Virizion shares a few traits with Suicune: They are both the same height, they both have a melodic in-game cry, they are both the last members of their trios, and both are the most feminine of those trios.
Virizion's shiny form seems to be the opposite color of the regular one, because they are switched around. The Body/Fur color is pink, and the accessory stripes are green. The other way around for the normal one.
The first part of this Pokémon's name is a reference to a glass, viridian. It's also a reference to the fact that Virizion is the more feminine of the threesome, as well as Virizion is a grass-type, and that the Pokémon's color; viridian, is a shade of green.
