User blog:Metal875/Mini-Stars Power - MP9

Intro
In this game, the plot is that Bowser has stolen the Mini-Stars from the sky. And apparently, it seems that these Mini-Stars are actual stars in the sky. In the ending cinema, the Mini-Stars are returning to the sky--all of which Bowser said he was going to put to use. It's shown at the end, when many burst after his defeat, that he meant this as they were going to power him.

But... just how powerful is absorbing those stars?

Clarifications
First, we'll assume that Bowser only stole the Mini-Stars that Mario and his friends could see. Since they had a telescope, and Bowser was collecting them from all directions, let's assume he absorbed all the stars in the galaxy. There are 100,000,000,000 stars in the Milky Way. As our high-end, we'll assume he absorbed half of all the stars in the visible universe (since there are still stars remaining even as the Mini-Stars escape, and because it states that Bowser'll take all of the Mini-Stars), of which there are either 10,000,000,000,000,000,000,000 to 1,000,000,000,000,000,000,000,000 of them. We'll halve the latter, since the page admits there are likely more out there. Also, as a basis for this, we're going to use the GBE of the Sun, which is 6.276e+41 Joules.

The Feat
Power (Low-end): 6.276e+41 × 100,000,000,000 = 6.276e+52

Power (High-end): 6.276e+41 × 500,000,000,000,000,000,000,000 = 3.138e+65

Results

 * Low-end: Solar System level+ (4-B)
 * High-end: Multi-Solar System level+ (4-A)
