Yes, expanded version of KXE. But… name changed from KXE to KNX. (Backstory: When KNX was 4, he had another name, Kianex. He had a 20-year-old mom, a 23-year-old dad, and 2 brothers. When he turned 18, he was used for experimental purposes. And after the tests, he gained the claw you see on his hand. During the Node Spawn attack, his family died, except one of his brothers. They traveled together to avenge their lost family members. [BTW, his brother is 16.] Later in their journey, they lost each other in the void, and Kainex, now known as KNX, kept journeying alone.) Personality: Quiet and childish, he is serious when he needs to be.
Age: He is 20 now.
Favorite color: Red
Hobby(ies): Karate.

OOF.

Ok.

It’s not that good fam.

It’s only defining feature is his arm, which won’t do in the Stick Nodes community.

Maybe you could give him medievel armor, and make him a cyclops with a mythical eye in his gauntlet. Making this gauntlet cursed, as the more he uses it, the blinder his right eye becomes, only having these effects reversed by finding blood for the talons.

Design him with his personality in mind, if he’s quiet and reserved (Like you said he was) put him in a dark cloak, with a few plates of armor so the gauntlet isn’t too out of place.
Give him black or dark brown hair (Or no hair, if you want)
Give him a real emo look, put some eye shadow on one of his eyes or something.

This figure just isn’t very good, it’s just a base fig with a arm, that isn’t very unique.

I give it an F.

when making a character try to plan it out before actually creating it, this way you can be more unique and get more than a base fig, just some advice.
