Can I just suggest some possible other characters for your Toa Fikou universe?
A brutish, strong skakdi with a prominent forehead horn (Rhino)
An onu-matoran scientist who unwisely tried to self-repair with the mutagenic effects of Visorak venom, and mutated into a lizard-like Hordika (the Lizard)
A villain with an unusually powerful Mahiki. He obscures his true face with an illusion (Mysterio)
A sentient Makuta virus organism that can jump from host to host and selectively mutate them (Symbiote)
A defective Kranua that mainly gets controlled by other bad guys like a henchman (Sandman)
Also, if you haven't named Pitaka's boss yet, I suggest Jajona.
Most of the villains would be preexisting canon BIONICLE characters, so you got Triglax as Chameleon, Devastator as Sandman, Charger as Rhino, The Shadowed One as Kingpin, etc
People also keep forgetting that I already got Darkness as Venom
Also also @avita-anarchy already suggested Jajona so sorry to say but you’re a bit late there
