Maguro’s story in Puyo Puyo!! 20th Anniversary shows that Ecolo identifies as male. The existing translations don’t make it clear enough, so I’m retranslating the whole thing.
ECOLO: Hey you!
MAGURO: Gaaah?!★
RINGO: Just where did you seep out of?!
ECOLO: Stop having vaguely naughty conversations! And stop being so buddy-buddy with Puyo battles! It’s my role to subject Ringo-chan to shenanigans that go slightly over the line!
MAGURO: Yeah, no comprendo.★
RINGO: Wow, typical Ecolo. Shamelessly spewing phrases that most are too ashamed to say.
ECOLO: And even more, a pretty boy? Really? I don’t even know why you exist! I’m already more than enough for that character slot!
MAGURO: Uh, okay?★
ECOLO: You make me mad! Let’s!
MAGURO: Play Puyo?!★
