Eternals has every legend choose their power, focusing the cosmic energy used to make them into their chosen specialty. If so in the MCU film, each Eternal’s power set reflects their personality. Phastos is a genius, even by Eternal standards, so his abilities permit him to take advantage of cosmic energy to design, construct, and control innovation in ways that his teammates can’t. The melancholic Sprite, who bemoans the confidence in nonexistent structures and her permeant innocent appearance, specializes in making illusions.
As the colleague with the strongest confidence in the Celestials’ plan, Ikaris has specialty powers similar to his different teammates as well as an interesting one, making him perhaps the most imposing Eternal. While not as strong as Gilgamesh, Ikaris has upgraded strength and a similar type of energy projection to Kingo. Ikaris’ capacity to fly is similar to Makkari’s super speed, and keeping in mind that he isn’t as fast as she is, his power is perhaps more versatile. This set Ikaris in the best possible position to implement the Celestials’ will, despite his absence of authentic group leadership.
While the Eternals may have chosen their powers in the MCU as they did in the comics, another possibility is that their Celestial creators decided their powers instead. The Celestials probably won’t have had the option to provide each cosmic capacity to their creations, so instead, they give them specialty abilities to make a decent group for shielding worlds from Deviants. Regardless of whether by decision of the Celestials or himself, Ikaris’ capacity to fly is important for why he’s perhaps the most impressive colleague in Eternals.
Eternals explains the beginning of its nominal heroes, who are synthetic humanoids visually indistinguishable from humans, however with god-like powers to assist them with shielding worlds from Deviants. As well as never maturing, each Eternal possesses superhuman strength, speed, sturdiness, reflexes, and quick mending. Each Eternal can also take advantage of the same cosmic energy that the Celestials used to make them and the incredible Infinity Stones.
