Map of Infinity (Episode)

Map of Infinity is the eleventh episode of the Ben 10: Ultimate Alien series.

Plot
From the previous episode, Aggregor has absorbed the powers of Bivalvan, Galapagus, P'andor, Andreas and Ra'ad, transforming him into Ultimate Aggregor. Ben as Humungousaur, battles Aggregor in a fit of rage and anger. As Ben was about to beat Aggregor some more, Gwen stops him with her force-fields. However, the attacks did nothing to Aggregor, as now he has Bivalvan's invulnerability. He's now also immune to Gwen's mana attacks, which is from Galapagus. He then battles Kevin and Gwen and defeats them. Ben tries to attack him again, but Aggregor defeats him with one, earth-shattering punch and then leaves. Ben wakes up from Aggregor's attack to see Azmuth in his face. Azmuth seems upset by the Ultimatrix's workmanship and its evolutionary function begging for trouble, which was made from his former assistant, Albedo. Azmuth then tells that Aggregor is now looking for the most important object in the universe.

Azmuth brings Ben, Gwen and Kevin to Galvan Mark II, where he explains that the reason Aggregor absorbed the powers of the aliens was to become unstoppable on his quest to collect the pieces of the Map of Infinity, which can give the user the power to travel anywhere. Aggregor wants the Map to reach the Forge of Creation and become even more powerful. To make sure the map's power doesn't fall into anyone's evil hands, Paradox divided the map into four pieces and placed them in random places. The group's job is to collect the pieces before Aggregor can obtain them. Grandpa Max is forced to stay off the mission as one of Aggregor's attacks damaged his whole nervous system, and is supposed to be giving him a new one.

Ben, Gwen and Kevin go to the place where the first map piece is held, a half-fire, half-ice planet called Mykdl'dy. The team has to wear Plumber suits or they could die in the planet's atmosphere. They find the temple where the map piece is held, but it's guarded by white Necrofriggians (Big Chill's species). Gwen tries to make peace with them, but after Ben mentions taking an artifact, they attack Ben and he must stay as Big Chill, because the transformation destroyed his Plumber suit. When Big Chill proves to be too weak, Ben becomes Echo Echo, but later becomes Ultimate Echo Echo. They manage to get in the temple and the Necrofriggians leave them, but their leader says they won't be able to pass the following traps without a guide. Kevin accidentally springs a trap and a giant spiked hammer comes and seemingly crushes them.

Gwen was able to protect them with her powers and now Kevin's suit is torn, too, but he's able to survive when he absorbed the stone on the hammer. Gwen springs another trap and she and Kevin fall into a vat of boiling acid, but Ben manages to save them. They then fight a two-headed monster and after defeating it with Ultimate Echo Echo's sonic discs, they go on ahead. Ben once again springs another trap and they run through a corridor of poisoned darts. They reach the door containing the map piece in it and Ben lifts the door a little along with Kevin, then changes into Four Arms when it proves to heavy. Together they lift the door just enough for Gwen to go inside and collect the piece.

However, upon entering she learns that she was struck by a poison dart earlier and immediately passes out. Aggregor comes and reveals he made Ben and his friends go through the traps for him so he wouldn't have to do it himself. Aggregor takes the map piece and leaves. While Ben holds the door, Kevin picks up Gwen and they are able to escape the temple by Ben crashing through the walls as Cannonbolt. But once they reach the ship, Ben changes back to his human form and passes out. Kevin is able to get Ben and Gwen in the ship and takes off. Kevin heals Gwen from her poisoned dart and Ben survives but now has a sunburn on half his face. As Kevin and Gwen thought it was over, Ben says he will make Aggregor pay and promises to get one one of the last three Map pieces left before he does.

 * When Ultimate Echo Echo is flying on top of the acid, his fingers are blue.
 * When Ben as Four Arms jumped back from the wall, he had taken a small step back, but in another scene he had taken several steps back.
 * Ben's jacket stripes appear on the wrong side in one scene.
