It needs a TM it can't learn it by leveling up I don't know what TM or where unfortunately sorry
I know Charizard can.

There is no such move as "Blood Razor," unless it's an attack in a fan-made hack I'm not aware of. Therefore, Charizard can't learn the attack.

The Pokémon that can learn Fly in Yellow are Charizard, Pidgey, Pidgeotto, Pidgeot, Spearow, Fearow, Farfetch'd, Doduo, Dodrio, Aerodactyl, Articuno, Zapdos, Moltres, and, if you use a glitch or cheat to obtain it, Mew. However, it should be noted that none of them learn Fly naturally; you need to use HM02 to teach it to them. Also, as a side note, Charizard is only capable of learning Fly in Yellow, not Red and Blue.
