Since there's no thread for the set... UNDERTOW -nice (armed) speed boat mode -blue connectors are fairly well hidden -clear cockpit is nice touch (could have been just painted or even unpainted) -rear panels to complete the boat mode are a nice touch, could have easily been overlooked without ruining the boat mode -satisfying transformation with enough steps to keep it interesting -robot mode is well articulated but the head is a bit difficult to turn because of the connectors on both sides sorta blocking the way -interesting headsculpt (reminds of something but I can't put my finger on it... anyone?) -arm cannons are badass -torso mode is very cool with the retro diver helmet and the shoulder cannons (also getting a King Joe vibe out of that headsculpt, dunno why, but I've always liked that ridiculously dated design) -no real knee poseability in that mode because you have to lock the legs straight... if you bend them at the knees, the lower legs kinda flop -colors aren't too in your face with the black, blue-ish grey, gold and clear green but they're nice enough (reminds me of HFTD Tomahawk or Cybertron Crosswise somehow) -another plus for me: Undertow is one of my favorite R.E.M. songs WATERLOG -very good robot mode -head turns! -interesting headsculpt (some kind of rounded helmet with goggles and breathing device) -weapon modes for boat mode and bot mode are almost identical but convincing compared to some of the previous PC Minicons -chest armor is identical to boat weapon mode but it works -too bad there's no jet mode with those wings!
