Reynolds is the lead demolition officer of Charon Industries. He often acts as a squad leader whenever Kowalski isn't in charge, having served in the UNSC alongside him. He grew up as the eldest sibling, and became an action movie enthusiast. This interest would lead him to drop out of school and move on to work in a junkyard. When a car had exploded at the workplace, Reynolds felt that he found his calling, joining the UNSC and taking whatever opportunity would let him blow things up.

His behavior soon came to the attention of superiors and it was seeming like all was lost for Reynolds, but Charon Industries offered him a position. In taking this, he knew that finally he would be able to take place in the battles he had always wanted.

Reynolds can be rather blunt and dismissive, feeling he is always in the right. In his team, he is noted to be a bit of a loudmouth, usually cracking jokes or making declarations of war, and he always loves a party. In truth, there is nothing he wouldn't do for his friends, despite the words that come out of his mouth.
