HypnoWarren

Wypno is the slash ship between Warren Stone and Hypno-Potamus from the Teenage Mutant Ninja Turtles fandom.

Season 1
WARREN & HYPNO, SITTING IN A TREE

Hypno tests his new canon with the air conditioner, saying that it's good but aim needs work. Warren is beside him, looking inside and asking if it's okay for his hair to be inside of it. Hypno assures him that it'll be fine, but if he's concerned then they can go back to sawing him in ten. Warren says it's very painful to be literally sawed that way, and Hypno says it's painful to saw his friend as well. They're interrupted by a knock on the door, Hypno saying that "they" found them. Warren says to play it cool, and Hypno says that's hard to do without an air conditioner. Warren says he nailed it as they fist bump and Hypno says it was a great set up.

They then get tossed out of their apartment in an explosion caused by Baron Draxum, who demands Warren's gauntlet. Warren starts to fight Draxum, when he tosses a brick wall at him. Hypno then uses his magic to turn it into flowers, and the continue to fight him. Warren then ends up inside the turtle tank and orders April, as she's a member of his fan club, to help Hypno. Outside, Hypno fights Draxum demanding to know where they have Warren. One of them points out that Warren is in the turtle tank, now fighting Donnie, and Hypno jumps onto the windshield saying that he'll save him. Hypno is then captured by Draxum, and in a fit of rage Warren starts pressing buttons on the Tank to free him. He accidentally presses Nitro, which causes the Tank to rocket off, Warren and Hypno calling and reaching for each other before it speeds off.

The turtles initially refuse to help Warren, but he tells them how Hypno is the only person in his life and means everything to him. They all begin to cry (except for Donnie), and agree to help. They go to meet Draxum, Warren putting up the front that he's going to make the trade. Hypno tries to say it's a trap, but Warren hears it as "I love you" and says that he loves Hypno as well. He the betrays the turtles and Draxum agrees to trade Hypno for them. Warren hugs him when he's reunited, but Hypno interrupts with an apology. He mesmerizes Warren to give Draxum the gauntlet, since it was the only way Draxum said he would let Warren live. When he hands Warren over, Draxum the betrays him, capturing Hypno and the turtles as well.

Hypno frees himself and begs them to help him save Warren. They give in, but only because it's April's birthday and she wants to save her idol. They attack Draxum and get Hypno, but his arm gets cut off and the gauntlet gets taken in the process. Warren gets mad at April over the loss of the gauntlet, and April says that to her and Hypno he's kind of a big deal, and would rather have him. He says he'll haunt her and Hypno happily cuddles up to him. He gives him a kiss on the cheek and says that's just like Warren to say. He then summons his doves to carry them off and suggests they go home and make fun of game show contestants.
