This is a set of three Hexa Gear models: Agni Rage, Governor Parapawn Expander, and Pump Up Expander (with Gatling gun). The small Expander is missing the pipe part on its back. → Found it. The Expander, despite being the most powerful unit among the Parapawns, felt somewhat unconvincing in terms of its setting as a product. (See the photos for size comparison with Armor Type and Zoanthrops.) The Pump Up version, released later, had the convincing size that the old version lacked. Although it was a bit too large, it could create an overwhelming boss presence just by placing it among many Armor Types. The strongest Hexa Gear that the Expander pilots is Agni Rage. Using the Bolt Rex series frame, it allows you to feel the systematic evolution of Hexa Gear, and it was a unique final boss, a dragon-type Hexa Gear that had never existed before. Although it has been surpassed in size by giants like Nedia Rivers, I think that around the 2nd anniversary of Hexa Gear, the big bosses were either Agni Rage or Gigantic Arms' Ultimate Guardian. I think that "the final boss of Hexa Gear Season 1" is a fitting description for Agni Rage. In fact, the product development after Agni Rage focused on the old generation, such as Early Governors, related vehicles, and the Bulk Arm series. Personally, I feel that the appearance of Brocade IB and Bulk Arm λ pushed the Hexa Gear story forward after Agni Rage. In other words, I think Agni Rage has enough presence to be a turning point in the story. And just as the Hexa Gear story cannot be separated from the Governors, the Expanders also show a great presence in the story.
