Jay:
He's an average stickman who was around during the war between the stickmen and octo-sticks. He hasn't been paying attention to the news lately about what the octo-sticks were doing, but one day, while hanging out with his friends, he got to see the true horror the octo-sticks brought to the stickmen as a crew of 10 armed octo-sticks came from the sky and kidnapped his friends. Jay was able to escape, but since that day he vowed to destroy the octo-sticks and any other empires that opposed the stickmen. After escaping, he traveled to Stickmania, and went to see Redi himself. Jay said to Redi that he wanted to become a soldier, and use the new technology Redi has developed so he can defeat the octo-sticks. Redi gave him a lot of things, among them being a mech suit with a laser gun, that is what his main weapon is. He is one of the best soldiers of the empire nowadays.

SN:
Not much is known about this mysterious stickman, but his story is similar to Jay's. His parents are fighting in a war against Beldum at this time, but one of his parents didn't make it out alive from this war, and didn't have a ressurection cube! After hearing about this, he went on a quest for revenge. SN found many powerful gems, and using these he made 2 katanas which can teleport to him, and a suit that makes no noise when moving. He is rarely ever seen, but whenever he is needed, he teleports behind the enemy to annihilate it. One report of seeing SN, was during the stickman and octo-stick war, and SN took out an entire fleet of octo-sticks, he noticed the small group of fighter jets did not have a chance against that fleet, and struck back.

Nice
