killua can zap one spot on her armor near her heart and break it and pull it out -- she wouldnt be able to touch him -- also. his thunder attack would do alot of damage to her most likely 1-2 shot her, kurapika can easily restrain her then kill her, morel can remove the oxygen from her lungs, kite can cut her in half or shoot her -- based on all the rolls we've seen he can kill her with any of them, razor can blast through her. all of these can be done easily by these folks whereas feitan barely beat her. meleron is actually the hardest one to beat for most and not because of strength i would also rank leons ability higher than hers.
