 * At first, he shows contempt for Ishiyama's students and seeks a confrontation with Oga in the first opportunity. At the point, Oga's thoughts are of forcing baby Beel on him; knowing that fighting back means expulsion, he decides to take Alex' punches at first, while testing him with trivia questions in order to show baby Beel that he is not only strong but clever, with comic effect.
 * Alex is strong enough to defeat the MK5 with ease. However, he is no match for Oga: his punches fail to knock him out at first; later, Oga easily evades them and even stops one with his hand. When he finally evokes a reaction from Oga, the latter deals him a defeat similar to the ones Alex is known to deal to others: a one-hit knockout.
