A Mummy Cow from the obscure Saban's Monster Farm, it's easier to search like this because Monster Rancher came out at the same decade.

She's a pun on Cleopatra and is a Cow Cowapatra dig it?

Most of the fanart was draw by LonBlueWolf, a prolific "Furry" artist, give him some love, he's always drawing obscure characther's, the rest is small collages from the original series, one of the voice actors uploaded a full episode, some of then you can find in Russian or Spanish but no DVD/Blu-Ray release was released i guess.
