Ok so I'm currently playing through GTA V for the second time and came across Wade again. Wade has some great one liners in the game and makes me laugh every time so it got me to think, what is my favourite character from each GTA III onwards that weren't the protagonist. As most people usually place protagonist towards the top of their favourite lists which is understandable as we do spend all of our time with them while in the game.
For me I would say:
GTA III - Ray Machowski - He was the emobdiment of what I think to be pissed off old detectives. Plus he spent alot of times in male bathrooms
GTA VC - Ken Rosenberg - Lets be honest we all know how much Ken was a huge help to Tommy.
GTA SA - Frank Tenpenny - Probably my favourite antagonist in all the GTA games, plus Samuel L Jackson did amazing with the voice acting.
GTA Advance - (Never played)
GTA LCS - Donald Love - I chose this one as he really is the best out of a bad bunch in my opinion. Plus he did eat Avery Carrington.
GTA VCS - Phil Collins - Self explanitory, its f*cking Phil Collins.
GTA IV - Roman Bellic - How could you not love the little fat bowling f*ck.
GTA TLaD - Jim Fitzgerlad - Very loyal to Johnny K and seemed very cool, I personally would of preferred if he was the protag over Johnny.
GTA TBoGT - Yusuf Amir - He gave us a gold car.
GTA Chinatown Wars - (Never played)
GTA V - Wade Hebert - Probably my favourite non protag of all time. His voice really makes this character
