2nd Slave Form:
Master: Himari Azuma
Name: Hyper Carnage
Description: Y/N Tomerarenai takes on a completely different form when Himari Azuma acts as his master the form that Y/N takes on is a different variation the new slave form's name is Hyper carnage it has a less muscular appearance The slave form mainly focuses on speed and less on power and like its original counterpart it has a scarf like organ wrapped around its mouth and neck and has two arms that have chainsaw's that seem to come in split line across the arms and it's head still has chainsaw coming out from its face but the difference is that the form has two engines where the back of its legs Cavs are and has two more pairs of engines on its shoulders as well these engines are not there for show as with them if Y/N Focus his power through the engines A burst of Flames would come out of them as it would give him a major boost in speed but the two pairs of engine that are on Hyper carnage's shoulders are able to move this because Y/N can move them through his will The boy can use them as weapons as if they were to be use to face forward against the enemy and shoot out fire to fight against the enemy

Description: Joyful Hunter is a different variation slave form that Y/N Tomerarenai takes when Nei Ookawamura acts as his master it has a robotic like design almost looking like a child's toy and has two stars on its shoulders and one star on it chest but has a chainsaw sticking out of its face and two chainsaws protruding in between its arms what joyful hunter offers is that it has the ability to enhance its own senses even to the point of having x-ray vision and even allow Y/N to hear from far away distances or even hear a whisper of a conversation between two people but when Nei uses her blessing combining it with Joyful Hunter's ability to enhance senses Promise's Power is greatly bolstered allowing the girl to find things or people even more affectively than before despite joy for Hunter not looking much like a fighter as it does not having great power or speed but it does have some defenses so that it could be able to defend itself and the master as it is able to shoot out small chainsaw flying creatures that come out from the shoulders and chest of Joyful hunter Y/N and Nei can control them and they are capable of cutting down and tear their enemies to pieces before retreating back into the shoulders and chest where the stars are located

Joy: The inspiration I got for the little chainsaw flying creatures for this slave form I got it from the Ben 10 TV series where his crazy ex girlfriend had those alien Nano bots

4th Slave Form:
Master: Shushu Suruga
Name: Masculine chopper
Description: Masculine chopper is a variation slave form that Y/N takes on When Shushu Suruga acts as his master it is a much more bulkier appearance as it bolsters great power but unfortunately it is a slave form that focuses mainly on power and has less speed making it a not so reliable form but despite this Masculine chopper does have a unique ability to extend or enlarge it's chainsaws reach so that it can take out its enemies unlike Shushu Masculine chopper can only do this on its chainsaws instead affecting its body

Appearance:

Info: This a form that Y/N achieves is in the later chapters in the book I won't tell how that happens but I can tell you guys that Y/N does gain a boost in his physical and sensory abilities but is weaker then his true slave form and unlike his true slave form Y/N needs blood in order to keep using the form or continue using the form if not then Y/N will revert back to his human form

Joy: I would very much love it if someone could make some fan art for the chainsaw man slave forms I would be very grateful if you did then please give me a link to it so that I could use them for this and I will make sure to give you a shout out and damn sure that everyone know that it you who made the slave forms
