Appearance - Harry has slightly spiked, blonde hair and a red glow to his whole body. He's not very tall standing at 5'7" and has a skinny figure. He wears a pair of jeans and a leather jacket which he has found that he is incapable of taking off in his new ghostly form.
BRIEF Bio - Harry doesn’t remember many specifics about his time in the land of the living but he does remember living with his somewhat distant parents all the way up to his demise, whatever that may have been. Harry’s memories as spirit have been much more vivid however. Harry was stolen away from the true afterlife by a necromancer who sought to summon an army of thousands of mundane souls to help him take over Las Vegas and later on the world. At this point Harry was little more than a slave to the will of the necromancer but this was quickly cut short as the young Zatanna put a stop to the evil magic user's plans along with John Constantine. 

After defeating the necromancer all of his summoned spirits were set free once again; all except Harry that is. For one reason or another Harry remained but now had his free will back once more. Harry was pretty frightened at first but Zatanna managed to calm him down enough for him to begin to come to terms with his situation. Harry hung around Zatanna for awhile longer as she and Constantine seemed to be the only ones capable of seeing or hearing him due to their own magical nature. The spirited teen would follow one or both of them around for a month whilst helping them on some of their heroic excursions until Zatanna offered Harry a spot on a new division of the Justice League... Young Justice.
Notes - 
-Harry has some skill in hand-to-hand combat and swordsmanship though both of these are very minor and have loads of room for improvement.
-He misses the sweet release of sitting down.
[hider=Sample Post]Sample Post: make sure your tense matches up most of the time. I made the first sentence two sentences because you went from 'was a calm night' to "area is at" and went from past tense to present tense too quickly. 

It was a calm night in Blüdhaven. The overall crime in the area was at a record low. The faint sound of late night drivers and riders accented the cold air and added to the beautifully chaotic ambience that was Blüdhaven. This tranquil symphony of urban sounds was pieced quickly by a ear curdling scream.

Mike ran down the alleyway as he was chased by a finely dressed white-clad man on a pure white horse. 

"Please, leave me alone!" Mike called in between heavy breathes as the white clad Gentleman began to get closer and closer. 

The one advantage Mike had on the fiend was all the twists and turns in the alleyway but that luck ran out as the alley ended with a packed parking lot with not a single living soul in sight. Mike looked frantically around for somewhere new to duck into but in his search he failed to watch where he was stepping and tripped over a median. 

"Now thou'll feel the cold touch of thy's ghostly steel!" The apparent ghost called out as he drew a rapier from his side and leaped from his steed at Mike. Mike prepared for the worst but was instead greeted by a loud 'thwack' noise which was followed up by the sight of his assailant strewn out in front of him, rubbing his jaw. 

Mike prepared to get up and run again but he quickly lost consciousness  before getting the chance to get away...

...and now Harry was in control. 

"You know you could have had a pretty good career as a stage actor Haddock." Harry said as he walked over to the villian's discarded rapier while he was stunned "but you just had to go to a life of crime"

Harry in Mike's body slipped his foot under the sword hilt and kicked it up, grabbing it and pointing it at the now recovered Haddock.

"Who are you?" Haddock said as he stumbled backwards in a vain attempt to escape.

"Harry. But you can call me Giest." and with that Giest leapt into action.
