Grim Junior's Father is a character who has yet to be revealed in Grim Tales From Down Below. There are a few possibilities about this topic.
Timmy is a possible character. Timmy has similar hair to Grim Jr, both have the same color and style of hair, and Grim Jr.'s left eye (when he is in soul form and manifesting his human face with his nergal powers) is also the same color of blue as Timmy's eyes. Timmy's godparents are Cosmo and Wanda while Grim Jr.'s godparents are Anti-Cosmo and Anti-Wanda. Fairly Odd Parents also already made an appearance in Grim Tales.
Drax is one of the predicted characters to be Grim Jr.'s father. In Grim Tales Afterbirth Drax has stated that he was in love with Mandy. So it could be possible that Drax had a short relationship with Mandy and made Junior together, this could also be why he had Grim Jr. aborted. It is also possible Grim hates Drax and does not like for anybody to mention his name.
Billy is also one of the most predicted characters to be his father. Billy and Mandy always had a good relationship during the series although Mandy stated she hates him she still hangs around with him. She also truly has feelings for Billy but didn't expressed that. However, Billy had died at a young age so it would be impossible to make a child with a spirit (unlike a ghost).
