Hard to choose just one...and these may be incomplete...
Fox Mulder (The X-Files)
Twisting Tiger (Supa Strikas)
Mabel Pines (Gravity Falls)
Gordon Freeman (Half-Life Series)
GLaDOS (Portal Series)
Kenji/Zymeth/Koril/Issyl (Battle Realms Series)
L (Death Note) Near comes a close second.
Tamaki Suoh (Ouran High School Host Club)
Kyu/Ryu (Detective Academy Q)
Other notes:
I probably can relate the most to Walter White from Breaking Bad, but he's not a favorite.
