- The Transformers Metroplex came with two large black weapons, generically labelled as "accessory cannons" in his instructions and identified as ion-pulse rifles in his packaging bio.
- This mold was also used to make Metrotitan and so the ion-pulse rifles would be redecoed to make Metroshot's arms.
