Marcel is the secondary villain of Rio. He is Nigel's owner and the leader of the smugglers.
Marcel planned on selling Blu and Jewel, along with other exotic birds, for a huge fortune. Out of the three smugglers, he is the only one with brains, causing him to frequently denounce Armando and Tipa as "idiots."
He is voiced by Carlos Ponce.
Marcel has a black goatee, fairly tanned skin, Jamaican hair (dreadlocks), and wears a Hawaiian-style shirt. He is also usually seen wearing a pair of sunglasses.
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 for their numerous crimes they have committed, meaning that he and the others are going to be sentenced to life in prison without parolees. Most importantly, the Brazilian authorities decided to hang him and the others for their crimes against animals.
Marcel is evil, wicked, selfish, vain, greedy, cruel, sadistic, cold, and intelligent in nature, unlike the other smugglers. He keeps the birds they capture in appalling conditions, and only pays Fernando half the amount he promised him, showing how cheap he is. He also holds his two henchmen, Armando and Tipa, in contempt over their incompetence and clumsiness. He is even willing to abandon them when their plane started to crash, taking the only parachute for himself, displaying an uncaring nature. The only one he seems to treat with any sort of respect is Nigel; he is often seen petting him, and treating him like a completely competent enforcer and pet. However, this may only be because the cockatoo has never failed him.
- Marcel is sometimes thought to be the main villain of Rio.
