How about a monkey with transformation ability to copy anyone it has seen with the only restriction being not being able to copy someone of higher realms realm. So he can copy higher realm beings just not their realm. But of course it has the effects of showing a higher realm of those of lower realms he copies and utilising their skills and traits at those realms. While it's hidden bloodline being All-encompassing Monkey King, with no restrictions beside summoners mana capacity. Fight fire with fire?
