After Nukus was brought to life, he brought out 14 Beetleborgs monsters (consisting of Graxxis, LottaMuggs, Garganturat, Amphead, Cyber-Serpent, Dicehead, Porkasaurus, Mucant, Crimson Creep, Unctuous, Super Grenade Guy, Kombat Knat, Hypnomaniac, and Evil Eye) from their comic issues to battle the Beetleborgs.
During the battle, a few monsters (namely Kombat Knat and Dicehead) were sent back again by the Beetleborgs via their Sonic Lasers and the rest were wiped out by the A.V.s, but then Nukus fused the energies of every one of Vexor's monsters with the energies of the Beetleborgs' blaster powers to create one massive creature called Borgslayer, a composite monster that resembled Hypnomaniac with many monster faces on him (among which were the faces of Vexor's brief second form, Shadowborg, Green Cannon Machine, LottaMuggs, Malavex, Furocious, Kombat Knat, Super Grenade Guy, Super Noxic, Wingar, Goldex, Evil Eye, and some unidentified monsters such as an alien-looking mutant and a gold-faced human-like demon).
The only way to defeat Borgslayer was for the Beetleborgs to triangulate their firepower. By doing so, Borgslayer was finished and the residual energy from the explosion managed to suck all the Magnavores and Vexor back into the comic book world. This enabled Nukus to become the new villain for the Beetleborgs.
- When used in US footage, Borgslayer was seen without it's extra arms.
- This the first US footage appearance of Goldex and Wingar, albeit their heads only.
- Some of the monsters seen on Borgslayer were not brought out, during the battle before Borgslayer's creation, though were used previously in the series. Other unfamiliar monsters might be from the comic books, having never been released by the Magnavores, during the series. Nukus may have tapped into them, or perhaps the Magnavores released them to battle the Borgs, off-screen.
