This was a semi trick question, as there are two answers I would accept. The Flame eater with 4 balloons/bombs, or Hidon with his 4 Hidonites/Erebuses, for a total of 5 targets. Even if you managed to get the Airforce to deply a speck/bit, only 4 targets. the waterfall battle doesn't have the typical boss BGM, and also tops at three fish at a time. 1 point for to blackmage_nuke, espritduo, Jiro and Flying Mullet.

Question 10
Name an attack that enemies can use to eject (remove) a character from Battle. You can get two points if you name 2 different attacks, 0 points will be given if you say an attack that is incorrect, so there is a risk factor for this bonus
