When you realize that there are Warframes who correlate to infinity stones...

[(XBOX)Upl0rdYT]

Lavos - reality stone 

Nova - space stone 

Protea/Limbo - time stone 

Nyx - mind stone 

Nekros - soul stone 

Xaku/Harrow - power stone 

(Direct connection to the void and its infinite power justifies Harrow and Xaku being similar to the power stone especially considering that the power stone strengthens other stones and warframes need void energy to continuously use their powers which Harrow can easily supply.)
