Just like Bionicle, Ninjago characters make use of elemental powers. The exact functions of the elemental powers may differ, but it’s the same principle. Pretty much every Ninjago character has a Bionicle counterpart.
Kai (fire) -> Tahu, Lhikan, Vakama, Jaller, Ackar (to an extent)
Cole (earth/maybe stone) -> Onua, Whenua, Nuparu, and possibly Pohatu, Onewa, and Hewkii
Jay (lightning) -> the Toa Inika
Zane (ice) -> Kopaka, Nuju, Matoro
Nya (water) -> Gali, Nokama, Hahli, Kiina (to an extent)
Lloyd’s power is a little more vague. Story-wise, he’s comparable to Takanuva, but his power is said to be “energy.” He’s also shown to control fire, ice, earth, and lightning. Unfortunately, I can’t think of a Bionicle equivalent for Lloyd’s “energy” power, except MAYBE plasma.
But for the other comparisons, who is more powerful? With Lightning, it’s an easy choice. The Toa Inika weren’t full-on lightning wielders; lightning was intertwined with their main elemental power, whereas Jay’s elemental power was full-on lightning. Therefore, I think Jay wins that round. Earth…maybe Cole would win. Regardless of where you stand on the Earth Vs. Stone debate in the Bionicle community, Cole seems to possess both powers; chances are, he’ll win that round. But with Water, Fire, and Ice, it’s a little harder. Off the top of my head, the only major feat from any of those was when Nya manipulated a whole wave of water to drown the Preeminent. And Zane creating the Blizzard Samurai doesn’t count, because he had the Scroll of Forbidden Spinjitzu. I’m only talking about pure elemental powers here.
What do you guys think?
