Data

Data (データ) is a little robot monkey friend of Mega Man Volnutt that was found by his side by Barrell Caskett. Data is mysterious and always appears when he is needed. Players can save the game, recover energy and obtain information by talking with him. He only talks with monkey sounds and Mega Man seems to be the only one who understands him, but it's later revealed Data can speak normally.

All of Mega Man's memories of Elysium and of The Master were downloaded into Data so that no one else could tamper with them. In Mega Man Legends 2, most of the information that was stored in Data is revealed in a long cut scene that explains the plot line. At the end of Mega Man Legends 2, he somehow manages to return to Earth to instruct Roll Caskett and Tron Bonne on how to built a rocket to retrieve MegaMan, but their bickering causes them to ignore him, leaving Data to lament on MegaMan being stuck there "for a little while longer".

Trivia

 * Data appears in the attack Lunch Rush used by Tron and Servbot in Marvel vs. Capcom 2, where several Servbots attack the opponent.
 * Data is always seen doing a dance similar to the dance called "The Monkey".
 * In the Megaman Battle Network series, Data makes a cameo appearance where in Yai's house, a plush doll of him is seen sitting on her couch.
 * Many fans joke around of him having a cup for a body. He can be annoying at times (eg. when Mega Man Volnutt is trying to steer the Flutter) but he seems to help a lot too. He really helps out at the end of Mega Man Legends as he stops Eden from destroying the people of Kattelox Island, making it the first time he talked in the series.
 * During the course of both of the Megaman Legends games, he appears as a save point and healing station. Sometimes in very dangerous places, leaving the mystery of how he got there. Near the end of one of the games, he is showing in a movie clip hanging on Megaman's back, possibly his mode of travel.I think data's gay.
