Oh I love Dragon Ball Z but my favorite character has to be Bardock.
Mugen char or Dbz char?
Mugen chars, all baltazar ones, he is godlike with his own style.
DBZ char, Trunks.
Beerus, just the movie one though. Super changed his personality a lot.
Vegetto and Gogeta are great too. They're powerful, and I like their fusion voices.
Well easily Vegeta as for second and third place
2nd ) Broly
3rd) Future Trunks
Well I am a fan of cooler. I thought the guy was a beast back when I saw his movies as a kid. I grew to like him even more after the TFS did their abridged version of the movie. Also is voice in both the originals and the abridged version were just magic to the ears.
My favorite character is Cell. He is enemy of Goku, but using Kamehameha~~! is so cool!! Japanese voice actor Mr. Wakamoto is good voice !＾－＾
Krillin, that guy has died too many times, he needs some love xD
In MUGEN, Goku Z2 by Balthazar
I like most of the characters, but the first is Vegeta.
I would have to say Vegeta just because he has that "Don't Give a Sh*t" attitude
- - - Updated - - -
because he is hard to kill in DBZ
vegeta because hes awesome.
plus hes the prince of all saiyans
Can't decide between Goku and Vegeta. Both of them are awesome.
Goku SSJ God
I was always a fan of trunks tbh
Mystic gohan,He reminds me of my childhood and Final bout (When i thought it was a good game...I was so wrong)
Tien. Because he's way more of a bald badass than Krillin.
I don't know if you were referring to a character that was ported to MUGEN and about their gameplay, but my favorite character from the series is Android 18. I felt like she really had a turn around from being a cold hearted robot.
If we're only talking DBZ, then it's Gohan (Both Cell saga Gohan, and buu saga Gohan)
My fav char was Gohan and Future!Trunks. I still believe that Gohan has been an awesome character (specially when he was a little child) with a nice growth. He was a nice protag on his arc but he kind of lost the protag when the angel Goku appeared. Future!Trunks was awesome, he was kinda fun but strong at the same time. One could say that he made Gohan a shadow, haha. I still love both of them.
