Iron Fist has a full-page street fight taking out a gang called the Golden Tigers. And yes, that’s almost certainly John Byrne as one of the rescued bystanders.
The gang is led by Chaka. A very strange name for a Chinese gang leader.
This is a short arc–Iron Fist takes Chaka down–but the villain will return one more time, years later, in Power Man and Iron Fist.
There’s a cameo by Peter Parker (wearing a Captain America shirt) and Mary Jane. I’m counting this as Peter doing cosplay for the purposes of tagging, just ’cause it’s fun.
