Character description from"tech spec": 
Landshark doesn't know where he got his name from, and he doesn't really care.  Some 'bots tend to confuse it with "Landmine," but once Landshark pulls his fist from their abdomen, they don't seem to get it wrong anymore.  Always the practical jokester and seen by his peers as a wise-guy, he often makes light of even the most dramatic situations.  Once, he had one of his power claws ripped off his body by a blood thirsty Narliphant.  Landshark didnt' fret about the situation; he simply turned to Flak and asked, "Can you give me a hand?"  ... Flak was not amused.  Able to transform his auxiliary battle platform into a hydraulic booster pack, he has the strength to wield two massive power claws capable of ripping open an emeny's armor plating.  This feature also gives him the ability to cling onto or climb almost any structure.  While in vehicle mode, Landshark enjoys intimidating, then plowing down, anyone that stands in his way.
