Are there any bug battles that have more than three enemies in a line-up?

Was organizing a squad to go from most enemies hit by skill (all) to least number of enemies hit by skills (one). It struck me when it came to the skills that hit three enemies that I don"t recall fighting more than three enemies in a single battle. I'm only at stage 13 (get sidetracked by events, whale ship, etc) so maybe later stages you face 4+ enemies in a battle. So in effect they are also hit all enemies basically.
