It's said that martial artists are wise in their old age, giving them something mentally to make up for what they've lost physically over the year Haschel has long since proven to be an exception to this rule. His actions in the fight did nothing to dispel this, as he merely prepared for a physical contest.
When Zidane came trotting in as the ref, Haschel didn't even so much as plan for anything else but an honest fight. Why would a ref w ho he had never battled interfere? That made Zidane's use of Mini especially galling- well, for as long as he was alive, which was the few seconds it took for Jade to cast Meteor Swarm and bring down a mountain of rocks on his tiny head.
