It's a good design, I just feel like there are enough characters with the color green already but it's fine, I like that he doesn't have legs like Rowen, it gives it a more deteriorated look and I love it
Did he destroy the toys and then bring them back or were they already destroyed to begin with? 
The tamaterros were designed like other designs for commerce after it was known that the first pal percy model was defective, but they were withdrawn very quickly from sale since apparently someone sabotaged the internal systems of those models, which is why most of them were destroyed. except the tama terros, they only became corrupted when Pal managed to control Percy's body
That's a bit of a long and complicated story (plus it's still a work in progress) but in the case of Nick's design...
NIDX first started as a kind of parasite that got inside a Percy mask, when Nick put it on, he ended up being controlled by this parasite and it used his body to continue traveling between dimensions. In the end things didn't turn out so well and it ended up losing that Nick's body, don't worry, the parasite like that Nick are fine.
If you are interested in his story you can look at my OC's project called "the second creators" on my Twitter ^^
I have a question I would like to ask. 1st Who is your favorite playtime with Percy character and 2nd can you draw your favorite playtime with Percy character in a plushie form along with the Percy poodle plushie?
welp- my fav character.... in general is lanki!, and if it's just the animatronics my fav is percy!!
what is this AU about? what’s the general plot and going-ons. :?
2. i’ve seen in your sketches/drawings that the gijinka-ified tama-terrorz + pal are kinda like toys/dolls, not just Tamagotchis. how do they function, and is there more to them? :0
3. Who is Leonardo? what is up with him…
if you don’t have much, then it’s alright! ^w^ i’m just very curious, like george… 0u0 (btw: LOVE THIS BLOG. your art/designs are so good…)
1- The main plot of the AU is to explain how the whole Pal-Percys and Percys Playhouse thing started but with the small change that the Tamagotchis are now more like robots
2.- They are basically like little robots programmed to be your best friends, they will play with you and try to keep you company while you take care of them!
3.-Leonard is the creator of Pal Percys and the Percys Playhouse characters! He doesn't present himself much to the public but he is a good person :]
What happens after the bossfight for Pal? I assume he wouldn’t get as easily let behind considering he has limbs
welp.... his legs fell apart at the end, only his arms were left. He tried to crawl out of the rubble to survive but unfortunately a truck ran over him when he tried to escape :[ so he canonically died in this AU
