I do have a few more ideas for dreams if chainsaw wants to continue this kind of event for some of the Mythic legends. Mew dream would have her getting inflated and stretched so big she would be the size of a pink moon in the sky and can say "that's no moon, that's a Mewn".
For Deoxys she can dream she is on a talk show but speaks regular language but she is a scientist and explains scientific equation for space travel that no one understands like "by using clefary string theory in conjecture to the requaza anti gravity loophole minus palkias spatial equation, teleportation through the cosmos is likely to happen, now don't get me started with the psyduck inverse algorithm included, now that is a real headache" she can be understood and not understood at same time.
Darkrai would be different where her dream is like a Childs cartoon where everything is bright, happy and nothing can go wrong everyone hugging, with the sun having a smiling face. Darkrai would be a cute little fairy and she would absolutely HATE everything about this no dark corner to hide in, cant hurt anything even if she tried or herself. She would be in a fetal position. This would be her ABSOLUTE WORST NIGHTMARE.
Maybe Melmetal could be like the liquid terminator from the movie always able to change its shape so can change size of breasts.
I did notice a typo in the registeel end section where at the bottom in blue where its supposed to say "Registeel CAUGHT!" it says "Regice CAUGHT" in blue. It still works just the wrong name is there.
I had an idea for Genesect where she would be in a hidden team plasma base or an abandoned one and the MC would find it using legendary pussy sense he developed after going for so many legends. The original researcher who created the program to make her wanted to create his perfect girfreind/ lover but had to work with plasma to get the funds. He left in the machine a horniness code that if stimulated would get her to imprint that he was her lover/master but something happened and was left in a hidden section of the base that even plasma did not know about. If the base is still operational then this can be a infiltration mission to get her out where plasma will send her away if an alarm is raised to keep the one chance rule of mythic.
An idea for Volcanion can be the fight against her is not to tire her out but make her run out of her stored water. Once she runs out she heats up a lot and will look for the closest water or liquid nearby which is when the MC goes in to refill her. Afterword's she can learn a new move called "CUM CANNON" and could paint a town white if she was not so attached to the new liquid and its source.
