MegaMan Battle Network 6
Masa was mentioned at the end of game by Ms. Mari, saying that he, Sal and Miyu has sent a letter congratulating the students. All three of them being mentioned together was possibly a reference to their roles in the anime.

MegaMan NT Warrior
Maysa is a recurring character in the first part of the anime, where he is an energetic character, and fishseller who sells fish in the market. He pretends that he does not have a NetNavi and that he does not even understand the concepts of NetNavi, Net Battle, or PET, thinking Lan was talking about a real pet, like a dog, upon hearing him speak of PET. However, he understands the importance of the friendship between Navi and operator, as he has a Navi that is only used by him under the alter-ego "Commander Beef". Maysa secretly has a crush on Ms. Mari, which he rivalizes with Higsby.

As Commander Beef, he is the leader of a secret virus busting team which include him, Black Rose (Sal) and Mysteriyu (Miyu). He operates SharkMan, and the two are known to be a good team. He is a role model to Lan Hikari and the two have fought side by side before.

In Episode 5, he catches the kids not doing physical activity and gets them to do intensive exercise and learn fish facts. When the fish in the aquarium escape he helps Lan and co. evade the fish until they are forced into a corner. He then distracts the robot fish, allowing Lan to reach the aquarium. Maysa aids Lan by giving him the ElecSwrd Battle chip and using SharkMan to help MegaMan delete a Jelly virus. After the incident, he is seen staring off into the sunset, wishing the best for Lan.

Maysa participates in the N1 Grand Prix competition, one of his fights being against WhaleMan in Episode 15, where he takes it easy with the opponent to give Lan time to practice, defeating WhaleMan near the end of the time limit. In Episode 17, he and Lan team up and fight against StoneMan and BlasterMan, but SharkMan is disqualified by them. At the end of the episode, Lan figures out that Commander Beef is Maysa and proceeds to tell the rest of the gang. As his cover was almost blown, Miyu in a Maysa costume came riding on Maysa's bike and fools everyone and inadvertently makes Lan look like a fool, despite all the obvious hints at his real personality. In Episode 53, he is out to get a date with Ms. Mari competing as both Commander Beef and Maysa. He also aided Lan and his friends, along with Higsby and Ms. Mari, against the fight with the Life Virus.

MegaMan NT Warrior Axess
Maysa made a brief appearance in Episode 32 of Megaman NT Warrior Axess, returning in pursuit Gauss Magnus, who was believed to be involved in dark chip dealing. Sal And Miyu reveal Commander Beef's true identity to Lan, who then finds out that he, Ms. Mari, and Higsby were the only people fooled by his disguise (Maylu also hints at Black Rose and Mysteriyu's true selves, again Lan was the only one fooled). Maysa, Lan and friends team up to free Ms. Mari from Gauss and retain Beef's secret identity.

Rockman EXE Beast
Maysa has a Beyondard counterpart known as Commander Mask. Unlike the original Maysa, he leads a group of resistance fighters against the armies of Gregar and Falzar. He was last seen along with Miyu and Sal watching peace return to Beyondard. However, his personality was changed so drastically that many fans didn't recognize him until he said he's famous quote, "Take your calcium".

Rockman EXE Beast+
In Beast+, a JammingMan-produced clone of Maysa appears in Episode 24.

MegaMan NT Warrior
In the manga, Maysa is a skilled fishseller. SharkMan won a tournament when he first appeared, where he says he wanted to challenge the two kids that defeated World Three (Lan and Chaud). Maysa asks Dex if he knew about them, who in turn states that he is one of the kids. Maysa challenges Dex, saying that he can take all the fish from his stand if he defeats SharkMan, but GutsMan has trouble defeating him and Mayl calls Lan to help him. MegaMan defeats SharkMan and Maysa gives a lot of fish to them before leaving.
