Unless you didn't hear the announcement or saw the preview, but after September 27th, both Space Dandy and Beware the Batman are out of the picture. Space Dandy is ending it's Second Season and somewhat the series and Beware the Batman is out of the picture due to Adult Swim losing the rights to air.
Space Dandy is the most important topic this week on the final episode of the Second Season, Episode 13 of Season 2, 26 overall, and it's the final episode of the series. Weeks ago, a rumor was spread that Space Dandy is ending after Episode 26, but after the end of Episode 25, the episode of Dandy on Trial after being accused of Murder, looks like we're nearing the end of the anime.
Here's the plot of the next episode...
"Dandy had fallen into the hands of the Gogol Empire, and it's up to Meow, QT, Scarlet, and Honey to save him before it's too late."Episode 26 premieres on September 27 at 12:30 on Adult Swim. After September 27, Space Dandy will be moved into another time slot to 3:00am on October 4th, so Hellsing Ultimate had to move a hour earlier.
Space Dandy isn't the only one ending in the Toonami Block after September 27...
Adult Swim now just lost the rights to air Beware the Batman, meaning that after September 27th into 28th, Beware the Batman is off the air for good. So I guess the question is this, is the show cancelled? Don't know, go ask Toonami on the Q&A Tumblr on Sunday 09/28 from 11:30am to 1:00pm.
So Toonami will air the unaired episodes from 2:30am to 6:00am. So just for One Night, Hellsing Ultimate will be on vacation until October 4th. So if you want to catch up before 2:30am Saturday, you might want to do it now.
