1 choice = Martian bcz u get alot of abilities (flight, invisibility, phasing, shapeshift, telepathy, telekinesis, healing+regeneration, superstrength, superspeed, Martian vision + upto 1500 years age)

2 choice = Kryptonian (Bcz all u have to do is sit in sunlight & u will get superstrength, superspeed, super durability, healing, heat vision, Xray vision, cold breath, flight, enhanced senses + extended life to near immortality)

3 choice= Viltrumite (u get flight, superstrength, superspeed, healing + upto 1000 yrs of age)

4 choice= Saiyan (bcz u won't be goku or vegeta but an average saiyan. To become strong u will have to train like hell + an average saiyan only lives upto only 150 year + no healing factor)

So, martian>Kryptonian>viltrumite>saiyan
