Through the benevolence of Galactus, you have been granted the extraordinary transformation bestowed upon his Heralds, along with unrestricted access to the awe-inspiring Power Cosmic. This transformative process empowers you with strength and durability comparable to the an enraged Hulk, incredible speed and flight capable of traversing the vast expanse of the universe in mere moments, supreme agility almost capable of seizing a fully empowered Infinity Gauntlet from the clutches of Thanos himself, and heightened senses allowing you to perceive and interact with aspects of reality beyond the comprehension of mortal beings.
Moreover, this process elevates your Mind and Soul, enabling you to engage with and communicate with the most potent cosmic forces without succumbing to their overwhelming influence.
The greatest gift of this transformation is the infusion of the Power Cosmic into the very essence of your being. This enhancement fortifies every aspect of yourself, including your physical, mental, and spiritual attributes, while also amplifying your existing abilities with the boundless energy of the universe.
Access to the Power Cosmic bestows upon you remarkable abilities, including Cosmic energy manipulation and projection, giving you mastery over the cosmic energies and fundamental forces of the universe, and enabling you to wield them for offensive, defensive, and utilitarian purposes, Cosmic awareness, which expands your consciousness to encompass the vastness of the universe, allowing you to comprehend and perceive its intricacies on both a universal and multiversal scale, virtual immortality and invulnerability to all but the most formidable cosmic effects, molecular manipulation, resurrection, telepathy, telekinesis, lifeforce manipulation, dimensional travel, time travel, and a myriad of other powers waiting to be discovered through your exploration and mastery.
Lastly, as a symbol of your position as a Herald, you will be bestowed with a unique Item/Vehicle/Weapon. This artifact can be customized to align with your personal preference, much like the Surfer's iconic Board, Frank's trusted Bike, or the wielders of the Axe.
Note: The limitations of the Power Cosmic are solely determined by the extent of your imagination and your willingness to explore and harness it's limitless potential.
