Why does Gengar have Levitate?

Question

I know it's a Ghost but In every game he is seen to be touching the floor.

Answer 1

There are some sprites that just don't make "sense", e.g. Celebi, Jirachi and Mew are all seen floating off the ground, but are not immune to ground type moves and nor do they have Levitate.

By the same token, if, e.g., Lunatone loses Levitate via Skill Swap or something similar, it's still seen floating even though it no longer is.

Comments

Thanks. I wish EQ could just obliterate that overused ghost.

It can be used when Gengar Mega-evolves; it gets Shadow Tag instead of Levitate.
Or something with Mold Breaker.

Answer 2

It can stand at will, but I saw some episodes where it skimmed the floor
