Marcel is an antagonist of Rio. He is a wicked poacher who has a right-hand henchbird called Nigel , and two idiot minion poachers called Armando & Tipa . His primary goal is to sell birds to the cold countries, so he'll be rich, but he'll kill anyone who disturbes.
On the orders of a client, Marcel hires Fernando to break into Tulio's aviary and steal Blu and Jewel, sending in Nigel first to pose as a sickly bird so he could let Fernando in. After Fernando brings him Blu and Jewel, Marcel only pays him half of what he promised, and callously sends him on his way.
After discovering that Blu and Jewel have escaped, he sends Nigel after them, and formulates a plan to use Carnival as a cover for their moving of the captured birds. When Fernando returns (with Linda and Tulio, unbeknownst to him), Marcel has him help with their plan. Once Nigel captures Blu and Jewel, Marcel takes the birds to a waiting plane. Before taking off, he spots Fernando trying to free them, but is unable to stop him from running off. As the plane takes off, Linda and Tulio (driving a float) attempt to stop them, but fail. During the flight, Marcel notices that the birds are escaping. With the door to hanger blocked by a pile of cages, Marcel sends Nigel to stop them. This backfires when Nigel is strapped to a fire extinguisher by Blu, and is blown out of the plane, and into one of the propellers, causing the plane to fall. Marcel takes the single parachute for himself, but Armando and Tipa jump after him, grabbing onto his legs as they slowly descend.
During the credits, it is shown that Marcel and the others have been arrested and imprisoned.
