On midnight of April 1, 2012, just past Toonami's 15th anniversary, Adult Swim, which generally changes its programming for April Fools' Day, began to play The Room (as they had done the past several years). The scene then switched to T.O.M. (in his third incarnation) aboard the Absolution, greeting the viewers while commenting that it is April Fools' Day, before introducing that week's scheduled episode of Bleach. The Toonami-related programming and bumpers continued throughout the night, featuring Dragon Ball Z, Mobile Suit Gundam Wing, Tenchi Muyo! Ryo-Ohki, Outlaw Star, The Big O season 1, YuYu Hakusho, Blue Submarine No. 6, Trigun, Astro Boy, and Gigantor. T.O.M. also presented a review of Mass Effect 3 and promoted the recent DVD releases of the series featured.
The following day, Adult Swim posted a message to their Twitter page, simply stating, "Want it back? Let us know. #BringBackToonami".Adult Swim has decided to bring Toonami back on Television On April 7 Toonami will premiere on Television on Adult Swim 11:00
