Aphelios is a return to what ADC's are supposed to be in my opinion. A ranged damage carry with little to no means of escape, spelling doom for the player if they are caught out of position.
He has a bunch of different auto attacks and effects that empower them, but that's all he is. An auto attack based champion.
If you observe his spotlight carefully in which he outplays enemies, you will notice he does it with a competent support offering their crowd control to create essential openings an adc needs to do their job.
You could easily call it the champion spotlight in which Braum carries Aphelios to be honest.
Also, he is shown to use flash to achieve multi kills. Without flash, he's stuck with walking everywhere.
I think he's the most balanced release by Riot in a while.
