Ideas for Chaos Doubles

Ok I got the single (Anareeb) done, now it's time for the doubles. Also a rule for these doubles is that they must bear somewhat of a resemblance to the single of the non-Chaos element (so like Plasma/Chaos should bear some resemblance to Ghazt).

Here are the combos

1. Plasma/Chaos
2. Shadow/Chaos
3. Mech/Chaos
4. Crystal/Chaos
5. Poison/Chaos
6. (Maybe) Electricity/Chaos
