Meltus may look like a scary dinosaur with fearsome looks, but he is actually a rather shy Mixel with a permanent sniffly cold and allergies to almost everything especially to fire and lava, which is ironic because he is an Infirnite. Whenever he and his fellow Infernite Cousins venture out to someplace new, he takes one sniff and starts sneezing flames. He often finds life hard with these allergies but despite them, he often does his best to get by.
