Although the transformation did make them larger and stronger, they remained bungling, incompetent simpletons and were completely inept at stopping the Turtles or carrying out Shredder's plans. Throughout most of the series, they tried to attack the Turtles with brute force, without applying knowledge and strategy. In the episode "The Missing Map," when the two were accidentally caught in Krang's "brain extraction" machine, the results concluded there was "no data to extract," implying that the two possessed little or no knowledge. Most of the time, the Turtles consider them to be formidable in combat (despite their stupidity) due to their great strength and endurance, and as such, often use their intelligence to outwit them rather than fighting them in a straightforward manner. But their attempts at the turtles seem to regularly fail due to their incompetence and goofing behavior, which all leads to them being abused both physically and verbally by Shredder and Krang, and the former even fired them in one episode.
