The Proto-Tool is the primary weapon that Rook uses. The Proto-Tool is a high tech multi-functional weapon that can turn into a blaster, power sword, quantum staff, bow, grappler, shield, fishing pole, and numerous other equipment. Rook currently holds the one and only Proto-Tool. Rook has stated that he has made some "special modifications" to his personal Proto-Tool although he didn't say what they were. When not in use or on standby, Rook wears the Proto-Tool on his left shoulder. Rook's first Proto-Tool was absorbed by Malware in Showdown: Part 2. Rook eventually received a replacement.
