So, as we all know, Transformers are often referred to as "robots in disguise". But is disguise the only thing their alt mode is good for, or do their alt modes give them abilities that they are incapable of performing in robot mode? For instance, are TFs able to move faster in vehicle mode than in robot mode? I personally think it's incredibly obvious that TFs use their vehicle modes to increase their movement speed (if they are a car), increase their fire power (if they are a weapon or tank), increase their flight abilities (if they are a jet or plane), etc. But others apparently disagree with this notion, so I thought I would open it up to discussion. What do you guys all think?
