There’s
a statement from Dwayne McDuffie that says Kevin would’ve probably still been able to defeat Aggregor if he absorbed young Ben’s Omnitrix instead, though it would be more difficult. I’m pretty confident this statement is unusable after the WoG restrictions, but out of curiosity I wanted to see the implications this would have.
First off, this Ben would have to be post-Secret of the Omnitrix, as it would be basically impossible for Kevin to defeat Aggregor using young Ben’s Omnitrix without Way Big’s power. This means Kevin would have access to at best 18 aliens:
- Heatblast
- Four Arms
- Diamondhead
- Wildmutt
- Stinkfly
- Ripjaws
- Upgrade
- XLR8
- Cannonbolt
- Wildvine
- Blitzwolfer
- Snare-Oh
- Frankenstrike
- Upchuck
- Eye Guy
- Way Big
- Grey Matter
- Potentially Ditto
Grey Matter and Ditto are irrelevant since they don’t have the typical scaling, which leaves at best 15 aliens not counting Way Big.
Since OS characters are 1/10th later characters and Kevin only gets 1/10th of their power, that would mean absorbing those 15 aliens would only give Kevin a 1.15x power increase compared to his base form. Ultimate Aggregor is 6x base Kevin and this hypothetical Omnitrix absorption would be relative in strength, so we can calculate OS Way Big’s strength based on that:
- 6 - 1.15 = 4.85
- 4.85 x 10 = 48.5
- OS Way Big’s strength: 48.5x base UAF/OV characters
Again, probably not useable, but neat.
