Poppy is the paragon of Demacia right? Why doesn't any of her shouts scream DEMACIA like the rest of the Demacian characters? Jarvan does it, Garen does it, Xin does it(?), and Lux does it? Why not Poppy?

Commando skin perhaps?

I'm surprised they didn't give her a "Bling" skin.
Stunna shades and big ol' clock for the neckbone. She's Poppy right? Poppin' and stunnin' and stuntin' and rollin'
get that, hit that, quit that. ya HURD me!

eh?
I'm full of bad ideas.

Xin Zhao and Galio do not as well. The only reason I can think of is that all three of them are technically not native Demacians...though Galio being constucted makes that confusing.

She resides in Demacia, She's not "from Demacia"

Poppy is not a native Demacian. She's the Yordle ambassador to Demacia, if I remember correctly.
