Less is Morrison (Japanese: ライバル登場！マサムネとダンバル！！ The Rival Enters! Morrison and Belldum!!) is the 26th episode of Pokémon: Advanced Battle.
The gang is having lunch. Ash quickly eats his lunch, as he needs to teach Snorunt to use Ice Beam properly. May also wants to train her Pokémon, but is angry when sees Munchlax eating all of her Pokémon's food, but suddenly, it goes away. Snorunt goes to use Ice Beam, but fails. Suddenly, Ash catches a sandwich and a guy comes yelling to give his sandwich. However, as he was running down a slope, he bangs to a tree. As Ash goes to give his sandwich, they see Munchlax eating it in an instant. The guy screams and tells them "he fells better now." The guy introduces himself as Morrison, who wants to go to the Hoenn League. Ash introduces himself, as he also wants to win the League.
Morrison also tells him he plans to become the Pokémon Master, just as Ash wants. However, they begin to argue, so the decision is to have the battle. Ash sends Pikachu and Morrison a Beldum. Beldum starts with Take Down, but Pikachu dodges and uses Quick Attack. Beldum uses Take Down once more (as it is the only attack it knows). Pikachu evades and counterattacks with Thunderbolt. Beldum charges with Take Down, so Pikachu dodges, but this time Beldum attacks Pikachu and hits him. Pikachu is knocked out, but stands up and goes away as another Take Down is initiated, but Beldum hurts Pikachu again. Beldum uses Take Down once more and Pikachu counters with Iron Tail, but both Pokémon are defeated.
Both trainers go to their Pokémon, as both lost. Morrison thinks as he has more badges than Ash does - he has seven of them. However, Brock tells him that the Hoenn League is 2 months before it starts, shocking Morrison. Ash shows his and Morrison counts all 7 badges. Morrison goes away, to get the final badge. Munchlax is not seen again. Team Rocket is starving, having only one cookie. James thinks they need to split it, but Jessie tells them they need to play rock, scissors and paper. Unsurprisingly, they fail, but they do notice their cookie gone. Team Rocket begins to suspect someone in the group stole it and they fight. However, Munchlax stole the cookie. May calls it back and wonders what it should do with it. Brock proposes the May's purple surprise, but May thinks it is like feeding a bottomless hole.
They found Pokémon Center, but Morrison as well. Morrison tells them there is no need to rush and there is no Gym on the island, so goes to the Center to give Beldum a rest. Ash goes to do with Pikachu the same. Ash and Morrison walk and begin to run, having a contest. However, the result is banging themselves on the counter near Nurse Joy. Joy takes Pikachu and Beldum to treatment. At night, Ash goes to eat, so Morrison tells him he can eat twenty of them. Ash raises the stakes and Morrison does the same. During the bath time, Ash goes to go with Max and Brock, but Morrison tells him he can't overcome the heat, so they both go deeper into the hot water. Morrison turns the heat up and soon they drown. Next, they are seen cooling down and Joy gives Morrison and Ash the Pokémon they gave for treatment. Morrison and Ash give her all their Pokémon for treatment.
Ash thinks it is time for sleep and Morrison goes to do the same - outside. May asks if it isn't dangerous to sleep on a tree, but Morrison tells Beldum takes care of him. He asks if anyone wants to sleep on the tree, so Ash accepts this offer. Morrison sends Beldum who pulls him up. Ash tells that he has Pikachu who will keep him, but falls down, though Beldum catches him. Next, Ash ties a net, like Morrison to sleep. Ash admits it is good to sleep on the tree, so Morrison tells him that he has a lot of friends - Beldum, the leaves, stars and the wild Pokémon. At the morning, May mixes the berries for "her pink surprise" (a recipe made by Prof. Oak) and gives it to Munchlax. Munchlax eats and has its belly full. Max tells it that he has a lot of them, so it needs to ask. However, Munchlax is asleep.
Ash and Morrison search for a field to train. Unsurprisingly, they both picked the same spot and begin to argue. They begin to arm wrestle and both won and lost. So, they go to race to the top of the mountain. Team Rocket spots them and Meowth sees Beldum and thinks it would massage their boss after a long day, so James and Jessie are convinced to capture it. Ash trips over and falls down. Morrison begins to laugh at him, but falls down as well. Their stomachs begin to growl and seeing an apple, they race to get it. Still, each one gets a half of the apple and they both admit the other one is good. Suddenly, their Pokémon are stolen and they are trapped inside a cage - Team Rocket arrives. Team Rocket flies away on the balloon, so Ash and Morrison try to go out of the cage by smashing and tackling it, but with no effect.
They charge together and escape the cage. They charge to jump across a gap. Morrison begins to fall, but Ash got his hand and pulls him up. Ash and Morrison charge and get to the top of the balloon. Morrison and Ash pop the balloon up by bitting on the ears. Ash and Morrison demand their Pokémon, but Jessie and James know they have no Pokémon. This doesn't stop them and they fight using themselves. Jessie sends Seviper, who uses Poison Tail. Ash and Morrison stand up and use take down. James sends Cacnea, who uses Sandstorm to push them. Seviper wraps Ash and Morrison and pushes them down. Ash and Morrison stand up once more and charge towards Seviper and Cacnea, tackling them - they are pushed on the cage and Pikachu and Beldum are free. Team Rocket does not give up as well - Seviper goes to bite and Cacnea attacks with Pin Missile. Pikachu hops on Beldum - Seviper and Cacnea miss. Beldum charges with Take Down to Cacnea and Pikachu uses Iron Tail on Seviper. Pikachu attacks them with Thunderbolt and Beldum blasts them off with Take Down.
Morrison and Ash congratulate each other and their Pokémon. Morrison goes on a ship to get the eight badge, while the gang needs to go to Slateport City for the Grand Festival. Ash and Morrison promise to meet each other in the Hoenn League.
