The bulk update request #9998 has been approved by @nonamethanks.
rename off -> off_(game)
rename the_batter -> the_batter_(off)
rename zacharie -> zacharie_(off)
"Off" by itself is too ambiguous. Just try to search "off" in the search bar. Wikipedia also listed it as Off (video game).
As for the characters, all but two have qualifiers. I think if most characters in a copyright have a qualifier, then everyone should have one. Besides, "The Batter" and "Zacharie" are also ambiguous, especially the latter.
(Keep in mind that I'm completely unfamiliar with this game, so I apologize if there is any mistakes)
