This is my take on Gigantamax Plusle and Minun. I based them off of Phineas and Ferb, the title characters of Phineas and Ferb.
Shiny Plusle has reddish-orange markings, which will allow for more orangey stripes on Shiny Gigantamax Plusle's shirt while still keeping the reddish vibe of the ears; and Shiny Minun's green markings will mean that Shiny Gigantamax Minun will look even more like everyone's favorite Britizen of action.
