I Don't consider Aptom to be a Lost Number. He is beyond that at this point, and has become something else entirely. Lost Numbers may be genetic mutations and have unstable abilities, but they are still technically Zoanoids; Zoanoids that can never be replicated or controlled fully by a Zoalord. But Zoalord's still can communicate with a Lost Number telepathically. Guyot did this with the Lost Numbers as did Barcus. But Aptom freed himself from even the telepathic wave lengths of Zoalords. Aptom was a lost number but became something more. A new entity all together. He is not a Zoanoid, Lost Number or any Zoa-type for that matter. He's as he refers to himself: "The ultimate battle creature".
