Yeah, let’s challenge our heroes a little
What if marendar is indeed unable to see holograms made by Takanuva since it recognises them as elemental attacks and they do not arrive to his eyes? then Takanuva could send messages to his team mates witohut marendar knowing
(edit: that wouldn’t work since Marendar would not be able to see any light attacks then. So I would say he can be fooled by holograms, unless he has thermal vision etc)
In my headcanon Toa Nui Nuva already multiplies the powers of his 6 mask powers by six due to Nuva masks ability to share power with those close by
“We are stronger than the sum of our parts, We are one, I am AkaWai Nuva. and your misguided crusade ends here.”
Marendar slashed with all of his speed and might against the Unity of Toa. As his weapon came down, Toa Nui’s mask glowed and Marendar’s weapon only met an after image and air. Marendar looked around but could only see a blurr of color around him.
Marendar hit the ground to attack all the after images at the same time with an energy shockwave. But as his weapons came down, Toa Nui was in front of him. That was last thing Marendar could register before he realised he was miles in the sky after a Destiny crushing punch hit him harder than anything had hit him before. Marendar tried to collect himself but attack had left him breathless so there was little to do when Toa Nui soared next to him and smashed him towards the ground with even more power.
Marendar cleaved the land as he hit the ground leaving a grove after him.
Also, would Marendar know that Matoran can become Toa? Because some Matoran, like Takua, probably helped build him.
I think it was stated somewhere that Marendar can’t sense the innate toa energy inside Matoran.
Definitely he is aware of how Matoran become Toa and Toa become Turaga. He most likely has a lot of information abou the Toa and Matoran.
But he could not know what GBs didn’t know. Matoran universe created a culture and lot of new inventions, creatures and powers. He can’t know about those.
I believe he does not know about Golden armor, or if he does he does not know what powers Tahu has inside him.
