"Max says he has an idea on how to remove the
bracelet and takes Verdona to a smelting plant. He
attempts to remove the bracelet with a pair of steel
clippers, but the bracelet proves to be made of an
incredibly dense material. The Synthroid catches up
to the pair and Max attempts to stop it. After
sustaining some damage, it reveals that it can
automatically repair itself of all injuries. It captures
Verdona and leaves to repair its ship."
