It will be quite a challenge, but you could teach it some Ice or Dragon-type moves. Stock up on Revives and Hyper Potions. For her Kingdra, you could use Twister, Dragon Rage, or Bite. I do not recommend sending Gyarados out to battle to face against one of her Dragonair though, because they know Thunderbolt, which can be a hefty move against Gyarados. Send out an Ice-type Pokemon, or a Pokemon that knows an Ice or Dragon type move for them.
ice. get gyrados from lake of rage and teach it an ice move, get suicune and level it up till it gets aurora beam or in ice path get a jynx or swinub, but be warned, if you do that you will likely have to spend a lot of time leveling up to the necessary levels. personally i would recommend suicune as it also comes in handy for beating the elite 4
In Pokémon Diamond, Gyarados will not evolve further.
Caterpie evolves into Metapod at level 7, and then into Butterfree at level 10
Level 36.
Bellsprout evolves into a Weepinbell at level 21 in Pokemon Crystal.
Three female Dragonair, all level 37, and a female Kingdra, level 40. Clair is her real name, by the way, and she specifies in Dragon types.

if your looking for a gyrados catch a magikarp and level it up at the day care till it can fight then level it up and it will evolve into a gyrados
Your magicarp will evole into a gyrados about Lv.20 or between levels 20-30.
there are two ways of getting a gyrados in Pokemon diamond: 1. you can use a super rod. 2.you can also use your old rod to catch a magikarp and then train it to level 20 or i think 22 so that it can evolve to a gyrados.
