At a glance, he resembles Shadow the Hedgehog, but with gold stripes and more unruly quills. Closer inspection might reveal his slightly misshapen right arm: the fur is much thinner and the skin beneath it is a dark maroon, and a few mechanical devices are set in it. This is his artificial arm, created with biotechnology. It allows him to focus his Chaos Energy enough to use it.


Whilst Umbra is an incredibly powerful Chaos user, his Chaos energy is unstable; while his base power exceeds most other Chaos users, he is unable to focus it to use more delicate techniques. His moves include:

His Chaos Energy is a sickly yellow tinged with neon green.

His artificial arm grants him even greater strength than he would normally have, which is still much more powerful than an average Mobian. He is incredibly fast and quite intelligent.


As mentioned before, despite Umbra's massive base Chaos power, he is unable to accurately focus it. This impedes his abilities to hit fast targets from a distance whilst maintaining an attack; he would have to get closer to the target and attack again. 

All of his attacks are very large; this causes him to rapidly burn through energy.

Whilst he is very intelligent, his intelligence is tainted with insanity, which can impair his judgement and cognitive skills.
