Tynamo (Japanese: シビシラスShibishirasu) is an Electric Pokémon from Generation V.
Tynamo is a very small Pokémon with a white outside and a yellow inside. It has very small eyes and a small mouth. Tynamo's appearance is a bit like a triple cross-over of a tadpole, eel and a glassfish.
One can make Tynamo and its evolutions have weaknesses; by having the ability that ignores their ability such as Mold Breaker or Mummy, or moves that ignores their ability such as Simple Beam or moves that grounds them, such as Smack Down or Gravity.
Tynamos name comes from the words tyke and dynamo.
It has been pointed out that Tynamo's name backwards is Omanyte without the E at the end.
In Black and White, Tynamo is the only Pokémon that you can find in Chargestone Cave that N doesn't use in his battle against you there.
