A few questions about DC adventures rules

A few questions about dc adventures rules
1, How would you replicate knockback from a super-powered punch? Is it Added Effect?
2, How can you get enemies to attack you (aggro)?
3, The Added Effect part of critical hits seams quite weak, am I missing something?
Thanks
