Giant Robo/Awesome

More like a Crowning Series of Crazy Awesome, but Robo's entrance is particularly awesome.
In the second episode, Chief Chuujou is preparing to evacuate, then self-destruct the base, while he battles the two invaders. But he hears a voice asking him to wait - Issei and Youshi are on their way! They can't quite get there in time, but make up for it by (quickly!) declaring to each other that they'll stop the Magnificent Ten, and do so with magic. ...While "NO MERCY OF THE BUDDHA FOR THE WICKED" appears on the screen in brush-written kanji. All while "Rush! Issei and Youshi!" (an Eastern-style arrangement of "How The West Was Won") plays in the background.
Chief... no, "Silent Chuujou" of the Heavenly Nine stands up to the Monster Sphere at the end of episode 6. He takes a few practice punches and rockets up to it, intending to punch it (and himself - it's a double-edged blade and he's feeling guilty about not being able to do anything up until now) to oblivion.
The whole of Episode 7. Starting at about the point where Daisaku reaffirms his belief in his father and takes off towards a faraway Giant Robo. EVERY living Interpol character (and a couple of dead ones) help him get there. A couple of Not Quite Dead guys even show up. We learn that Robo carries enough ordnance to level a city. Most importantly: Dr. Von Fogler was a good guy all along, and when the three tubes are put together, they purge a dangerous substance caused by the Shizuma drives from the atmosphere and save the world.
