I'm sure yes. I realized that there are always new things here, on this forum, so I will always have new opportunities for further exploration.
And well, my favorite Pokémon of the three types I mentioned?
I will mention them one by one.
Among the Pokémon introduced in Kanto, Venusaur, Beedrill and Nidoking were the Poison types that I used most.
I've used Venusaur many times, it's one of my favorite Grass-type starters, and it's helped me in a lot of risky situations. Against most gym leaders in the Kanto region, my Venusaur were powerful, often going undefeated.
Beedrill is one of my favorites here, mainly because I really like its design, and its offensive power stood out, in my eyes. I think Weedle is cute, besides. One of my first shinies was a Shiny Weedle, which I found by chance, when I was training my team. I threw a PokéBall as soon as I saw it, and it went in, without any fanfare.
When I used it, Nidoking was the one that proved to be the most powerful in attacking. My Nidoking were victory machines, they defeated everything and everyone who foolishly decided to get in their way. When I entered the field, my Nidoking's victory was guaranteed.
Now, of the electric types, the one I used most was Pikachu. He's one of my favorite Electric types, powerful, fast and everything. Watching the anime also made me like Pikachu even more. Therefore, whenever possible, I have a Pikachu on the team. But I don't hesitate to evolve it as soon as I get a Thunder Stone, Raichu needs more love.
Ampharos is next, and I don't need to tell you why I like Ampharos. Powerful, but not that fast. Cute, but with destructive power.
From the second generation, Ampharos is one of my favorites, without a shadow of a doubt.
I wanted to talk more about Electric types, but I need to talk about my favorite Fairy types. This message is longer than I would have expected it to be.
Togekiss, Florges and Gardevoir are at the top, without a doubt. I started liking Togepi and Togetic since the second generation, and when it got a new evolution, I was ecstatic. When the fairy type emerged to shake the throne of the undefeated dragons, I knew I had to have a fairy type on my team.
Gardevoir is a Pokémon that I really like, it is a fast and powerful Pokémon, which surpasses the speed of all the opponents I have faced when using its abilities. However, I'm sad that this is yet another Pokémon that people and the internet destroyed.
Florges is everything I could want in a Pokémon. I like flowers, and I think Flabébé is a very curious Pokémon. Like the other two mentioned above, Florges is one of my favorite fairy types.
Well, I guess that's it...
