Alpha Wolf

The problem with this tactic, is you've neglected to remember that Frankie has been vastly updated whereas Mary wasn.'t. Titanium plating doesn't burn very well, as you find this out the hard way when you grab a nearby torch and shove it into Frankie's body. It doesn't do any notable damage. Frankie does some notable damage to you though.

He grabs your arm, breaking it in several places, and then takes the torch and sets YOU on fire, by shoving the flaming torch right through your body.

Fur seems to burn very well.
