Ultraman Trigger: New Generation Tiga Episode 7 - "Inter Universe"
Dark Giants' story was pretty much serious in The Final Odyssey. But Trigger's Dark Giants are part of TV Series. They can't be always serious. It's good to see that they have some funny and interesting human-like aspects.
Trigger was also once a Dark Giant. But he found the light within him. If Trigger can come to the good side, then why not Dark Giants? I would to see a redemption arc.
