Despite his inability to defeat Blader, Cannon Thunderbird was able to protect Hydra from the Magia and fight them off, even detransforming one of them. Especially notable because he accomplished this by shooting the tiny magical crystal in her wand, with a scopeless revolver, as he was running in the opposite direction, looking over his shoulder and shooting at a moving, airborne target, nevermind under severe stress and enemy fire.
Episode 4 finally shows why Akashic is the leader of Agastia when she defeats a monster from another organization with a single hit, tearing it to pieces.
The final episode, which is an all-out war against Zet Arc and all the previous characters return for the finale.
Also Kuroitsu getting her own Henshin Villain form, complete with awesome Transformation Sequence. Of course, this show being what it is, she’s locked into it until the MDD can get the bugs out.
