Chanbara is the only option (the story behind Reptilia Squad Multiplayer)

The main protagonist of this story is Lenin Grossekomodowaran.

He's an enormous, heavily muscled anthropomorphic lizard, an albino Komodo dragon.

His iconic clothing is an ō-yoroi named El Garañon Macabro, which more resembles a lorica segmentata than actual samurai armor. Furthermore, his daisho is actually a pair of dotanuki and o-wakizashi swords, both with thicker blades than normal.

This episode of Lenin's saga takes place during 8th season, more specifically as a side-story, and involves the albino Komodo dragon fighting the Heroes of Rio de Janeiro.

They attack with a variety of military rifles, machineguns and grenade launchers (not to mention rocket launchers), as well as machetes, ninjatō, uchigatana, katana, yanmaodao, liuyedao, miaodao and, occasionally, niuweidao.

Furthermore, they are all equipped with cybernetic exoskeletons (Combat Suits) conceived to fight the monsters 'on equal terms'. Also and not surprisingly, their cybernetic exoskeletons are equipped with powerful explosive charges, which are intended to be used as self-destruct devices; once activated, the self-destruct device takes a few seconds to charge, and it begins a relatively short countdown (indicated on the display); such devices are built into the Combat Suits themselves, being activated Predator-style.

Curiously or not, this story is related to "Reptilia Squad Multiplayer", one of the games planned by Swordsdragon himself.
