Iris.EXE

Iris.EXE is a NetNavi which always travels in a copy bot. She is the younger sister of Colonel.EXE. She had a crush on Lan Hikari and worked up the courage to almost tell him. She decided against it, as it would never work out between them. She was deleted after fusing with Colonel.EXE in order to delete Falzar/Gregar once and for all.

In the anime Rockman Beast she is the younger sister of the Beyondard Colonel.EXE and first comes from there to locate the Synchronizer: Trill.EXE She is Colonel's emotion data giving form and at the end of the anime partly merges with him, enough to return Colonel's emotions data but still remains as a net-navi. She always loved her big brother and she was a bit sad when Colonel was gone.

She is seen by Trill as an older sister considering how he refers to her as onee-chan.
