Sky and his father
As a child, Sky always looked up to his father, who was at one time an SPD Ranger. He acquired his father's powers from an accident in one of his father's experiments; as a result he was able to create force fields. When his father was in the hospital, he was given his father's battle damaged helmet, since that day Sky strived to be a Red Ranger just like his father. He joined SPD and as a member of B Squad, became the best at weapons and fighting along with his Dru, an alien. He was more serious minded and was neat and precise like a soldier.
He always was the first to be hard on Bridge's habits and ways of thinking, despite that Bridge was almost always right and he was almost always wrong. Despite that, the other Rangers though highly of him calling him "the best" Ranger. Even though he was in the top of his class, Sky made numerous mistakes early on such as when he mistakenly allowed the Troobians to confiscate a crate of diamonds and allowed Dru ( Who was now a villain) into the academy in an attempt to assassinate Cruger. However he was never usually punished severely and usually ended up doing chores.
When his A-Squad went missing, Commander Cruger had Tate and his B-Squad cadets bridge along with Sydney Drew stepped up and became the new SPD Rangers and protectors of Earth. Sky to his surprise was made the Blue Ranger-second in command due to his pride and Jack Landors, who was once a thief Sky caught was the Red Ranger and first in command of the new A Squad. Jack's friend Elizabeth Delgado completed the squad becoming the Yellow Ranger. Sky at first challenged Jack's leadership but eventually grew to accept him as the team's leader. After recapturing several monsters the team had caught in the past, Sky was assigned to interrogate Mirloc (who wanted Sky to reveal his most painful memory as payment) for the monster's identity. After capturing it, Sky returned to Mirloc and revealed his most painful memory, the murder of his father to Mirloc. Mirloc then revealed he was the murderer of Sky's father, Sky shed a tear allowing Mirloc to escape as it was a reflective substance (like a mirror).
Sky was angry at Cruger for not revealing information about his father's murder and sought out Mirloc. Mirloc then imprisoned The Rangers in a mirror until they were rescued by the Omega Ranger.
Sky was typically very serious and followed things to the book.
