Cygnus! Hyogen no senshi - S1-E3
Plot hole: The tide of the fight turns when Hyoga revealed that he was never affected by Hydra's poison because nothing can break the defenses of his Cloth. But the claws DO make huge holes, that are then nowhere to be seen by the end of the episode, and yet, a plot point from later in the series, Cloths do not have self repairing abilities - not at that time of the series at least.
Cygnus! Hyogen no senshi - S1-E3
Plot hole: Saori Kido's presentation does not make a lick of sense. Assuming it happens through some odd holographic mechanism never seen before or after, it's day 3 of the tournament, so it appears extravagant that only then she'd start telling the audience what the Galaxian Wars are. Second.it's day 3 of the tournament.and the third match. That means that they have been packing a stadium with dozens of thousands of people, who come over for ONE match that lasts a few minutes. That's a real stretch, to say the least. There's also a minor but kinda funny matter; the way the cameras are shown pointing, the whole world is tuned into an uninterrupted upskirt shot of Saori Kido delivering her solemn speech.
