- "Overconfidence in our technologies has been our undoing. The entities learned from the very means that were employed to stop them. They have become a plague on our galaxy that is annihilating everything in its path."
- — Thor
This is Thor, Supreme Commander of the Asgard Fleet.
Likewise our efforts must be of a different type. We need to change from just ignoring those things which might harm us and actively prepare ourselves against the oncoming attacks.
In one particular episode there were three Replicator ships headed for an Asgard planet. The Asgard were in the middle of building a brand new Warship named the O'Neill. This particular ship was intended to be the first of its class and would be bigger and better than all other Asgard war vessels. Nevertheless, they would not be able to get the weapons system online before the Replicators showed up.
Samantha Carter had been brought to help come up with a plan to stop the Replicators from getting to the O'Neill and assimilating it into their technology. Her plan was referred to as a 'stupid idea'. However, the plan was to use the ship with higher technology to bait the other three ships into a hyperspace jump and then self destruct the O'Neill, thereby blowing up the other three ships as well.
Her idea worked, and the Asgard admitted that they never would have thought to Sacrifice the ship in order to eliminate the others.
