The Lancers split up into two groups during the ambush , and Sanders told his students not to worry as it was part of the scenario and asked them how would they handle the situation . He was displeased when all of their plans focused on destroying them instead of capturing them , as were the orders , and he told them to watch carefully how to carry out a capture operation . Yuya ' s group were captured , and Sanders picked Ted , Ethan , Bernie , Jacob , and Emma to put their lives on the line in a Survival Duel against the five Lancers . ( In the Dub , he instead asked for five of his students to volunteer and go up against the five Lancers in a Survival Duel ) . When the Lancers were brought to the arena , Sanders told them they would battle his five elite students until there was only one man standing . He told them the Survival Duel would create the ultimate soldier and the losers would become cards . He activated the Field Spell " Predaprimal Jungle " and started the Survival Duel . He told the rest of the students to burn this Duel into eyes as they would witness the birth of the ultimate soldier . One of the students was quickly defeated , and Sanders realized that this was the work of the Battle Beast and commented how he was as haphazard as ever , though he reassured himself that the elites would definitely make it . However , Emma and Jacob were defeated , and Sanders was outraged that his top elites were wiped out and couldn ' t surpass the Battle Beast . Crow Hogan revealed the Battle Beast ' s identity , and Sanders told everyone that this was the strongest Battle Beast that he had grown , BB .

He used " Test Fusion " to Fusion Summon " Gladiator Beast Tamer Editor " and used the effect of " Tamer Editor " to Special Summon " Gladiator Beast Andabata " from Battle Beast ' s Extra Deck to his field . He told Battle Beast to fight freely now and show his strength and viciousness to the enemy as it was a direct order from the Professor to eliminate the Lancers ; especially Yuya Sakaki . He tried to use the second effect of " Tamer Editor " to destroy " Scarlight Red Dragon Archfiend " , but Jack prevented it with " Red Armor " . Instead he attacked Yuya directly and told Battle Beast to prevent him from getting an Action Card , but the Battle Beast simply stood there in shock . Yuya dodged the attack with " Evasion " , and Sanders yelled at Battle Beast for not following orders , stating the superior officer ' s orders were absolute on the battlefield . He told the rest of his students to engrave it into their hearts , as absolute obedience was his cardinal rule . The Battle Beast used " Gladiator Beast Assault Fort " to protect himself , and Sanders told him to bury Yuya and Jack , but yelled at him again for ignoring orders again and threatened to seal him into a card . To his utter shock , the Battle Beast used the effect of " Tamer Editor " to destroy itself . He is then defeated and got mad at Battle Beast for attacking him too . He listened to Yuya and Battle Beast ' s talk about their similarities and told Battle Beast to seal him because he can teach his students how harsh a real battle can be .

He then told Battle Beast to seal him and eliminate Yuya as it is the Professor ' s order and told him that he won ' t survive if he fails . When Battle Beast ' s " Forts " failed , Sanders was angry that Battle Beast failed to win the Duel with his trump card . Sanders called Yuya an idiot for destroying his monsters due to the effect of " Great Fortress " and he ' ll meet his end as well .

Sanders told Yuya that the Professor ' s next assassin will send him to his doom as his students take him away . Deck . Like Battle Beast , Sanders runs a " Gladiator Beast " Deck , which is focused more on traditional Fusion Summon ing , and it includes the " Test " support monsters .
