Who said anything about pulling abilities out of a hat?
Emarcee is a defined character, with a defined power set.
Well could you list them?
It's quite a short list, actually.
His armor has several devices embedded inside that interface with his body, granting him a couple of Matoran Universe powers. These include: lightning, magnetism, telekinesis, teleportation, and light.
The armor itself is made of protosteel, a substance that has only ever been known to break under extreme weight, concentrated amounts of energy and heat, and other objects made of protosteel.
The helm (as you can see on my profile pic) looks like the tryna, but it's not, trust me
What the helm CAN do is its lens can display different spectrums of light to Emarcee, e.g. infrared, x-rays, etc.
It is worth noting he can use telekinesis on himself quite adeptly, and as a result can fly at very fast speeds.
It is also worth noting this is originally a BIONICLE OC so uh... yeah.
So there, I'm not just pulling all this out of thin air. This is a character I've had for years one that I've both RPed with and written for in the past
What exactly is OP about all this? Plenty of superheroes have telekinetic abilities that are just as if not much more deadly.
The fact that you have an ability for everything.
I could say the same thing about Superman. He has an ability for everything, and the only thing that threatens him are green rocks!
In contrast, Emarcee is not invincible without being in contact with some strange substance. Protosteel is a strong but breakable substance. You just need to know what breaks it, and catch Emarcee off-guard.
