Astro Boy fanfic

I was taking inspiration from the Astro Boy 2009 movie I'm thinking instead of actually Astro Boy who would be way too pure for most worlds I was thinking maybe someone reincarnates and becomes Astro Boy either appearing in a single world or going on a Multiverse Adventure my inspiration from the 2009 movie is that he has access to the blue core and the red core so not only does he have like double the power but he also has the ability from the red core shown in the movie to absorb objects and augmenting himself similar to how me out of control robot at the end of the movie started absorb materials to get bigger and then absorbed that gunship and used it as its own weapon but instead of like the whole mutating get all big and crazy it would be mostly to give him an edge in universes like DC or Marvel or worlds that would have like a crazy higher level that normal level Astro Boy with just his finger laser and giant arm beam just couldn't compete an example of the use of the red core would be if he went to Marvel he'd be able to start absorbing vibranium to start augmenting his normal body so instead of it being made out of regular steel or titanium body or whatever Astro boys made out of he can start upgrading himself with vibranium as well as other metals he finds and gains access to he can also absorb technology that he can then use in his body so let's say he gets a chance to absorb Iron Man's repulsors he can then use their special qualities like for flight or since they seem to be a concussive beam as a low-powered knockout or something like that I hope whoever reads this kind of gets the idea.
