XLR-Mutt is a fusion between XLR8 and Wildmutt, and forms part of the Biomnitrix Unleashed project, as well as being one of the original fusions from the DNA Lab. This remake was created by Rizegreymon22 of Deviantart.
XLR-Mutt has Wildmutt's physical form with XLR8's colouration, and XLR8's helmet with Wildmutt's lower jaw protruding from it. Wildmutt's nostrils are present on the neck, and his forearms end in three claws similar to the claws on XLR8's hands. His rear legs are those of XLR8, as is his tail, and the spines on his elbows. His chest is green and the Biomnitrix symbol is located in the centre of the chest.
