Quark - from X-Force Series 3. I remember reading a Toyfare article on how this Mojoworld rebel fighter was voted one of the most obscure characters to get a figure from Toybiz.
Mojo - This awesome figure was the BAF (build a figure) for the Marvel Legends Series 14. Although some critics have said he is too small, he works perfectly fine with the 5" scale figures.
Spiral - Mojo's lieutenant came from the X-Men Invasion series.
