The thing with Sabretooth and Wild Child is that they're two, two, two models in one! That's right. While they start the game connected at the base, you can send Wild Child "off the leash" and have him run around and attack other things as he pleases. He can then be brought back and reattached if you so desire. Considering the healing factor on these guys, you're always going to have to make sure to deal extra damage to them, as there's a chance they can just heal it all back up again if you try and nickel-and-dime them to death. No, if you're going to KO this pair, you'll want to do it as quickly as possible.
