The Earthquake Warriors have villains they need to fight and innocents they need to save. Here's a whole bunch of them starting with the fox in the red sweater and ending with the big guy on the right.

Gunner Fox: They wield a fairly strong gun that does Piercing Damage.
Boxer Fox: Absolutely cannot hurt you. Not threatening.
Slashy Slither: Has a knife, can deal slashing and piercing damage. Slashing works better on harder bellies.
Big Brute: Fights using his fists to deal bludgeon damage. Harder, more pact bellies like Fang and Toasty are weak to Bludgeoning but strong against piercing, while softer bellies are the opposite.
Hostages 1-4: Okay, these guys are not enemies. In fact, harming them will cause the whole party to be inflicted with Grief, which lowers their stats and causes them to take damage. Instead, kill the badguys without harming the hostages for a nice cash bonus.
THRUMP!: This guy is the boss of level one. One of the four members of the Evil Earthquake Assassins, and your first true test. He has megaton punches that deal bludgeoning damage as well as a shock-antenna (Think Buyon/Jiggler) that deals lightning damage, something Ricky has no problem dealing with, but Fang abhors.
