Audition tapes for next superhero to debut on The Flash

Some audition tapes have gone online for the next superhero to debut on The Flash season 2!

"the new superhero, who is named as "John Clark" in the audition tapes. (Keep in mind this is probably not his real name and just the producers trying to keep us nosey fans in the dark for a little longer). The character is an older man in his 30's to 40's, and even refers to Barry as "kid" in the audition tapes. He knows Barry's secret identity and has a rocky alliance with team Flash. The character also has trouble controling his powers and envy's Barry's ability to do so. This character is said to be one of the main characters for the season and will appear in multiple episodes."

Some other info from the auditions:

-The character got his powers from the particle accelerator
-The character's physical body was affected by the incident
-His powers are considered dangerous if uncontrolled



I was hoping that we would see Hal Jordan this season, but from some of the details in the audition scripts it doesn't sound like this is him.

Would love to see Elongated Man as well but this also doesn't seem to describe him either.

Any guesses on who the character is?
