The opposite of "trans fused" is "separated" or "isolated," meaning to be pulled away or split apart. A related antonym is "disconnected," which refers to the lack of connection or cohesion between otherwise related parts. Another antonym could be "dismantled," which describes the deconstruction of something that was previously joined together. In contrast to "trans fused," "fragmented" describes something that has been divided into smaller and separate pieces. Finally, "disassembled" can be considered an antonym as well, explaining the process of taking apart the pieces of something that was once whole.
