• This monster is based on a pun. In the anime it was previously established that Metalmorph creates mechanical or galvanised versions of the monsters it's applied to, whereas here it instead creates a monster that references the "metal" genre of music.
  • This is the only monster created with Metalmorph yet be released in the OCG/TCG.
• It is also the only one of Johnny Steps's monsters to be unreleased, provided it is considered distinct from Musician King.
