The earliest one I know of is Smoochum, at exactly Level 45. Of course, that's only from that event in Citrine Mountain with the Level 57 Beartic, and would take a lot of patience to grind up while keeping from evolution, unless you've got an Everstone on you.

 Ok thank you, I will keep that in mind.  I can be stubborn in my patience.

Hello everyone, it has been a long time since I lurked here. As the title says, what Pokémon can I get while under the lv 45 cap? I need some suggestions of them for a certain Garchomp.  I already know of the trick using a ghost type and curse but thought if possible, I would give perish song ago.
