For his Mega Man Maverick Hunter X incarnation, see Chill Penguin/Maverick Hunter X.

Chill Penguin, known in Japan as Icy Penguigo (アイシー・ペンギーゴ Aishī Pengīgo), is a Maverick fought in Mega Man X, Mega Man Xtreme, and in the Boss Attack mode in Mega Man Xtreme 2. A Reploid based on a king penguin designed for operating in sub-zero temperatures, Chill Penguin was a Maverick Hunter from the 13th Polar Unit that was deployed to guard a station at the South Pole, but soon grew tired of his dull, isolated life. When the news of Sigma's uprising reached him, he saw his chance to return to civilization and destroyed his own commander, made his escape, and joined up with Sigma and other Mavericks.

He's rowdy and belligerent despite his small stature, and there is a strong animosity between him and Flame Mammoth due to Mammoth being a bully toward smaller Reploids and Penguin being jealous of his large size.


Mega Man X

Chill Penguin is one of the eight bosses in the Stage Select Screen. As part of Sigma's forces, Penguin planned to use avalanches to crush cities near mountains under tons of snow, and X had to stop him. If the player defeats him before Flame Mammoth, the lava in the latter's stage will be frozen, allowing X to walk over it with impunity.

Mega Man Xtreme

A digital reproduction of Chill Penguin appears as a boss in the Hunter Base's Mother Computer. He fights in the same way as the original version.

Mega Man Xtreme 2

Chill Penguin, alongside the other bosses from Mega Man Xtreme, appear in the Boss Attack Mode.

Rockman X DiVE

Chill Penguin appears as a boss in the last stage of Chapter 4 from the story mode. He fights in the same way as his original appearance, but with an extra effect: When he jumps to the ceiling to create a blizzard, the walls wil be temporarily frozen, making the player unable to Wall Kick. The player can also obtain his boss chip to use Shotgun Ice.

Chill Penguin appeared as the boss from the summer event in 2020, having a summer design and the name Summer Penguin. He releases water balls instead of ice, and when he jumps to the ceiling, a large wave appears to push the player.

Other appearances

  • In Rockman ×over, Chill Penguin is the boss of the tutorial and one of the four bosses from World 1. He also appeared as Battle Memory.
  • Chill Penguin appeared as an unit card in TEPPEN.
  • Chill Penguin appeared as an enemy in the Mega Man X event from Zombie Cafe.


Chill Penguin occupies a base in snowy mountains in Mega Man X, and an Abandoned Missile Base in Mega Man Maverick Hunter X. Most players tend to fight him first, as some see him as the easiest boss to defeat with the X-Buster, and the Foot Parts are also in the middle of his stage (it is replaced by the Head Part in the remake Maverick Hunter X, that can only be obtained with the Foot Parts).

In all games, he shoots ice rocks either straight forward or on the ground, slides across the arena on his belly, creates two ice penguin sculptures with his breath (which can also freeze X), and pulls a switch on the ceiling that creates a blizzard to push the ice penguins and X. It is a good time to shoot him with a charged shot when standing face to face with him or when he stops sliding; he will not create ice penguins when attacked this way. On higher difficulties in Mega Man: Maverick Hunter X, he will also use the Shotgun Ice, which requires X to move to the opposite side of where Chill Penguin jumps and fires the Shotgun Ice projectiles at the wall to avoid taking damage.

The contents of the tank on his back may be combustible, so he is easily burnt with Fire Wave, which is also useful against him in the Boss Attack Mode from Mega Man Xtreme 2. The Speed Burner works just as well against him in Mega Man Xtreme.

Other media

Rockman X manga

Chill Penguin is the first Maverick that X fought. He took control of a base from the 13th Polar Region Unit and was making earthquakes to create an avalanche. Marth, the commander of the base and a friend of X, was frozen by Chill Penguin. Chill Penguin has the advantage in the beginning, but is surprised by X's abilities and uses Marth as a shield. An earthquake awakened Marth and he gets freed from the ice, restraining Chill Penguin so that X could use a charge shot, killing both.

Rockman X Mega Mission 2

Chill Penguin was revived as "Icy Penguigo L". His color scheme now consists mainly of red, with yellow, black, white and dark blue highlights. He has two tubes connected to the devices on his back instead of one, and also has design changes to his head and shoulders. He was defeated by X.

Rockman X The Novel: Irregulars Report

X8NavigatorAlertIconEdit This section requires expansion.

Chill Penguin joined Sigma because he didn't like how he was treated due to his penguin design, developing a hatred for humanlike Reploids. When facing X, he is enraged because of the Hunter's humanlike appearance and is subsequently defeated by him.

Mega Man (Archie Comics)

Chill Penguin's body is briefly seen in Sigma's arctic base in Sonic Universe #76. He would later be the first Maverick revived by Sigma in his base on the Lost Hex. Sigma quickly noted that his DNA Soul was not perfectly duplicated, but was appeased when he realized that the clone of his former lackey retained his complete loyalty to Sigma. Many other Mavericks soon followed, forming a massive army that Sigma employed against the heroes who opposed him.

Rockman Battle & Chase

Chill Penguin and his vehicle

Chill Penguin is one of the participants from the Battle & Chase, racing in a penguin-like vehicle. Chill Penguin, alongside his friends Ice Man and Blizzard Man, entered the race so they could use the prize money to travel to Antarctica. While racing in a hot desert, Napalm Man used Napalm Bomb on his opponents and set Chill Penguin's vehicle on fire, and he used Shotgun Ice to extinguish it. Seeing his abilities, Napalm Man captured Chill Penguin and threatened him to keep him cool. Chill Penguin refused and caused trouble to Napalm Man, angering him, and he throws Penguin out of his vehicle. Mega Man saves Chill Penguin and destroys Napalm Man's vehicle. While he lost the race, Chill Penguin leaves happy alongside Ice Man, Blizzard Man, and their new friend Shadow Man.
