So in the Giant Size Gwen Stacy which prints the 5 issue miniseries by Christos Gage and Todd Nauck that takes place in the Lee/Ditko era, Flash made a appearance as his team was playing against Gwen and Harry high school team. The Green goblin interrupts causing chaos only to attract the X-MEN, Marvel Girl, Beast and Iceman. Beast saved Flash and Flash acted like a ungrateful dbag calling Beast freak implying Flash may had been a anti-mutant bigot back in the day. Kinda makes sense, in Cullen Bunn Venom run did mentioned that Flash used to pick on a student who was gay using homophobic slurs which current day Flash felt really guilty about. He spoke to his past victim in current time and realized how much a impact his bullying and jerkish ways had. So yeah, expect high school Flash to be a Ahole since in college he started growing up and becoming a better person through Spidey influence.
