I haven't beaten DMC1 so what feats of life creation or warping space does he have exactly? Did he spontaneously create an army with a thought? Did he make a dimension or something?
When Dante confronts him in his Underworld lair, to give them a bit more "room" to fight he transforms the lair and teleports them both to the middle of space. The final battle takes place with them both flying through space where Mundus fires lighning bolts from the sky at him, aims meteor showers at him and gigantic pieces of...space rock or something. Among his other more usual attacks like lasers and stuff.
He also reveals that it was him who created Trish, most likley as a way of taking advantage of Dantes one weakness his love for his mother.
He is also the master of one of the main bosses, Griffon so he must have created him as well. Not to mention the fact that he was able to tame and control one of the sons of Sparda. Thats a feat in itself.
