Cinescape recently had an article about an Expanded Universe tie in to Episode II: Attack of the Clones. The article mentions that the speeder that Anakin uses in Coruscant belongs to Senator Simon Greyshade, who is featured in the Marvel Comics. Below is the summary of the comic that Simon Greyshade features in, "The Wheel". The summary is taken from Timetales:

"The Marvel Series: The Wheel. (#18-23)"
While meditating in the Force, Luke is knocked out by the terrifying presence of a powerful evil-Vader, searching for him. Leaving hyperspace midway to Yavin to get him medical help, the ?Millenium Falcon? is jumped by TIE Advanced?s. Running from them, the heroes come upon a smashed Tagge Industries ship. A dying Rebel survivor says the Empire destroyed it, made to look like a Rebel raid. Evading a light cruiser commanded by Commander Strom, the ?Millenium Falcon? reaches the enormous casino space station called "The Wheel.? Strom (who arranged the Tagge raid) bullies his way aboard despite the protests of Administrator (and Senator) Simon Greyshade. When he learns Leia is among the Rebels though, the corrupt Greyshade changes his tune and captures Han and Leia personally. Chewbacca ends up in a bar brawl and is taken for use in "The Big Game." In return for Leia, Greyshade will help Strom with his plan.

Desperate to come up with enough money to get them all out, Han becomes a gladiator in The Big Game himself. Even as Strom begins scaring the customers with staged Rebel raids, Greyshade arranges for Han and Chewbacca to fight each other to the death. Either they kill each other in the final round - or they both die. Both Luke (who forces himself with Ben's help to face his fears of Vader, breaking free of his coma) and Leia manage to escape their captivity, as Greyshade secretly raids Strom's ship for the Wheel revenue taken from the Tagge ship. Elsewhere, on Ultaar, Vader hears first word of Captain Valance's search for the "boy with two droids." When he also hears word that the unknown Force-user is on the Wheel, he races out for there. Greyshade faces Luke and Leia, and makes them a deal - if Leia joins him on his yacht with Strom's treasure, he will let Han and Chewbacca live. Before she can decide, Chewbacca seemingly murders Han. Han is actually wearing a blast shield he found on a dead gladiator. Stumbling onto what Greyshade is doing, Strom declares the Wheel under martial law and orders Greyshade and the Rebels killed on sight. Just then, Vader arrives.

Greyshade's Master-Com droid helps Artoo show the Wheel customers the truth about Strom's scheme. The furious customers riot, and Strom and Greyshade kill each other. The heroes manage a difficult escape under Vader's nose, with Luke literally shocking Vader with his rage-filled power in the Force. The group separates, with Luke, Leia and the droids going one way, Han and Chewbacca another.
