Dukamu

Dark Universe Kakamu is the version of Kakamu from the Dark Universe. As with most other Dark Universe inhabitants, he is bent on conquest and destruction.

He arrived in the BZPB Multiverse through a portal at Side 8, and teleported away when the giant self-destructed. He met Vorahk-Kah in one of the pocket dimensions that he travels through. He wasn't supposed to be there, so he stabbed him and crushed his head under his foot.

Upon hearing of the Nakamura, he went to it but found that it was crashed on the Icy Planet. Immediately he built some kind of gun from parts from the control panel, and revealed to the audience that the DU version of Serecio showed him how to make it, and he killed him with it.

He went on a rampage with his new weapon, randomly blasting people. Using his portal gun, he travelled to Vassilan, but was intercepted by Le Chiffre (DU). They fought for a while, but DUK, getting bored, portalled to the pocket dimension that is used as one of the gateways from the DU to the BZPB Multiverse. There he met Kakamu (SMU) and they beamed to a black rocky planet, to arm themselves.

Much later, it was revealed that they had been building a direct portal to the Dark Universe to use instead of pocket dimensions. This was so they could bring Monarch through safely, as most of the dimensional passages to the DU had been closed off at that time. Kakamu greeted Monarch, and told him that they were at "stage six" of "the plan". Monarch also met SMK while there, who accidentally revealed that the Shattered Mirror Universe was not a splinter timeline of the Dark Universe, and was in fact completely independent. Not wishing to work with someone not from their universe, Monarch destroyed SMK's armour in front of DUK and exiled his antidermis to the UG. DUK understood that he did what had to be done, as he wasn't aware that the SMU was completely different from the DU until that point. Kakamu then instructed Monarch to repopulate the UG, which he did by abducting several characters from across the multiverse.
