ok, so ligers are usually much bigger than tigers or lions. check.
this things mother is a liger, and barring any health or biological defects should be healthy, but isn't able to provide enough milk to keep the genetic abomination satisfied.
is this thing going to grow up to be 20ft long? and if it does, how many times do you have to re-ligerize a liger to get something big enough to populate an evil genius's island? And what color battle armor would look best?
