SharkMan.EXE

SharkMan.EXE is the NetNavi operated by Masa or by his alter ego Commander Beef in the anime. SharkMan is quite powerful, with his "Fin Cutter" attack. In the anime, he is only seen when Masa is under the alias of Commander Beef, as Masa has denied having a Navi.

Description
SharkMan looks, of course, like a shark, but has no tail and instead has two legs, on which he can stand and fight. He is not a particularly large Net Navi, and his hunched back makes him look even smaller. But he is powerful, and in Episode 5 of MegaMan NT Warrior, when encountering MegaMan and Glyde, he leaves a good impression on them, with MegaMan telling Glyde that he thought that SharkMan "was only a legend".

MegaMan Battle Network
SharkMan is an optional boss operated by Masa.

MegaMan NT Warrior
SharkMan first appears when the WWW organization opens the locks at the aquarium, allowing all of the robot fish to escape. SharkMan initially appears antagonistic by harassing MegaMan and knocking him into the water. Glyde and MegaMan try to stop the viruses, but they are overwhelmed by a Jelly virus. However, SharkMan helps them defeat it by weakening it as MegaMan uses an ElecSword received from Commander Beef/ Masa. He reveals his true intentions of attempting to stop the viruses, but admits he was overwhelmed. SharkMan then jacks out. Apparently, he is known as a legend in the Cyberworld.

In the beginning of the N1 Grand Prix, Masa (under his alter ego of Commander Beef) enters SharkMan into the competition. He stalls his match against WhaleMan to allow Lan to master the Program Advance. Later, he and MegaMan go into a tag team Netbattle against StoneMan and BombMan near the final stages of the tournament. During the battle, SharkMan loses so that MegaMan can advance to the next round.

SharkMan later appears with Commander Beef in his various heroics usually along with WoodMan and SkullMan. Some involve him being turned to stone while fighting PharaohMan, and another results in his absorption by Gospel and being subsequently revived.

Manga History
In the manga by Ryo Takamisaki, SharkMan is well known among TV press as a powerful Navi who has won various Netbattle Tournaments. In the last tournament he won, he was annoyed by the absence of the two geniuses who defeat WWW (MegaMan and ProtoMan), as to fight them was his only motivation for entering the tournament in the first place. Some time afterwards, Masa arrives in DenTech City to have a big sale on his fish wagon. Dex Oyama arrives to win free fish, but was stomped by a crowd of adult ladies. Masa asked Dex if he knew where the genius (Lan) lived, but Dex pretends to be 'the genius' and is confront by Masa in a Netbattle. Leaving Roll to help GutsMan survive the battle, Mayl Sakurai leaves to call Lan to rescue Dex. After realizing he has been tricked, Masa orders SharkMan to finish GutsMan off, but MegaMan arrives and fights in his best friend's stead using the new original battle chip Lan made: Rock Booster. Although having some difficulty mastering it, MegaMan finally defeats SharkMan, and Masa congratulates Lan by giving away all the fish on his cart for free. After Masa leaves, Lan realizes there are still many strong fighters in the world and motivates MegaMan to train harder. Meanwhile, Miyu was watching them from behind...
