Punk.EXE

Punk.EXE is the second NetNavi used by Mr. Famous. He only appears in the Blue (Black in Japan) version of MegaMan Battle Network 3, being absent in the White version. He is also the only navi used by Mr. Famous that is based off of a Robot Master.

MegaMan Battle Network 3
Punk appears as an optional boss in the game. Mr. Famous appears in Yoka, where he gives a secret to Lan Hikari and asks if he wants to NetBattle, using Punk as his Navi. Defeating him will always give only Zenny. If MegaMan has the Navi Customizer program Collect and defeat Punk, no data will be received.

Rockman EXE Beast
Punk appears in episode 3 of Rockman.EXE Beast as a Zoanoroid working for Falzar. Makoto Aoki was creating CopyBots, but wasn't successful in making them work. Falzar learns about the CopyBots and orders Punk to steal them to be used by his army, allowing NetNavis attack the real world. When Makoto was successful into making one CopyBot function, Punk hijacks the CopyBot and captures her. Punk tests the CopyBot in the city, and forces Makoto to make several of them. When enough CopyBots where completed, Punk sees no more use for Makoto and tries to kill her, but Mr. Famous appears and saves her. Lan and Chaud appear shortly after, as they discovered what happened when they saw Makoto and Punk in a security camera of the area Punk had attacked. They fought against Punk with Cross Fusion, and deleted him with a Program Advance. However, Punk is successful in his mission, as a truck filled with CopyBots is sent to Falzar.

Abilities
Punk is very agile and can detach his shoulders to throw them like cutting boomerangs or use them as shields, and can enclose himself into his shoulders to become a cutting wheel. He can also stretch his left arm, using it like a flail to attack or wrap his opponents.

In the game, Punk has the following set attacks:
 * Mad Roller: Punk spins in the top or bottom row, moves in the column MegaMan is currently located, and returns to his area in the opposite row he came from. He can't be harmed while using this attack.
 * Wave Mad Roller: Punk spins throw all the area forward him. He can't be harmed while using this attack.
 * Shield & Chain: Punk uses his right shoulder as a shield and stretches his left arm to attack MegaMan from behind.
 * Punk Chain: Punk appears in front of MegaMan to slam him with his arms. This attack is used during the Double Go Round.
 * Double Go Round: His shoulders spin through the area and he uses Punk Chain.

Battle Chip
Punk has a Mega Chip in the game, but it could only be obtained from a promotion held by Capcom in Japan. However, it can also be gotten via a cheat device, being the only way to obtain this chip in the U.S. version. When used, Punk uses his Mad Roller attack, rolling in the lower row, moving up in the closest enemy, and returning by the upper row.

If the player obtains Mr. Famous's wristband (WrstBand) in NumberMan.EXE's Number Trader, the attack of Punk's chip is replaced by the Wave Mad Roller, the power of the Punk Chain increases, and he can use Double Go Round. The wristband can be obtained normally in any version of the game.

Punk can use different attacks if the player use the chip in certain conditions:
 * Wave Mad Roller: Used when MegaMan has 1/4 of his health. Causes 360 damage. Becomes the standard attack with the wristband, causing the same amount of damage.
 * Shield & Chain: Hold left+B when Punk appears. Causes 400 damage and confusion status. This attack isn't affected by the wristband.
 * Punk Chain: Use his chip in the middle panel in the corner of your area while the Mega Buster is fully charged. Causes 200 damage, 400 with the wristband.
 * Double Go Round: Like Punk Chain, use his chip in the middle panel in the corner of your area while the Mega Buster is fully charged. Press down, right, down, right when he appear. Each shoulder causes 100 damage, and his Punk Chain 400 damage. This attack can only be used with the wristband.

Trivia

 * Keiji Inafune liked the original Punk very much, so much so that he used his influence as producer to include Punk in he game and redesign him personally.
 * Punk is the only NetNavi based on one of the classic series' three Mega Man Killer series robots.
 * Punk is the only boss from MegaMan Battle Network 3 to not have a Omega version, but data for a Punk Ω battle is contained in the game.
 * A peculiar quirk about Punk is that any obstacle-involved attacks thrown at him are destroyed on contact with him. This means that the YoYo series only hits him once. However, while under the effects of the Z-YoYo Program Advance, the player can attack as soon as the YoYo returns or is destroyed, and since the Program Advance does not induce flinching, it allows for the player to attack as fast as the player can mash the A button.
