And for more civs that could stomp the reapers:


 * Xeelee


 * Culture

 * Forerunners


 * UFP


 * Time Lords and Daleks.


 * Many, many, others. Honestly, the Reapers are a lower end SF civilizations. Atleast when comparared to:

1.6km ISD:860 TT per second.

8km Retribution class battle ship:5 PT per second.

1 km Forerunner warship:1.5 PT per second.

.8km Protoss supercarrier:40 TT per second.

Xeelee Handgun:27,000 YT per second.
