2nd appearance of Sabretooth.
Constrictor appearance.

"Misty Knight and Colleen Wing have been hired to steal back the Jade Tiger, which has been stolen by a group of thieves led by Sabretooth and Constrictor. When the girls are confronted by the two super-beings, Misty's cyborg arm is caught in the vault's magnetic lock and sealed inside while Colleen is seriously wounded by Sabretooth, but manages to escape.

As Power Man reconciles with Harmony Young, Iron Fist is busy training with Bob Diamond. The latter two are interrupted when the wounded Colleen bursts in and tells them what happened. Danny goes along with Power Man to rescue Misty from the vault. This brings them into conflict with Constrictor and Sabretooth."
