It’s weird and slightly irksome how inconsistent all three fusion Legendaries are when it comes to Shiny colorscalyrex-ice and calyrex-shadow not taking the shininess of glastrier and spectrier into account. this is Very Little since these three mons are not even available shinies, but the idea annoys me lol
Calyrex - Calyrex itself is Shiny while the horses aren’t
Necrozma - Both the Necrozma prism parts and the Solgaleo / Lunala component are Shiny (their pinkish tone looks similar to their regular Shiny versions when in Radiant Sun / Full Moon phase)
Kyurem - The Kyurem parts are Shiny, while the Reshiram and Zekrom parts are sort of ambiguous (their Shiny versions are still primarily white and black, respectively, just with slight differences in hue), but here’s the weird part — Black Kyurem has Shiny Zekrom’s green electricity, but White Kyurem’s fire is red like regular Reshiram’s, instead of purple like Shiny Reshiram’s
I wish they’d just pick a lane
