D

D was a co-host of Toonami during the TOM 4 era of the block, who mainly appeared in bumpers sending the block to a commercial break or returning to the show after a commercial break.

On March 17, 2007, the base Flowus 3, on an unnamed jungle planet, was introduced as the new broadcasting station of the Toonami block. With the new location also came Flash and D, a pair of new co-hosts to TOM. D is a short, wide robot who has a large wheel, where his legs would be. He has a deep, gravelly voice and sardonic attitude, somewhat reminiscent of former Toonami host Moltar. He was voiced by veteran voice actor Tom Kenny.

For several years, it was unknown exactly what became of D and Flash after Toonami's cancellation, as they were simply seen initiating the permanent shutdown sequence and then walking (or rolling and flying, respectively) away in the final broadcast. However, in the Intruder II companion comic, it was revealed that D, TOM and Flash had a run in with the Intruder at some point in between the cancelation of Toonami in 2008 and its rebirth in 2012. At the end of the comic it was implied that the crew escaped the intruder; however, in The Intruder II, it was implied that they were destroyed by the Intruder.
