Beowulf and Cloud were far more useful against Altima than Orlandu. Beowulf's Drain consistently does over 500 points of damage compared to Orlandu's 2-300, and Cloud's Climhazzard eventually is assured 999 damage. I've never seen any of Altima's forms do anything because, quite frankly, I've never seen Altima attack. Altima would have been harder without such piss-poor speed, I think.
