Owl-Bears, Half by Half

So, these variants are for all our favourite chimeric, avian and ursine combo beasts. I find it funny that as long as Owlbears have existed, there's never been anything like this [that I've seen at least].
The stats are somewhat tailored for 5th ed D&D, don't tell anyone, there's also nothing stopping you using the principles for abilities in other systems. Its not like I've statted them out robustly anyway!
[Note to self: Maybe I should.]
