PLEASE HELP!!! I was trying to create a superhero class code, but i ran into this error

File "main. py", line 3
def_init(self, name = "", strengthpts = 0, alterego = "", villain "", powers = "", motto = ""):
IndentationError: expected an indented block

Here is my actual code:
class superhero:

def_init(self, name = "", strengthpts = 0, alterego = "", villain "", powers = "", motto = ""):

# Create a new Superhero with a name and other attributes

self. name = name

self. strengthPts = strengthPts
self. alterego = alterego
self. powers = powers
self. motto = motto
self. villain = villain

def addStrengthPts(self, points):

# Adds points to the superhero's strength.

self. strengthPts = self. strengthPts + points

def addname(self):

if(self. name == "Dr. Cyber"):
print("My hero's name is Dr. cyber!")
elif(self. name == "Mr. cyber"):
print("My hero's name is Mr. cyber!")
elif(self. name == "Cyber Guy"):
print("My hero's name is Cyber Guy!")
else:
print("My hero doesn't have a name")

def addalterego(self):

if(self. alterego == "John Evergreen"):
print("Dr. Cyber's alter ego is John Evergreen")
elif(self. alterego == "John Silversmith"):
print("Dr. Cyber's alter ego is John Silversmith.")
elif(self. alterego == "Johnathen Grey"):
print("Dr. Cyber's alter ego is Johnathen Grey.")
else:
print("Dr. Cyber Does not have an alter ego")

def addpowers(self):

if(self. powers == "flight, super strength, code rewrighting, electronics control, psychic powers"):
print(fly. He is super strong. He can rewrite the genetic code of any object around him to whatever he wants. He can control surrounding electronics to do what he wants. He can move objects with his mind.")
else:
print(Fly. He can rewrite the genetic code of any object around him. he can move objects with his mind.")

def addmotto(self):

if(self. motto == "error terminated!"):
print("rewritting the code!")
else:
print("error eliminated!")

def addvillain(self):

if(self. villain == "The Glitch"):
print("Dr. Cyber's Arch nemisis is The Glitch.")
elif(self. villain == "The Bug"):
print("Dr. Cyber's Arch nemisis is The Bug.")
else:
print("Dr. Cyber has no enemies!")

def main():

newhero = superhero("Dr. Cyber", "John Evergreen", "fly. He is super strong. He can rewrite the genetic code of any object around him to whatever he wants. He can control surrounding electronics to do what he wants. He can move objects with his mind.", "The Glitch", "error terminated!", "0")

print("My Superhero's name is " + newhero. name + ".")

print(newhero. name + "'s alter ego is " + newhero. alterego + ".")

print(newhero. name + " can " + newhero. powers + ".")

print(newhero. name + "'s arch nemisis is " + newhero. villain + ".")
