towards the player and attempt to crush them by sliding on the floor. After sliding, Walrus will also launch ice blades that stay on surfaces. Once his health is reduced to half, Walrus will gain a new attack where he creates a large ice block and shatters it, causing spiked ice pieces to spread everywhere. Like other ice-based Mavericks, Walrus is weak to flame-based attacks; X and Zero can respectively use Rising Fire and Ryuenjin at close range to set Walrus on fire, dealing heavy damage in process.

Most bosses show the ability that the player will gain during the battle. For X, his Frost Tower is based on Walrus creating a large icicle that will explode into several shuriken-shaped pieces. Zero's Hyouretsuzan is based after Walrus' raining icicles.

When playing as Zero
Frost Walrus: What's that blonde kid up to?! I don't have time for you junior!

Zero: Hey! Shut up and fight me already!

Frost Walrus: Oh... That does it, you're goin' down!

Battle quotes
Frost Walrus had battle quotes in the original Japanese version that were cut from the English one. They are as follows:

Other appearances

 * Frost Walrus appeared in the X Challenge from Mega Man X Legacy Collection and Mega Man X Legacy Collection 2, being fought alongside Chill Penguin in the first battle.
 * Frost Walrus appeared as an Unit Card in TEPPEN, and in the illustration from the Action Card Uncanny Chill.

Rockman X4
Frost Walrus appears as a member of the Repliforce with the same backstory as the game: he was a Reploid with a volatile temperament whose penchant for havoc and destruction led to the authorities to call for his termination as a Maverick. However, General saved him by inviting him to join the Repliforce, sparing him from the fate of being killed.

He was visited in the Repliforce snow base by Colonel, who berated him for causing unnecessary riots that were unhelpful to the Repliforce's plans. During one such incident, he killed an entire squadron of Maverick Hunters and kept their bodies frozen in ice as part of a collection of his victims. Colonel informed him he will report his behavior to General, and that he should cease such wanton destruction in the future.

In a fit of anger, he released dozens of Reploid prisoners and told them to run as fast as they could, all so he could hunt them down and later killed all of them for sport. However, one was saved by X and Blizzard Buffalo, the latter of whom had become reformed as a Maverick Hunter. Frost Walrus proved to be more than a match for the two Hunters and easily overpowered them both. Throughout the entire battle, Walrus remained stationary and did not even have to take a single step to battle against them. X noted this in shock before he was ruthlessly impaled on Walrus' shoulder blade, causing him to lose consciousness. Blizzard Buffalo then stepped in to defend X. After X awoke, he discovered Buffalo was dead, impaled by a large icicle.

After preparation, the enraged and grief-stricken X rushed to the Snow Base and confronted Frost Walrus in a modified Eagle Ride Armor, where he infuriated Walrus by destroying his collection of Reploid victims encased in ice. Even though Frost Walrus quickly destroyed the Ride Armor with a Frost Tower, X still managed to heavily damage him by setting him ablaze with the Ride Armor's damaged fuel tank. Despite all this, Frost Walrus again gained the upper hand and attempted to kill X. Before he could kill X, Frost Warlus suddenly froze as General had arrived the scene, staring at him. Frost Warlus was then executed by General, who personally brutally shoots him as a punishment for his previous misconduct and to save X's life.

Archie Comics
Frost Walrus appeared in Archie Comics' Worlds Unite crossover between its Mega Man, Sonic the Hedgehog, Sonic Universe, and Sonic Boom lines, which also guest-starred the Mega Man X series and other Sega and Capcom franchises. He was revived by Sigma and employed as part of an army to attack various worlds.

Etymology

 * Frost Walrus's Japanese name Kibatodos (キバトドス) is a portmanteau of "kiba todo" (キバトドス), meaning "fanged steller sea lion".

Trivia

 * He is one of the two Mavericks that Zero tells to "shut up and fight", with the other being Metal Shark Player from Mega Man X6. This is surprising, due to the fact that he tries to persuade the other members of Repliforce to stop the coup. It's possible, though, that Walrus's personality and his "blonde kid" and "junior" insults might have made Zero reconsider trying to reason with him.
 * In the manga Rockman X4, Frost Walrus had the unusual habit of consuming large amounts of vanilla ice cream, enjoying the flavor. This is the second time the fourth game's manga contradicted Vile's previous statement in the first game's manga about Reploids being unable to discern flavor like humans can, although this may be an additional upgrade over the course of time.
 * To some degree, Frost Walrus is the opposite of Blizzard Buffalo. He was a violent Maverick even before the Repliforce wars, as well as the only Repliforce member to genuinely be Maverick during the same event, while Blizzard Buffalo, even after being infected with the Maverick Virus, was a pacifist and was the only one of the infected Mavericks to technically not be a Maverick. This comparison was even highlighted in the Rockman X4 manga adaptation.
 * Frost Walrus can also be considered as the Mega Man X counterpart of Frost Man. They both have the word Frost in their names, are ice themed, are large and brutish, and reward the player with a weapon that generates powerful ice shards when defeated.
