I, too, am a Time Lord-- admittedly a really weird half-Saiyan one, but still-- and I can support 11d's statement. We are always ourselves... We just show different facets of our personalities at different times in our lives. ;)
Oi! I am no son of Prince Vegeta the Irritable! I am a respectable elite hybrid, thank you very much. My father was a Saiyan, and my mother the daughter of Rassilon.
Well, my mum was a bit of a rebel... (She was also a total screaming genius, even by Time Lord standards-- she was even smarter than that Omega guy, who pretty much invented time travel.) She didn't exactly agree with me old Granddad on a lot of his decisions... She went off planet when she was only 110, and wandered around the universe until she ended up on a planet that was being scouted for purging by my dad, an elite named Zorn. She stood up to him, trapped him in stasis... And fell in love with him. (Love is dumb. And blind.) So, erm, eventually I was born... And when the Time War started heating up, my mum and I escaped to Karn. I learned martial arts from the Sisters, and my mum reverse-engineered my Zenkai boosts in conjunction with my regeneration energy... I ended up with a pretty decent power level, easily enough to protect the planet. (And yes, I did indeed punch a lot of bloody Daleks in the plungers.:). Didn't want to run, just had to fight. And here I am. :)
Cool it, mate.
