No, it cannot
You cannot get a Suicune level 40. Suicune cannot make eggs, and thus, he cannot be below level 40. No legendaries can be at a level lower than they are found at.
Suicune is not a possible starter Pokemon in emerald you must get a suicune from Pokemon firered or leafgreen.
After Suicune there is Regirock. You can find it at Sekra Range.
In Pokémon HeartGold, Suicune cannot breed because it is a Legendary Pokémon. Ditto can breed with most Pokémon to produce eggs, but since Suicune is not able to breed, you cannot obtain a Suicune egg through breeding. Therefore, Ditto and Suicune cannot breed together.
Suicune is a Water Type Pokemon.
Suicune is on Route 25.
Suicune does not evolve.
You cannot get a Suicune Egg in Pokémon SoulSilver. Suicune cannot breed.
In Pokémon Pearl, you cannot find a Suicune Egg anywhere. Suicune is a Legendary Pokémon and therefore with the exception of Manaphy is incapable of creating Pokémon Eggs with other Pokémon.
Umm i think there are three: entei, raikou, and suicune. but its probably just suicune
suicune is a rubbish Pokemon, if ya want it its not in emerald, its in Pokemon silver gold ruby and sapphire, ( they got rid of entei raikou and suicune to make way for rayquaza )
Use a Master ball on Suicune but there is an easier way get Suicune. Catch a Pokemon who has the ability of spell tag.
