I love Professor Huyang's origin easter egg of being dropped off by a "mysterious blue box". For those who didn't catch it, this is a reference to the TARDIS time machine and Doctor Who. Huyang's is voiced by David Tennant, the 10th and 14th Doctor.
There are several that you missed, such as Proto-1, a self repairing hermit of a droid that ran a scrapyard on the planet Boonta. He assisted R2 and C3PO while they were in the service of Thall Jobin, Jord Dusat and Kia Moll, while the group were trying to win the Boonta speeder race which won them a contract with a the Zebulon Dax speeder corporation. They ran into Boba-Fett and his BL-series Battle Legionnaire droid BL-17 who were hired by the Fromm gang to erase the team due to their repeated meddling in Fromm affairs. Then there is the monsterous 'Great Heep', which maintained a group of astromech droids that it used to charge itself, destroying the astromechs. R2 was the only recognisable model there, and there were quite a few in the group. Auren Yomm's racing droid, Bix and their rival Bun-Dingo, an assasin droid hired by Governer Koong to knock them out of the drain-sweeper race. He was destroyed when his own sabotage saw him plummet into the drain under increased gravity, smashing him to pieces at the bottom of the pit. There are a whole lot more droids in the series 'Starwars Droids'. Many dont consider it canon, but it bears Lucas' name so I do =p
Chopper is teh Destroyer of Worlds, only holding back on his murderous tendencies out of respect for Hera. He is also the most dangerous babysitter a kid could have, and Jacen is lucky that he has Chopper as his metal sibling.
