Just had a random thought the other day related to this of how can the world of Remnant create an equivalent of the Russian Mutant.

It can be either Human, Faunus or Grimm but I mostly recommend the last one because:

1. It would be interesting to see a Grimm that is mostly red and white instead of primarily black.
2. The idea of a R.W.B.Y character having Death Factor or something similar as a Semblance is impossible so having Life Absorption would be a better ability by letting Salem work on some dark magic on the Grimm.
3. The tentacles feels like it should belong to Grimms unless there's a Faunus with multiple prehensile limbs more than Sun and Tyrian but the Grimms could remove that biological limitation.

Team LLYD are first years alonng with teams JEWL and RWBY, The teams leader is Lucia Silvertounge, a gambling gal with the devils own luck on her side. Acting as the teams tank is Lin Yuxin who can transform her body in durable sand, she also has a pet bird, Sandy. Yuki Lane is the teams wild card throwing off the enemy with his feminine apperance and his unusual breakdancing style of fighting. And then there's Delilha the teams covert infiltrator, with her ability to chnage into anyone she wants physically although her tail is always there.
