The Ivy +YX is a variation of the Plant 43 (colloquially known as "Ivy") developed by Umbrella
This B.O.W. variant was manufactured by Umbrella for sale on the black market. Javier Hidalgo was one of the customers that acquired these creatures.
While similar in appearance to Plant 43, this Ivy has a much more humanoid appearance particularly in the lower portion of its body. Its methods of attack are also identical to Plant 43. As a result of the genetic combination of a human gene, it has legs resembling those of a human granting it much more advanced movement ability over the original Ivy. These legs allow it to move faster than the average Ivy, removing the lack of mobility bottleneck which plagued the original subjects.
