Abilities are something that cannot be different from what a species normally has.
E.g. Charizard's abilities can be either Blaze or Solar Power, and those are the only two abilities it can have (excluding hacking to give it a different ability). It doesn't matter if you breed with it with a Pokemon with Levitate, its ability will be Blaze (since Solar Power is an unreleased ability).
Also, you don't need a Charizard with levitate since it's already part flying type, meaning it's immune to ground/ entry hazards other than Stealth Rock.
