Frost Walrus

Frost Walrus, known as Frost Kibatodos (フロスト・キバトドス) in Japan, is one of the members from the Repliforce. Like all the Repliforce, he was labeled Maverick because of their desire for independence. He guards a weapon inside the Repliforce Snow Base. His weapon is called Frost Tower, and he can also do a slide (like natural walruses). But like a lot of Ice element foes, fire is his weakness. So let him have it with Rising Fire or Ryuenjin, depending on your character.

Most bosses show the ability that you gain during the fight. For X, his Frost Tower is probably shown after Walrus makes a big, fat icicle that explodes in many pieces. Zero's Hyouretsuzan is used by Walrus for sending icicles in the air to crash down.

Trivia

 * Blizzard Buffalo and Chill Penguin make cameo appearances in his stage, frozen in ice. Blizzard Buffalo is in the beginning of the level, and Chill Penguin is in the Eyezard's room.
 * He is one of the two Mavericks that Zero tells to "just shut up and fight" with the other being Metal Shark Player from X6. This is surprising, due to the fact that he tries to persuade the other members of the Repliforce to stop the coup (though Walrus' "blonde kid" and "Junior" insults might have made Zero reconsider trying to reason with him).
