Um definitely NOT.

It never stated doing it alone

He could’ve done it with Neville and Luna

Tho if it means defeating Voldemort alone, no way. Harry would be dead in his fifth year

Yeah i agree. He definitely would NOT have been able to do it without Hermione

@GyaradosGyarados he would be dead in his 1st year doing it alone. Remember the chess set and the Devil's Snare and the potions in SS? He wouldn't have made it without Ron and Hermione.

Oh god I forgot about his first year for some reason

(don’t hate me, I posted that 10 minutes after I woke up lol)
