|Black Baby Beel|
Being an exact replica of the original Baby Beel, not many changes of appearance are made. However, Black Baby Beel is coloured in a black and grey tone and has no visible eyes. He retains Baby Beel's trademark hair, pacifier and is also nude.
Like Baby Beel, he speaks in nonsensical babbling and the typical baby language, however since he is a demon radio carbon copy, his voice has a distorted volume to it. Like Baby Beel, has a large curiosity of things and ends up chasing a rabbit during a training session with Oga his opponent. He, like Beel also gets bored easily, Zenjuro attempted to entertain him by buying him a Shougi set, but Black Baby Beel soon got bored with it.
Saint Saint X'mas ArcEdit
During the Saint Saint X'mas competition, Black Baby Beel joins Saotome and Ikaruga while they are competing, hiding within a wool hat that Saotome wears to disguise himself. When the two adults are about to face off against Oga and Hilda, Saotome loosens his hat to show that Black Baby Beel is inside. Later, Black Baby Beel and Baby Beel meet each other again and start comically fighting one another atop their respective male figures' heads; while they fight, Black Baby Beel slaps Baby Beel and sends him flying backwards. Afterwards, both infants participate in the subsequent match with their respective pairs, neither of which doing much aside from observe while clinging to the male figure's upper body.
Powers & AbilitiesEdit
Being the exact same as Baby Beel, Black Baby Beel simply possesses the Demon Lord's hidden potential using it at full power. He is shown to be very powerful being able to headbutt Oga into a boulder.
- 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 tape 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.
After training in the Mapputatsu Mountains, Saotome had expected Oga to defeat Black Baby Beel. Since he wasn't defeated and still existed, Saotome couldn't find it in him to destory him or leave him to live into the mountains so he decided to take him home with him. Saotome acts as his caregiver and keeps him under his teachers desk.
Being the direct subject he was created from, Black Baby Beel shows some fondness to 'himself'. However, both show a rivalry due to one instance of them arguing for milk Oga was preparing (resulting in the discovery of Super Milk Time). When Saotome reveals he had decided to keep Black Baby Beel, Black Baby Beel comically grabs Baby Beel and tosses him over.
In the anime episode Black Baby Beel Has Grown, Himekawa 'kidnaps' him due to his striking resemblance to an old statue his great-great grandfather had found which gave him good fortune. Due to its disappearance the Himekawa family grieved its loss, Himekawa believed Black Baby Beel to be the statue and decided to keep him. Black Baby Beel's feelings to Himekawa seem to be mutual as he is shown to hand some luck over to him.
