N-7

Null-7, also known as N-7 and better known as Mereel, was one of six Null-class ARC troopers created for use in the Grand Army of the Republic. When he and his fellow Nulls were brought before the Kaminoan scientist Orun Wa, Jango Fett, and Kal Skirata for review, his friend Null-11, nicknamed Ordo, grabbed Skirata's holdout blaster, and threatened Wa with it. Skirata managed to get the weapon back, and received command of the Nulls as he was the only ones who could control them.

Mereel may have taken his name from former Mandalore, Jaster Mereel, Jango Fett's mentor.
