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 Reploid designed after a king penguin. Formerly a Maverick Hunter, he joins Sigma's rebellion and becomes a Maverick lieutenant.


Chill Penguin is a loud-mouthed individual who is always searching for excitement. He is rowdy and belligerent despite his small stature. He makes for a keen soldier and was an important part of Sigma's rebellion.

Chill Penguin seems to have trouble getting along with his comrades. There was 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. Additionally, Storm Owl did not get along with Chill Penguin, because someone once confused Owl with a penguin due to his short stature.[3]


Mega Man X

Chill Penguin was designed to operate in cold temperatures, which made him a natural fit for 13th Polar Unit. However, he grew bored of working at the South Pole with little to do. This made it easy for Sigma to sway him to his side; he saw his chance to return to civilization and destroyed his own commander, escaping to join Sigma and the new Maverick army.

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.

Chill Penguin reappeared in the second stage of Sigma's Hideout as an obstacle for X along with his fellow Mavericks.

Mega Man Xtreme

A digital reproduction of Chill Penguin is fought as a boss in Mother Computer in Normal Mode. He fights in the same way as the original version, and even has a similar stage. Alongside the other bosses from Xtreme, he reappears in Mega Man Xtreme 2's bonus Boss Attack Mode.


Most players tend to fight Chill Penguin 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. Despite his wide arsenal, many of his attacks are easy to dodge with proper wall climbing and dashing.

Chill Penguin is weak to the Fire Wave, where hitting him with said attack causes his back to ignite for a short while, suggesting that the contents of the tank on his back may be combustible. The Fire Wave 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.


  • Shotgun Ice (ショットガンアイス) - Chill Penguin spits four chunks of ice. Some travel straight through the air, others slide along the floor.
  • Sliding (スライディング) - Chill Penguin slides on his belly, bouncing off of walls if he hits them.
  • Ice Sculpture (氷の像) - Chill Penguin breathes snow, creating two penguin-shaped ice sculptures. X can break them, but if he gets caught in the snow he will freeze as well.
  • Blizzard (吹雪) - Chill Penguin grabs the hook on the ceiling, causing a blizzard to push X backwards. Pushes ice sculptures backwards as well, which shatter on walls.
  • Chill Penguin also jumps into the air, attempting to land on X.

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.

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 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.

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.
