The Tenno League

Scattered across the Tenno Region are the eight gyms of the Tenno League. Each one is lead by a Gym Leader of exceptional skill. Once all eight badges are obtained, a trainer gains access to the Pokémon League of the Tenno Region, where they face the Elite Four, and then finally the Champion of the Tenno League.

As Ash faces the Gym Leaders of Tenno, this page will updated with each leader’s descriptions.

    • The site’s still under construction for the most part. Also it parallels the story I’m writing, so this page only includes the ones shown there to avoid spoilers.


  1. I’m just going say this now before writing the rest but, I understand all of you’re ideas for this and I respect that, here are just some helpful inputs.

    I was looking at the 3 gym leaders and champion (as of now) and I’m going to say my reaction was a mixture of understanding but also.. disappointment, let me explain. Of all 4 league members, they all have something to do with space, which with the astronomical region, I somewhat believe. I feel as though that gym leaders and regions are based off of real life, where everyone does something different – which can be reflected in the leagues, besides RBY (which they tried to flesh out the gym leaders in the manga and anime) I can’t think of a region where 2 gym leaders have the same branch of work. Besides Cilan,Chilli and Cress but they doesn’t count since they’re triplets, it makes sense. I understand what you’re doing with the whole different parts of astronomy and they all work together, but it over time just kind of doesn’t flesh the character out as unique, it just makes them feel the same to everyone else.

    Please don’t take this as hate (because I know a couple of people who would get offended by my pickiness) because I love all you’ve done with this region, but when it comes to this it seems somewhat bland.
    Good Luck.


    • Thank you for your thoughts. Do not worry, I totally understand where you’re coming from, and I appreciate the constructive criticism. I also see what you are saying and you make a good point. Back when I first envisioned the Tenno Region and my Luna, Terra, and Sol Versions I had what I thought was an opportunity to be unique and create an entire region with a running theme to it, something that has yet to be done to any large extent in the actual games. I would hope that each leader having their own category within the broad field of space-based and physics research would be enough for variety, but I can see where your concerns come in as well. I look at it as we have a meteorite hunter, an orbital skydiver, a nuclear physicist, and an amateur stargazer. Yes, they do fall under the general theme of space, but each is a completely unique profession in their own right as well. Though, I do admit that this could be my bias as a complete astrophysics-nerd talking here.

      As my ability to flesh out the leaders on this page is fairly limited, I can’t do too much to help what you see here, but I will strive to better flesh out each gym leader in my story, and do my best to infer their more in-depth characters from the game concepts. However, I do want to stick to my original idea of having an overarching theme, because I really do think it’s an idea with so much potential. Maybe I’m not going about it right, but as of right now I’m not sure how else I could accomplish it.

      Once again, thank you for your thoughts, and I apologize for the disappointment.


  2. Hey. Is there’s a Pokemon trial captains after seeing the gym leaders right here in the Tenno region with badges for the Pokemon league?


  3. Okay. I guess not. How many badges until Ash will have to collect them first before he can battle with Neil on Pokemon Cosmic Quest?


  4. To be honest with you, I think having many Gym Leaders and Elite Four Members (and the champion!) be aligned with some kind of cosmic occurrence, or have a job involving space is a really nice touch. I mean, somehow connecting Ground-types to space is amazing. However sometimes it seems a bit bland but I don’t care. There aren’t many space theme gyms (that I remember at this time) so I think it’s a nice touch for a region like this. By the way read your fairy fan-fiction it’s really cool (Fairy and Dragon are some of my favorite types).


  5. I couldn’t help but notice that your two Elite Four members are of two of the four starter types. I hope this means that the other two are going to be Grass and Electric type specialists. That would be cool. You’d not only have a perfect quartet of people representing the most basic part of Pokemon, but Grass and Electric have never had Elite Four members based on them. Really, I hope you do introduce us to the other two before your story’s up.


    • I won’t confirm or deny that the other two Elite Four members will be Grass and Electric, but I will say that it is my goal to have all four of them appear in Cosmic Quest at some point, seeing as Cosmic Quest is the only way I really have to show them to the world.
