Who's taken over Shredder's lair? Karai. Who is in control of all the Foot Ninjas now? Karai. Who wears Kuro Kabuto now? You know, the helmet that Shredder said only the leader of the Foot Clan can wear. Hm, let me think for a sec. Um, KARAI!

The mutants you just mentioned are just henchmen who are loyal to Shredder now. Karai has full control now of the Foot Clan organization. If there is a resisting force, it is now Shredder's forces, as Karai has the Foot at her fingertips (no pun intended).
