It seems that in the clone wars, IG-100 unit used utapau starfighters, which means they have arrived in utapau during the war, but then in Ep. 3, why did the starfighter didn't show up in battle of coruscant? How about why the natives of utapau seem surprised when Kenobi showed up? (I know, I know that they where being watched...) Anakin Skyobiliviator 06:49, July 15, 2011 (UTC)
How about Episode III was written before all the other Clone Wars holes had been filled? -- Riffsyphon1024 07:29, July 15, 2011 (UTC)
IG-100s aren't as plentiful as other CIS battle droids. They are seen as either Grievous' bodyguards, or specialist infantry. So not that common to start with.
The P-38 starfighter was used by no more than 2 Magnaguards in star wars canon, so seeing them elsewhere would only be a bonus. Sidious gave one to Cad Bane as part payment, as per Bane's specific conditions for a difficult mission. The P-38s were produced on Utapau by a major starship manufacturer, so it would seem that they were available for sale to the galaxy at large, not just the confederate navy. The Utai actually used them against the CIS at the Battle of Utapau.
In regards to their surprise at Kenobi's arrival, I don't see why the Pauans or the Utai wouldn't be surprised to see a lone jedi since they were essentially occupied by the CIS army. Hope that answers your questions.
In answering the second questions, the Utapau natives must have known war was coming to their planet, however Greivous and the droids were already there and had them under their boot; the guys who met Obi-Wan may've been merely ACTING surprised so Grievous wouldn't suspect them of anything.
