Koon, Sarr Labooda was going to be his name, but at the last minute they changed it. Check the Official Site databanks and you'll find Coleman Trebor right there.
Julie, Trebor is named after Robert Coleman. He was part of the CGI stuff for Episode II, and he had (involuntarily) Trebor named after him.
Look, Jedi are damn hard, able to take on many times their number. CT was a COUNCIL member. If Jango had actually made some EFFORT (like, say, blasting under Trebor's guard with his jetpack and firing upwards) I would have thought @Blimey, he went down easy for a Council Member!"
As it was, all Jango did was stand there and shoot, something any normal Jedi seems to be able to repel more or less indefinitely. It was beyond terrible.
Jango's death was stupid. He had so many weapons he could've used and he just used his blaster. C'mon! Even Boba put a better fight in ROTJ against Luke. I know Mace is suppossed to be tough, but Jango fought like a moron. Jumping for the lightsaber. What was that all about?! That made Jango look like a bumbling clown. He just should've fired at Mace. As for Trebor's death . . . that stupid as well. Jango killed him way too easily. Trebor sucked for a Jedi Council Master. Did you notice that Dooku was reaching for his lightsaber, when Jango acted first. If Jango hadn't been there, it would've been interesting to see if Dooku could've drew his lightsaber in time to block Trebor's attack.
