Hello everybody! New to the forums, been lurking around for a bit now and since they're alot of threads about op classes but not much explaining atleast what i have found.
I wanted to know whats the most broken class/race you can be...and when i mean broken i mean ridiculously broken as hell. That could care less about the DM's choice or fights
Im playing in d&d 3.5.
(sorry foy english) and thanks for the help
If you're asking about OP combinations in D&D 3.5, you'd probably have more luck in the Previous Editions section. Particularly the Optimisation section.
Pun-Pun will likely be mentioned.
If you're actually asking about 5th ed, there has been a lot of talk about "broken" or "OP" classes, but little agreement about which ones those are. 
1) Wrong forum. 3.5 discussions go here.
2) Your request is bizarre, since I think you're confusing "class" and "character".
3) The biggest question I have is "why?"
If you're talking about The Most Powerful Character. EVER, in 3.5, that'd easily be Pun-Pun, whose list of abilities is truly staggering. He's so powerful that absolutely no DM would allow him, under any circumstances, since as soon as he appears all sorts of logical bizarreness occurs (and will have already occurred in the past, since time travel's on his list of abilities) - I hope you're ready to discuss cardinality and temporal paradoxes. He's what we call a "theoretical optimization exercise", created to see how far the rules can bend, rather than a "character", which would be intended to see play.
See if your DM will let you port the 4e Witchalok back to 3.5. It was released early in April 2009.
