The fact that I'm still in shock even though everyone should've seen this day coming because it's the title of the show. What a pitch perfect portrayal of death and immediate grief. The lack of closure, the banality, the way the world stops and keeps moving on at the same time.
This show is about to be so insane without Logan because he consumed so much space and drove the motivations of basically every character in one way or another. Now we get to see how they move when they're all "free".
The trend started with The Livestrong Campaign in May in 2004 by Lance Armstrong. The campaign sold yellow silicon gel wristband bracelet that read Livestrong and launched as a fund-raising item to provide support for people affected by Cancer. It became so popular, shortly after you could find them sold just about everywhere for every occasion and in about every color after.
Fanart I did of Marc Brown's Arthur, the whole cast (not everybody on the show ever because that would need waaay more pages lol) calling out my boi Arthur
Love the art. Can't wait to see your version of the Plumbers' Kids (and Kevin's transformation), but it got me thinking. I know you retconned the Rooter retcon, in that they're not genetically modified hybrids, but how did they come to be?
It's hard to imagine an osmosian and a human creating an offspring considering they're completely different species, let alone a tetramand or a pyronite.
I have a whole system behind hybrids in Ben 10. For starters, quite a few aliens can have kids with each other naturally if they are close enough. So a tetramand and human, or even a kineceleran and human, can have kids, they just often have to be wary of issues that could arise.
But the more unnatural a pairing is, the harder to have a kid is naturally, to the point that you get cases where they can't have a kid naturally. But there are many facilities that help via science to help parents have kids if they can't naturally. This is often taking the parents gamete cells, and raising the baby in a test tube like environment so they can control the entire process from the start, sometimes having to select specific genes to make sure the kid can live a healthy life.
One of the most successful facilities is on Galvan Prime, run by a galvan doctor named Doctor Geno, she's a friend of Azmuth's sister.
Of course there are limits to what aliens can have kids with each other, but as science grows each day, some things that were thought to be impossible have become possible, so you never know what could be made next.
Hybrids also seem to function a 70/30 percent rule, in that they take after one species gene more than the other. E.g Helen is more kineceleran than human. Hybrids can only be two things as well, you can't get a big mix of many aliens in one alien. Though there are some that break these rules, like anodites and osmosians due to how their genetics work.
So in terms of the plumber kids, ones like Helen and Manny were naturally made, though Alan was made via the science route when his parents went to one of these facilities.
In terms of Kevin, since you mentioned osmosians, they behave more by inheriting powers. Due to osmosian having DNA absorption, it means a lot of them are able to have kids with many races, but their hybrids don't look like them. They will always look like the alien species their other parent is, beyond maybe getting minor things like eye or hair colour.
What the kids inherit is the matter and energy absorption powers, though not really the DNA absorption (unless the omnitrix is involved lol). So they're kind of a changeling vibe with them. So Kevin looks entirely human, but as a hybrid as the powers.
