Autobot Action Master and walking computer Mainframe carries a vibro pulverizer, which can combine with his robotic partner Push-Button to form a powerful proton rifle.

Toys

The Transformers

• Mainframe (Action Master, 1990)
  • Accessories: vibro pulverizer, Push-Button partner

The Transformers Mainframe came with a blue vibro pulverizer that he could hold, or which could combine with Push-Button to form a proton rifle.

Notes

• Similarly to many of the other Action Masters' Dreamwave More than Meets the Eye profiles, Mainframe's vibro pulverizer was replaced with a double-barreled proton gun—essentially just a smaller version of Push-Button's weapon mode. The most likely reason for this is that the More than Meets the Eye writers' reference materials did not include the toy's instructions where both weapons were named, and the profile was based on the packaging bio which only made reference to Push-Button's proton rifle mode.
