Alien- Rhino Charge

  The creature pauses. It turns its head slowly, like it’s following the sound.

  A beast the size of an Earth rhino bursts out of the greenery behind it, bellowing a challenge in the instant before it slams into the creature. It has a whole head of spreading horns, and a maw that’s more like a beak, unfolding in floral horror when it goes to bite. I’ve seen this thing before. Mom calls them “Zagreus hippos,” a kind of local omnivore that spends most of its time wallowing in shallow wetlands.
...

The creature is occupied with the hippo, the two of them rolling over and over again, the hippo bellowing and the creature hissing in terrible fury. It has speed and vicious natural weaponry on its side, while the hippo has a hide designed to protect it from both the lion-worms and the huge reptilian predators that lurk in the wetland mud; the hippo is already losing, although it doesn’t know it yet, but digging deep enough into its flesh for the hippo to bleed out is going to take time. Not much time. Enough.
