Or one will thinks so from looking at the host. From what we could analyzed from the test results; Test Subject 08 was remarkably adaptive to the host's natural inclination for spears. once again, Species XX121, has proven that no matter how ineffective or incompetent the original host was, it will be born a perfect killer.

Log 22390 - Dr.Value WW Xenobiologist - Employee Number 800869

The log was found on Dr.Value's corpse several days ago. He appeared to have been terminated by his latest creation. The cause of his death was an expertly thrown spear that impacted into his heart; the weapon in question was a torn piece of metal piping that had been crudely crimped and sharpen at its ends. We where unable to find the Test Subject 08, even with these clams.

All credit goes to  Valsalia for crating this species that birthed this horror; also consider visiting the  ZheEnclave for more great Yinglet fanart.
