Editing Ash Ketchum/Relationships (section)

=== [[Seth (Dinosaur King)]]: ===
Seth is one of Ash's most hatred enemies of all because he works with the Alpha Gang to collect dinosaur cards as well. Near the finale of season 1, he betrays them all revealing his plans is to create a world filled with evolved dinosaurs. He can't let that happened and fights him, but his Saurophaganax defeated all of his Pokémon so easily in one shot using the move "Fire Scorcher". While Jonathan reveals the whole origin of Rex along with his real parents and the Alpha Gang, he and Dr. Z tossed Rex's real parents off the time machine, which angers Ash about hearing Rex's tragic past and Seth's most evil plan he ever did, the whole thing causes Ash to strongly hate Seth a lot for doing that. Seth successfully created the Black T-Rex to fight him, the heroes and the Alpha Gang. While the others fight the Black T-Rex, he, Pikachu, Max and Chomp will fight Seth to stop him from fixing the time machine to travel back in time. Ash managed to get out of one of his traps before he fights him, but during the fight, Seth punched Ash on the stomach before he places his foot on his chest threatening to stomp his chest to kill him, but Pikachu uses thunderbolt attack to zap him giving Ash a chance to get back up to his feet as Chomp joins in by biting his hand. After the Black T-Rex is defeated for good, Seth suddenly got sucked into a vortex, but he was still not finished yet and attempts to take Ash and Pikachu with him to get suck in as revenge for foiling his plans. Ash angrily warns him to never ever try to hurt dinosaurs including his family and his cousin ever again as Seth is sucked into the vortex, after this Ash was extremely pleased to see the mad man is gone for good. But, however in season 2, Seth somehow survived much to Ash's shock in surprised and tells him and the others the whole thing is how he survived is he was found and rescued by the Spectral Space Pirates while being sucked into a vortex. But when he pretends to reform, Ash still doesn't trust him not after what he did back then. But when he stole the red and green cosmo stone they got, Ash knew it this whole time and attempts to stop him before he could make it to the Space Pirate's ship, but it was too late for him to stop him, and he angrily growls and punched the ground in frustration. In "The Search for the Last Cosmo Stone" he betrayed the Space Pirates and decided to take all the six cosmo stones to rule everything. Ash was so angry about this and tries to end this by killing him once and for all. During the fight in "Clash for the Cosmos Stones", his Pokémon team tried to defeat his Cryolophosaurus but it was too fast and strong for them to defeat the dinosaur then it was Chomp who defeated it by using "Final Thunder", but when Seth got away with the black cosmo stone, Ash got so angry he got away again. Max tries to calm him down, but he refused and couldn't let go of his anger unless he ends him. When Seth arrived in the present day and made his Cryolophosaurus held hostage Reese, Dr. Owen and Patrick, Ash's anger become worse even more, after his Cryolophosaurus defeated the six main dinosaurs in one shot using "Snow Crystal" and runs off, he has had enough of this and goes after him in the D-Lab along with Dr. Z, Helga, his Pikachu, Tai, Agumon, Simba, Leonardo, Sora and Jason. After they enter the lab, Ash declares him a fight to the death, so Seth accepts and challenges him to a sword/keyblade fight. During the fight, Seth taunts Ash, which angers him a lot more, so in his rage, Ash uses his keyblade to knock his sword away, then he tackles him to the ground and attacks him mercilessly. With Seth now injured, Ash attempts to kill him by stabbing him on the chest with his Keyblade, but he is only stopped by Pikachu, Tai, Agumon and Sora to stop this and let go of his rage convincing him and successfully comes to his sense finally letting go of his rage. But when the Space Pirates along with their dinosaurs arrived, they attack the heroes outside and so does the D-Lab with everyone inside buried underneath. In the final episode, he, the others along with Seth survived.
