Are flesh worms and serpentipedes related species?

[ax34]

They looks a bit similar, they usually occur together (even when you play Doom community pwads with Freedoom), so i ask.

See. According to the lore of freedoom which was posted in freedooms official discord server 

Flesh worm and serpentipedes are infact related.

Both creatures are native of the planet horizon 

the reason horizon has hellish themes that's because agm (uac counterpart) was experimenting in the native species so the aliens took the help of the hell to make a invasion to agm base in Pluto (e1 takes place in Pluto) and our marine protagonist also was getting experimented on so he escaped Pluto and the aliens already took over in the astroid 

Ceres (e2 takes place in Ceres) our marine discovers 2 new aliens 

1. The trilobite (this aliens genes were distorted and make in this)

And assualt tripod and in the e3 we know it takes place in the alien planet horizon. And e4 also know as double impact that takes place in one of neptunes moons
