i know that people saying taehyun is Kirby because he can open his mouth really big but this is my take:

yeonjun: kirby because of their squishy cheeks and hes the biggest foodie, very affectionate but also very strong
taehyun: waddle dee, literally just eyes and squish, also could be bandanna dee because of his fierce loyalty
kai: elfilin, kind and caring, always trying his best to help and is willing to sacrifice himself for the greater good
beomgyu: marx, looks very cute and innocent but has a chaotic side to him, kinda matches beomgyu when he plays mind games in to do
soobin: meta knight, some people think hes very stoic and serious, but hes a great leader and cares a lot about his crew and makes sure they dont get hurt

this start off as something unserious but then it got serious 😭
