What team can beat KRU relic 4?

Anyone with healing immunity or shock

Any character who can inflict healing immunity would work, like IG-88, GG, and others. Malak would be inefficient but could eventually gain the ability to use healing immunity. Or use nihilus or mando; I once had a GAC team of 4 leftover tanks and my weak nihilus to beat a solo KRU

If you stick GMA on your JKR team should be able to do the trick
