Valka using her blaster to burn Lyvon's hair as retaliation for poisoning the captains. Lesson learned: if planning to harm any of the team captains, DO NOT include Layton as one of them.
Barit fighting Tormo by all by himself with only a makeshift armor and a replica weapon. Antola was impressed.
Delma whacking King Altador with a hammer after being called a prissy little faerie.
The battle against the Shadow Warriors could arguably count for most of the prominent characters (excluding Prytariel and Fenny, who both managed to be knocked out)
Notable moments during the battle include Zax and Antola firing a fireball so big it disintegrated an entire truck.
Layton sneaking into Star Corporations completely unarmed after they kidnapped Valka. Not only that, but he knocks a bookcase over the company's leader and proceeds to run out with Valka.
Derlyn grabbing 'Dirty' Navers' sword and threatening to kill him with it if he kills her sister or her sister's teammates. In other words, killing Mirsha and/or any one on the rest of Team Shenkuu will get you killed by Kreludor's team captain
