Also, they're pocket monsters because they're small. And reduce size to get into pokéballs (that was canon since the 90's and re-confirmed in PLA)
Pokémon can't overpass a ton. Or 10 meters unless they're with a special form or are serpent-like.
The biggest was Wailord 14 meters, compared to real blue whales over 40 meters.
The entity supposed to MOVE CONTINENTS is not even 4 meters tall.
Eternatus being called the "giant pokémon" 20 meters long. And I don't count Eternamax since Dyna/Gigantamax are mostly illusions.
