Yeah. The other guy mentioned that Stayne was a creation of DS and she was a match for Takion. I just looked up Takion and is shows him and LR fighting at 8 times light speed.
There is no Grandfather Box, so far as I can remember. The "Father Box", first introduced in Simonson's Orion, has been seen a few times, and is definitely a weapon that Darkseid can produce, apparently en mass. In Orion we saw it materialize a gun, out of nowhere/nothing, that would have killed Darkseid with one shot (to the head, at point blank range, suicide style, to be clear).
In Seven Soldiers, it was powerful enough to enslave all of the Sheeda to Klarion's power, and one half of it was powerful enough to give a girl Zatanna-like powers.
In Superman/Batman, the Father Box held in the position of the JLA (in their trophy room) was called 'The Most Powerful Weapon in the Universe!' by a lil Lex Luthor (alternate universe version of Lex who had been transported to the real earth), and Superman said with it he might "destroy everything".
Continuing with the 'box' technology of Apokolips, there is also the "Ancestor Box", just recently introduced in Morrison's Batman, the exact nature of which is still a little unclear but which SEEMS to have gone back in time, infected Batman's history, and turned one of his ancestor's into a 'hyper-adapter' to hound him across time, making his life hell.
And finally, Slig of the Deep Six (one of Darkseid's minions) actually had a Mother Box, so even some of Darkseid's soldiers have Mother Boxes.
