Eelektross is one of those Pokemon that looks dangerous the moment you see it—and honestly, it is. It's a pure Electric-type with a weird mix of eel and monster energy, and because of its sucker-like mouth, it latches onto prey before shocking them with powerful fangs. In the Lumiose Pokedex, it sits at #144, standing 6'11" and weighing 177.5 lbs.
If you're aiming for a strong Electric-type that hits hard and has almost no weakness thanks to Levitate, Eelektross is a solid pick.

You can actually get Eelektross two ways: catching it directly or evolving it. Most players try both at some point.
Yes—Eelektross can be found in Wild Zone 20, but only after you finish Main Mission 38. Here's what you should expect:
A helpful trick:
Make a manual save before starting the fight.
If you fail to catch it, close the game, reload, and retry. Saves a lot of time (and Ultra Balls).
The easier and more reliable method is evolving your own line:
Thunder Stones are usually common enough that most players have a couple by mid-game, so this route is pretty beginner-friendly.
Eelektross' stats make it a flexible attacker:
It's not fast, but it hits hard both physically and specially. And since Levitate deletes its Ground weakness, it has great matchup value in many battles.
If you like Pokemon that can take a hit and punch back even harder, this one feels great to use.
If you're completing your Pokedex or building a shiny collection, yes—you can also buy a Shiny Eelektross Pokemon.
U4GM is a safe place to buy Shiny Pokemon Legends: Z-A, and the Shiny Eelektross is listed at $2.49.
Eelektross is one of those Pokemon that players forget about until they meet the Alpha version towering over them. Whether you evolve your own or hunt the rare Alpha spawn, it's a fun Electric-type that brings raw power and no weaknesses—always a nice combo.
