In Pikmin: Evolution Unleashed
The Diamondback Bulborb is a species of grub-dog appearing in Pikmin: Evolution Unleashed. It is the result of a Red Bulborb that has eaten an Evo Pikmin. Diamondback Bulborbs thrive in locations rich in metals, on which they feed, although they are content to survive in grassy locations. It has increased defense, much like the Hairy Bulborb, due to the purple and red jewels on its backside. A Diamondback Bulborb behaves identically to the Red Bulborb and eats Pikmin after chomping on them using its massive, sharp, red, jewel-encrusted teeth.

In Pikmin: Planetary Evolution
The Diamondback Bulborb, in Pikmin: Planetary Evolution, is an older grub-dog found only underground, where minerals in the soil help its crystals shine brighter. Its dwarf counterpart is the Dwarf Diamondback Bulborb, which it shares many physical characteristics with it, including the lethal crystals covering its backside.
