Hey, Iron Knuckle!
Some improvements that I would make would be using proper English and spelling, but that's not really a big problem!
Also, I've noticed that you make other characters do things sometimes. This is called godmodding, and is usually frowned upon. You can't make another character in a RP do or say something that they, themselves did not do.
Even if nobody is that character.
For example, in a RP, this is godmoding:
Princess Zelda walked up to Link and said, "I think the Gorons are peaceful."
Link replied, "I do too."
There's really simple ways to avoid doing things like that though, like this:
Princess Zelda walked up to Link and said, "I think the Gorons are peaceful."
She anxiously waited his reply.
Other than that, your RPing is spot on. I love the head-canon you made for the Iron Knuckles! Very well thought out.
