Let's see, he has intangibility, memory manip, willpower manip, an instance of existence erasure (though likely a gag feat; up to you to decide if we use it), energy absorption, some scans of containing something that coukd heavily damage the universe, a feat of dying and being transported ibto his little device and then coming back, invisibility, summoning others of his kind, a form that does have universal powers, the speed advantage, hackimg and informarion analysis or sonething like that, and telepathy.
Pretty sure screwing with one of his combatant's forms that require all three personalities to agree on something in order to perform an action plus intangibility, potential soul manip from others of his corporation, memory and willpower manip will really help him here. Also forgot the time slow that makes the speed gap evem worse.
So yeah, I think you're underestimating a certain soneone here.
