Those were all done using the same exact wires, only the stretching and wrapping with different tension was altered.
If you understretch enough you can space it how ever you'd like by pulling forward and adding tension
Mohawk (pointy tip) Just needs 2 widths of alien wrap to cover one side of a wire, the alien wrap starts and ends on one side.
The Enigma uses a half of a alien to go around the frames and the center of the wire have the beginning and end of 2 wraps.

If you think of the Alien as a wide width short height diamond or a Rhombus a Mohawk uses the wide width triangular tips to go over the wire, the enigma uses the short height triangle tips to go over the wire.
