Claw Mark

Code is able to leave marks of his studded black bands across any surface. Once applied, Code is able to instantly travel to any of them, even if they're in a different dimension. While it only allows him to move through them, he can take one other person with him at a time. Despite this, Amado doesn't consider this ability to be space–time ninjutsu. While mostly used in battle or for transportation, Code also employs them as a means of communication, putting his mouth or ear through them to contact Ada. According to Kawaki, while mostly chakra-based, the marks are also made from the iron in Code's blood, enough for them to be considered physical matter that the Kāma can't absorb.
