This is a good explanation.

For one, The Monster Trio has made only one appearance in each of the shows, Blitzwolfer will appear in Moonlighting, according to recent sources, Snare-oh appeared in The Frogs Of War, as part of the Randomizer, and Frankenstrike will appear in Max's Monster to fight Phil as a Terroranchula/Human hybrid. Hopefully these will not be their only appearances in Omniverse.

On to Lodestar; I really don't hate or like him, but it will be good to see him again since the first episode.

Swampfire is not getting the attention he deserves because of the use of Heatblast and Wildvine; ironically, the two and their powers somewhat make Swampfire, and he is not used because of them already being unlocked in the DNA database for the Omnitrix.

Chromastone has less appearances because of Diamondhead and their similarities. I believe Diamondhead lost his ability to absorb and redirect energy because of Feedback, and the creators wanted them to have unique powers. Feedback is also the reason why Chromastone does not appear, because of their similar main power.

Jetray is a good alien, but Ben thought he was a solution to every speed problem he encountered in AF and UA, even when he had other speed aliens. That's why he was constantly used in the 2 shows. ChamAlien does not have a reason to not show up, besides his redesign. He should show up more as well. Fasttrack, in my opinion, was a plug-and-chug alien, as in he was just made out of the sense of laziness. XLR8 has the majority of his abilities, and can control and run at the speed he desires. So I really don't think it's necessary to bring him back, minus Fasttrack being stronger than XLR8.

Ripjaws is an original, and he also does not have his weakness of water any more, due to age. However, Ben has several other swimming aliens, notably AmpFibian, who can swim faster and has appeared in Omniverse at some points. Ripjaws should particularly be used for his swimming, extremely sharp teeth, and survivability in land.
