Though not much is known about Crysilon motivations or culture LEGO space forces have found them a tough and hard to contain threat. Often targeting small exploration craft they seem to 'assimilate' any crew they can capture.
The only thing everyone agrees upon is their total lack of colour co-ordination. This purple and yellow example seems to be a pick up craft for the recently converted.
I'm definitely a fan of the color explosion of a race known as Crysilon. It's nice to see something as different and original as this. Great build quality as expected from you: the engines are especially awesome.
