Rarijack also seemed pretty basic as a ship to me, just another variety of an 'opposites attract' ship that the writers for the show and the fandom loved. They just...argued. And learned things from each other. They didn't have that much of a connection? How were they challenging each other to grow and change out of their stereotypical roles? Their relationship grew, but the characters individually didn't.

Rarijack is pretty cute though. I liked them in the Equestria Girls special (Rollercoaster of Friendship) where it seemed like they actually wanted to hang out with each other, rather than in the show's early seasons, where it seemed like they were pushed together by outside forces.

Rainbow brought out sides of Applejack that we didn't really see that much, like her competitiveness. I like both the dynamics of Rarijack and Appledash, even though they were a bit simplistic, but I'd say that Appledash was better.

I'm assuming you chose this alien for Chase because it has super speed (like Chase in Mighty Pups). I also find it a little funny that Chase is the "hunting cat" instead of Wildcat (it's a hunting cat according to the Wiki, anyway).

Marshall : Cascan 

It deals with water. Makes sense for Marshall, even though it makes me think about what Zuma's going to be, lol (but I presume there's more than one water species of alien). It always bothered me a little in Mighty Pups that they gave Marshall fire powers when his job is to put out fires, but I understand why they did that (if Marshall got water powers, then I wouldn't know what Zuma's powers were going to be, either). 

Skye: Pturbosaurian

These look really cool, lol. I like seeing all the different species. Obviously you chose this alien for Skye because it flies, lol. 

Rubble: Talpaedan

Well, they even look like Rubble, lol. And they have the same abilities as Rubble, though they're way more powerful. It was a pretty obvious choice, lol. 

Rocky: Galvanic Mechamorph

They look really cool. And a species that's a mixture between plant and animal sounds right for Rocky. And they have technical possession, which sounds right for Rocky too. They can turn their hands into weapons or tools just reminded me of Rocky using tools as 'hands' a lot (like playing a guitar with tools, for example).

Zuma: Piscciss Volann

A fish species sounds pretty cool, and definitely fits Zuma. I find it interesting that they could be defeated by an evolved form of Everest, lol. 

Everest: Necrofriggian

They look really cool, and apparently they appeared in the reboot too (do you like the reboot? I've heard that it's bad, but I've never seen it). They lay eggs once every 80 years? I wonder how long they live for, and if all the eggs survive. Even sea turtles have to lay thousands of eggs every year, because so many of them are eaten by seagulls and the like. They can also form ice with their breath, which is Everest's Mighty Pups power, lol. They can fly, which reminds me of that one episode where Everest was in Air Pups. 

Tracker: Methanosian

A plant species makes sense for Tracker too. They can breath and generate fire? That's really cool. They can generate vine-like tentacles from their back, which reminded me of Tracker's cables. 

Rex: Kaosseffexx Ultimasauria

They look cool. And they're based off of dinosaurs, which obviously fits with Tracker. 

Wildcat: Kineceleran

Their feet have wheels on them and they appear to wear helmets. I know I keep saying this, but it's obvious that if fits with Wildcat, lol. They remind me of humanoid cheetahs, though they're way more powerful.

Liberty: Thep Khufan

They're mummy-like creatures. I'm not sure how that fits with Liberty, but it's interesting. They can slip through small spaces or tight openings. I'm presuming that that's why you picked this species for Liberty? She would be pretty hard to find a species for, especially since her job is crowd control (which Chase already covers, lol). 

Overall, it was interesting to learn about the different species. It reminded me of Skylanders (if you've heard of that) or Pokémon, even though the species were more diverse. I just read through the Ben Ten Wiki for each species, so I don't know how they interact with each other or anything like that (if they do at all). You obviously put a lot of work into this, especially with how many species there are. 

Thank you. But there are some mistakes I need to point out.

1. Panuncians are dupilcators. Not speedsters. 2. Mechamorphs are pure technology. Not planimals

3. The reboot is not bad.
