That really depends on what moves your seviper knows. It also depends on what area you're going to go into. Seeing as how the seviper is poison, it's strong against grass pokemon, so if you're going into a grass type area, you'll be good. But, you'd have to find out what the seviper is weak against. You can find this out by checking the pokedex. Just type in national dex on Google and by whichever one you choose, you may be able to find out the Seviper's weaknesses and strengths. If it doesn't have very many weaknesses, then I'd say that it's a good thing to have on your team.
yes its a good team they sound tough together
You can only get Seviper in emerald
No. Siviper is in Sapphire/Emerald
Zangoose, the rival of Seviper, is in Emerald, Ruby, and Saphire. Zangoose is also in Mystery Dungeon Red Rescue Team and Blue Rescue Team.
You can catch Seviper in Ruby, Sapphire, Emerald, HeartGold (IV), SoulSilver (IV), Black and White.
In Sapphire and Emerald, you can find Seviper at Route 114. In Diamond, Pearl, and Platinum, Route 208(Sapphire has to be in the GBA slot.).
Seviper can be found in Route 114, which is south-west of Fallarbor Town. It is not accessible in Poke'mon Ruby, by the way.
You can't, you have to trade with Sapphire or Emerald. At least you get Zangoose! :D
what is your team?!?!?!
To get Seviper, you have to have Pokemon Sapphire or Emerald (Zangoose is in Ruby) and you get it on Route 114 near Lanette's house.
You must trade one over from Pokemon Sapphire or Emerald. It is spelled Seviper, by the way.
You can't get it in Ruby. It's only available in Sapphire and Emerald, where you can find one on Route 114.
