Techniques

 * Black Baby Beel Cry: Just like Baby Beel, Black Baby Beel retains his crybaby personality. After getting his head stuck in a hole in a tree, He got upset and proceeded to cry. This cry retains the similar electric element of Baby Beel's, but at a much larger scale, so large it burns the tree and creates a large chasm in the ground.
 * Flight: In desperation to escape from Oga and to locate the wayward rabbit, Black Baby Beel revealed he had the ability to fly by flying over the chasm he had created before.
 * Tape side change: After a given set of time Black Baby Beel requires to "change tape sides". Since he is an entity created by a radio he possesses the characteristics of being a 'tape'. 'Side A' shows he is considerably weaker, but 'Side B' shows him at full power.
 * Lord of Flies form: Baby Beel's true form in battle harnessed first hand by Black Baby Beel. After his apparent capture from Oga, he "Switches tap sides" and takes this form. However, Oga easily 'defeats' him by simply ignoring him, leading Black Baby Beel throwing a confused tantrum and eventually giving up.
