(I wasn't sure whether to put this here or in Miscellaneous Mountain, but I went with here. So hopefully that's right.)
I myself discovered and gained an interest in Kirby via The Subspace Emissary in Super Smash Bros. Brawl. Despite how simple that seems, it's actually something of a long story.
Before that, all I remember is knowing Kirby's name and that he was a pink ball, probably because a Nintendo-obsessed friend I had in 2015 must have mentioned him at least once.
"Now then, hero of the Lower World...
You would risk your life for this land?
You would stand against me, the ruler of the
heavens? Very well... You will bow before the great
Queen Sectonia! My beauty rivals the divine...
And my power will crush all that you hold dear!"
"Bah... Aha... I see... I expected as much from the
hero chosen by the Dreamstalk. But I wonder...
how will you handle this? You see, true beauty...
is control. The Dreamstalk has guided you thus
far. But its bloom... will be your doom!"
