Evolved Arburian Pelarota

Evolved Arburian Pelarotas are metallic pillbug-like aliens from the planet Arburia and the evolved form of Arburian Pelarotas.

Biology
Evolved Arburian Pelarotas retain their normal counterparts' shape but have light blue skin and metallic pale blue plates with cylinder-like extensions that turn into spikes in sphere form.

Abilities
Evolved Arburian Pelarotas have powers similar to their normal counterparts but because their shells have spikes on them and their skin is metal-like, they have increased strength and durability, such as withstanding radiation and being immune to being trapped by sticky adhesives.

Evolved Arburian Pelarotas do not lose momentum in their sphere form, as their spikes give them additional traction.

Evolved Arburian Pelarotas can fire the spikes on their shells as projectiles.

Weaknesses
Evolved Arburian Pelarotas' metal shells makes them more top-heavy than normal Arburian Pelarotas, meaning that they are somewhat slower and more unbalanced when walking.

A Cerebrocrustacean's electrical force field can topple an evolved Arburian Pelarota.
