Damage, damage, damage. Electricity will still work on him, buying a couple seconds, so Electro Bolt and Electric Buck are good. I had maximum ammo for the Chemical Thrower and the Grenade Launcher as well, because they do a lot of damage. Stay away from him, max out ammo and supplies for health and EVE, and have nice Plasmids.
(Enrage, Hypnotize Big Daddy, Security Bullseye and Cyclone Trap are all but useless.)
