Looking at this point of view, we can list almost all Evolved species as "useless". Evolved To'kustar, Evolved Polar Manzardill, Evolved Galilean, Evolved Arachnichimp and Evolved Vulpimancer (respectly, Ultimates Way Big, Arcticguana, Gravattack, Spidermonkey and Wildmutt). All of them don't have a markedly different power, just upgrades of the original ones.

Evolved Arburian Pelarota can perform a ranged attack, firing its spikes as projectiles. However, Ben and Albedo never showed this on the series.
