Space Phantvern

Space Phantvern is a wyvern-shaped creature with the head of an elephant. While being developed, some scientists messed it up and accidently inserted Umbrantium on its DNA. Luckily, it only made it stronger and reduced its agressiveness, for some reason. It's one of Magna Weegeepede main summons, along with KeaRex.

Story
It was the first Chimera to be created in the SCP and since then...well...it has never left the place. It is trapped inside a very resistant cell and is fed periodically.

Combat
Due to being made out of Umbrantium, it's very heavy and can't fly, despite the wings. It can shoot beams of altered dark energy, which are very dense and can easily break someone's bones. It can also run over someone and cause a lot of damage.
