The Flash got his powers from a chemical accident. He was in his lab when a lightning bolt struck a shelf of chemicals, dousing him in a combination of substances that interacted with the lightning's energy. This event altered his molecular structure, giving him super - speed.
The way Flash acquires his powers in the comics is often a result of a chance encounter with a complex set of circumstances. Usually, it involves a laboratory incident where he's exposed to a mixture of chemicals and a burst of lightning, granting him his speed powers.
Well, Flash acquires his powers when he's exposed to a combination of a certain chemical mixture and a powerful bolt of lightning. This unique event triggers his super-speed abilities.
It's possible he gains enhanced physical abilities like super strength or speed. Since his heritage is often tied to some special genetic traits, these could be unlocked upon the revelation. For example, if his heritage is linked to a powerful clan, he could inherit their natural combat prowess. He could also find out about special chakra control abilities that are exclusive to his bloodline, which would give him an edge in battles.
The 'godlike' powers could be integrated as an evolution of Naruto's existing chakra powers. Maybe he discovers a new form of chakra that gives him 'godlike' abilities like the ability to create or destroy matter at will. The 'flash' powers could be added to his movement skills, like he can move at super - speed by channeling this new form of chakra.
I'd recommend 'The Wheel of Time' series by Robert Jordan. The main character, Rand al'Thor, starts to uncover and master his immense powers throughout the series. It's a rich and detailed world with lots of power discovery and growth.
His spider - sense and the Flash's super - speed could work together amazingly. The spider - sense could warn him of upcoming threats just in time for him to use his speed to avoid them. He could also use his speed to get to the source of the danger that his spider - sense detects more quickly.
Barry's super speed could make the pregnancy journey both exciting and nerve - wracking. He could use his speed to quickly get things for Iris like her favorite food or pick up pregnancy books from the store in a flash. However, his speed also means he has a higher metabolism and his body operates at a different level. There could be concerns about how this affects the baby. For example, if he holds Iris while running at super speed, there might be questions about the impact of the vibrations or the sudden movements on the unborn child.
