Technically everything is flammable given enough fuel. But you do not think the goop is any more flammable than, say, concrete.
Meanwhile, Kaito finished setting up his Gauss and drawn the beat on the big thing.. taking a good, careful aim, clenched his stomach and squeezes the trigger.
There was a low whine as the weapon supercharges the metal stake with the power that a small family of four uses for a week into a metal stake, several safety mechanisms releases and the final activation sends the stake out with speed that immediately broke several sound barriers.
The blast sent every single nearby Spiderbeetles flying and splattering against hard surfaces while everyone's suits whine from the shockwave trying it's best at liquefying your insides. Vigil's suit in particular shifted slightly as his gyro-stabilizer was working at half-efficiency. Slime, goo and gore rippled like a wave from the launch, the Stake was there in less than a heartbeat.
Kaito Gauss: 26
Then you watch as the stake hits that large thing at an angle and ricochets off of it's angular armor with a deafening metalic PING! and flies off into the far wall with a kinetic explosion that have decimated the mountain range of Mars.
And combat was on, that thing bursts out from the pool, revealing it's full form as gore and offal drips off of it, large.. man-sized legs pushing it forward, the saw-like serated teeth along it's spine and long tail whipping wildly as it begin rushing towards the Nearest target, Danh.
It makes a terrifying screech as it charges, it's black carapace shiny from all the gore coating it, it's size.. Even excluding the tail, it's still roughly the size of a damned Main Battle Tank.
And holy sweet jumping baby jebus it's fast, oh god it's fast. Oh shit it runs really fast.
