As the others changed into their monster forms, Dennis confidently watched while his twin brother David apparently felt aroused by the monster transformations. Dennis has an idea as he noticed his Monsterme profile has a link option to David's profile, likely due to them being twins. He send a link-up request to David as he got confident enough to activate his monster transformation, with David accepting it.
David takes off his black coat and proceeds to undress, taking off his cream jumper and blue shirt before pulling down his blue jeans, and slipping out of his brown shoes, keeping on his boxers and socks. He then looked over to Dennis, who was also wearing boxers and socks after he took off his green sweater, brown necktie, white dress shirt, navy suit trousers, and dark green casual shoes. The two both decide to activate their monster tfs at the same time, Dennis finding a fusion option that he turned on while David wasn't looking.
"Well," Dennis say as he and David both activated their transformation, "If you can't beat them, join them."
Dennis and David find themselves slammed together as their bodies begin to fuse together while scales covered them. The scales mostly retained the twins' skin color with a slight tinges of indigo and red-violet. Within moments, the twins become a single reptilian man with two heads on his shoulders, having a muscular built with pointy ears, a short stumpy tail sticking out from their boxers, four toes on each foot, and three fingers on each hand. They also have short stumpy spines on their back, brown on David's side and blue on Dennis's side. The other monsterized men looked and admired the new monster whose two heads are checking out their shared body.
