Anime/Manga Superstars

[The KKM]

also is the Megaman series part of an anime if so I'm thinking about making Roll (Kid Roll) like Marvel v.s. Capcom

Here's a picture

Main article: List of characters in the Mega Man Battle Network series
The series focuses on Lan Hikari and his NetNavi, MegaMan.EXE as they build their friendship while dealing with threats from various NetCrime organizations. Along with Lan are friends Mayl Sakurai, Dex Ogreon, Yai Ayano, Tory Froid, and their respective Navis: Roll, GutsMan, Glide, IceMan. Although the series originally remains fairly close to the games in terms of storyline, it begins to diverge greatly partway into the series. For example, there is no evidence showing that Lan and MegaMan were twin brothers in the anime, unlike in the games where it is revealed near the end of the first Battle Network game.

Yup! She's in the anime so its more than fine.
Also maybe for 7/8koma she can get her .EXE outfit as a transformation?

Or aren't they really related? I'm not really sure how it works these days with so many Megaman games out there now.

They're different characters, .EXE is sort of an alternate reality to the classic games. But there was an OVA based on the old games, so I guess Roll can be in.
