anythig with a decent fighting move like close combat
Go to Snowpoint city and on your way there are sneasels. Just have your sneasel evolve to a weavile.
go to snowpoint city and look in the nearest grass. there are sneasels all over the place
Your rival gets whichever Pokemon type yours is weakest to. ie you take the water, rival takes the grass.
Your rival will have Chikorita if you pick Totodile as your starter pokemon.
You must give it the item Razor Claw and level it up at night time. You can get one in the Pokéathalon dome or sometimes wild sneasels will be holding one. I advise battling wild sneasels and using the move theif to get any held items.
You actually get to name your rival. So, your rival is whoever you want him to be. The rival is just a strange character that happens to be eying Professor Elm's Pokemon.
The champion is your rival.
Your rival is the red head named ???
You get it from wild sneasels.
your rival would pick a water type Pokemon which is a squirtle
you can name your rival's name whatever you want.
your rival is a boy name him whatever you want
