It's at lvl 50.
Lots of ultra balls to catch it, a Pokemon around level 50, Pokemon that know surf and strength.
in both firered &leafgreen articuno is of 50lv
You can't catch mew on leafgreen you need gameshark codes for that
Yes,its level is 70.
I used a Level 59 Articuno. It must know Ice Beam and Blizzard
1. Mewtwo, if you catch him in the Cerulean Cave, he will be at Level 70!!!
50
Yes it is actually a very good team get them to a high level and youll pwn
Catch Hoppip in the Five Isle Meadow or Memorial Pillar (Mostly) and get it to level 18.
No Pokemons evolve into Articuno since its a legendary pokemon. NO ONE!!!!!!!!!!!!!!!!!! ARTICUNO IS A LEGENDARY POKEMON DUMMBUT
You need to catch Marrill first. Its on four island in the water near the Pokemon center. I think you catch it by fishing or surfing. Then you train it. When its at the right level, it will envolve into Azumarill.
Terribly sorry but you cannot catch a URSARANG in Pokemon LeafGreen but if you get a friend who has the game Pokemon Emerald, tell your friend to go to the Safari Zone and catch a TEDDIURSA and level it up until its a Ursarang (I think it levels up when you just raise it by 1 level because most of the Pokemon in the Safari Zone level up in their next level). **note: Teddiursa evolves into Ursaring when it reaches level 30 (or above).
