Algolians

Criminals stole a deadly virus that transformed anyone (specifically in MariGold's home planet Leslie) infected into living robotic slaves, in order to sell the vaccine for it at a high price, once they release it. They themselves are living robots, known collectively as "Gas Drinkers". Their names are puns on alcholic beverages. They all had both human and robotic modes.

KillerTank
Vulgar escaped in a teleportation device and went back to planet Leslie. The Dekaranger followed them and they fought him as he piloted the KillerTank. The body above can rotate around the tank wheels. DekaBreak came in the BlastBuggy to help them. They then faced a bunch of Killer Tanks. They lined up in a line and were destroyed by DekaRanger Robo Full Blast Custom.
