I would say a clear definition of the power is in order
on a personal basis I would say batman should get the adaptive if a character like shikamaru has it and he just adapts to situations by battle strategy
Adaptive is a generalized word. Normal humans can adapt to the enviroment changes such as i.e. putting on a jacket when it gets cold.
Batman does not have any superpowers yet we list other abilities like stamina and insanley rich into superpowers (well the superpower list should be changed to attribute list anyway)
If we agree that adapt shouldnt be on the list since its too much of a generalization and you want to change the category to natural biological adaptation then thats different untill then batman should get the ability
I am going by the definition that would be given in the dictionary
