This is a really good post. My guardians have lore tied to their creation and style. Here it is: Hunter : Male awoken living in the jungles and hunting wildlife. He used to serve the Awoken leaders as a mercenary sent alone to finish treasure hunting and assassination missions with little to no success.Imagine his character being a mix of Star-Lord and Cayde-6 born and raised in a world similar to Avatar.He died in a treasure hunt but since he was never satisfied with his accomplishments, his soul could not rest and this could be the reason why the ghost found him and resurrected him to serve a greater purpose. Warlock : Male Human fascinated with science, magic and the manipulation of time.His character could be best described as the scientist version of Samuel Jackson. He was a special historian because with his inventions he could relive every planets history in seconds through a time-warp. With his time-manipulation techniques, he met the Vex and saw all their devious plans. In an attempt to change history and preserve humanity's future he fought the Vex in their dimension and lost (hence the different colored eye and face scar as wounds of the magic war). Scarred for life he was resurrected as protector of humanity by the Traveller and the ghost with only one goal, to wipe the Vex from the face of the Universe. Titan : Exo male , surprisingly enough he was a Sweeper Bot , a servant in the tower and a loyal follower of the faction leaders.He worked for many years without experiencing love or gratitude until the day that his production line would be discontinued and replaced due to its primitive AI. However, his AI was different and more advanced as it kept learning from human interactions.He managed to organize a small revolution that got shut down by the vanguards early on.He fled in order to survive and spent several years harnessing his powers.His raw strength and willpower to be as strong as his former overlords led him into the path of the titan. Many years later he returns to the Tower, accepted as a potent Titan while nobody knows his origin since he managed to upgrade every part of his skeleton over the years. His hatred and thirst for revenge remain, making him a villain who plots the destruction of the Traveller and the death of humanity. (He performs several subtle actions to kill guardians such as teasing them by throwing the ball off the tower, and kicking them in the face with Peregrine Greaves)
