Doldog

Doldog is a female alien whose face looks like a bulldog.

Appearance
She is an anthropomorphic dog whose face looks like a bulldog and light-brown hair in enormously large figure.

Plot
In the chapter 105 of To LOVE-Ru (adapted in the Episode 4 of Motto To LOVE-Ru), she fell in love with Maron and went after Haruna as she is taking out Maron for a walk.

Thanks to which Doldog covered the face with a mask, Haruna mistook her as a stalker and talked to Oshizu, Lala and Rito. They set a trap using the Maru-Maru Change-Kun to swap Haruna and Lala bodies and the latter went to take Maron on a walk. And Doldog appeared, Oshizu used her psychokinesis to defeat Doldog. When the alien confessed her true intentions and revealed true face, Oshizu (who is very afraid of dogs) beat her even more and Doldog ended up fully injuried in Mikado's Clinic.
