Wait a minute... the last time we saw Skull as a regular was only about 12 years ago. If Spike is his son, then is Samurai set in the future? If not, then Spike would've had to be born sometime during MMPR, and obviously Kim was never pregnant during that time.
Or maybe the writers didn't care and aged the character up to fit into the series, happens all the time.
kim had way better tast than to date that .
Except that during season 3 of MMPR there definitely was a connection between Skull and Kim, he was in love with her and she considered him a friend.
In Wild Force it was planned to reveal that Tommy & Kat and Skull & Kim got married and although the scene was never filmed, the idea caught on with the fans.
