*Screens all over RPM City flicker to static, before a very familiar face appeared*
MWAHAHAHAHA!! HELLO AGAIN FELLOW CITIZENS OF RPM CITY!! IT IS I, YOUR FRIENDLY NEIGHBOURHOOD MAD SCIENTIST DR. WILY II!! IT IS TRUE THAT I FAILED PREVIOUSLY... BECAUSE I TAPPED INTO THE WRONG HERITAGE...
NO MATTER!! DURING AN EXPEDITION DEEP INTO THE SOUTHERN BADLANDS, I STUMBLED UPON SOME MYSTICAL STONES... QI STONES... BRIMMING WITH SHEER ORIENTAL POWER... AS WELL AS NUMEROUS RELICS FROM A TIME LONG FORGOTTEN...
IF YOU THINK BOROCKMAN OR VIXY CAN SAVE YOU... WITH MY ANCIENT ZODIAC NUMBERS... OR AZNS FOR SHORT... I DARE THEM TO TRY!! MWAHAHAHAHAHAH!! *static*

Name: Snake
Designation: Robot Master (AZN-006)
Weapon Get: Snake Spear
Other weapons: Snake Buster, Snake Claw
Background: As mentioned above, Snake is one of the 12 relics powered by a Qi Stone that was uncovered deep in the Southern Badlands, each relic being based on one of the 12 animals of the Chinese Zodiac. It seems that these relics were created by a powerful Chinese Emperor named Zhang Hong Weily, as part of his invincible army, and some accompanying records stated that these weapons were fearsome. With modern technology, these Ancient Zodiac Numbers will rise again...
Snake is the sixth of the AZNs... Yet the first to be encountered? His general design seems to be based on snake jars, and how a snake could strike at any moment. As such, his Snake Spear is feared, striking from nowhere (demostrated in his second sprite). His Snake Buster can shoot off snake-shaped projectiles, while his Snake Claw can slash from any distance.
Character: Sssssssssssssssssssssssss
Weakness: ???
You get... SNAKE SPEAR!!

You get this weapon from defeating Snake. The Snake Spear can only be used if an enemy is on-screen, if not, no weapon will shoot out. Once shot, most minor enemies will be destroyed in one hit.
