As a fortress made human...or whatever it is the Wiseman are, anyways (even they aren't quite clear on that point)...Berle is quite the difficult man to take down. His high natural defense, elemental resistance and constitution would make many fighters do a double take; add in the invincibility move MetaGuard and very few can hope to outlast Berle. The Wiseman may not be the most damaging of Godlikes, but with his excellent staying power, he has a good chance of running Terra out of MP and maybe even mystic energy, leaving her bereft of damage and healing before his mighty Meta Cancellation spells her doom. And since Terra isn’t exactly the soul of speed, Berle’s rapid sword slashes should be able to run rings around the half-Esper, making it even harder for her to keep up.
